Top Signs That It Is Time For A New Car Radiator

- Tuesday, January 20, 2015

Over time, car radiators age. As they age, a variety of issues can arise signaling to the car owner that it is time to replace the radiator. Radiators can sustain damage that is irreparable, and this will also result in the need to replace the radiator. It can be necessary to replace the radiator in order to prevent multiple future breakdowns.

Old radiators can develop cracks and pin holes.

Radiators are made of metal. Almost all metal ages and weakens due to oxidation. As the metal in your radiator weakens, it becomes susceptible to decay and failure. The constant heating up and cooling down of the radiator causes the same stress on the metal as bending a piece of wire back and forth in the same area on the wire. It will eventually break. In the care of your care radiator, the break is a crack along a tube that drains the coolant from the top to the bottom of the radiator. Under pressure a great deal of coolant can be lost very quickly.

Pin holes are created by oxidation of the metal in the radiator.

Everyone is familiar with rust that forms on unprotected iron. This is oxidation. Oxidation is a corrosion that erodes the amount of metal available. As time passes, more and more of the metal oxidizes until small openings or pin holes start to appear. The high pressure inside the hot cooling system of the car will spray coolant though these tiny pores as you drive. Stop leak and other home remedies can slow the leaks for a while. The only real permanent fix is to replace the radiator. 


A badly clogged radiator can need replacement. 


Radiators can get clogged or blocked in two or three ways. Debris from inside hoses or the water pump can break loose and lodge in the radiator core. The accumulation of this material over a few years will reduce the cooling efficiency of the car radiator. Likewise, small amounts of oxidation residue can join the party and increase the chances of the car overheating. If stop leak is added to this mix, flushing the radiator and cooling system will probably not product effective results. A radiator replace is the only sure option.


Damage to the front end of a vehicle often results in radiator problems.


If a collision of any type creates significant movement of the car's front end materials, the radiator will be affected. Older radiators can even be damaged by the jolt of the impact. In older cars, the radiator may be forced backward onto the metal blades of the cooling fan. This can create immediate and extensive radiator damage. In newer cars, the radiator is cooled by an electric fan that will have little effect on the metal car radiator. However, pieces of the material from the front of the car can still impact the radiator core. The crash can bend or crack the unit. Any of these types of issues can be enough to force the need for a radiator replacement.

Auto Coolant Servicing Five Important Factors You Must Know

- Saturday, January 10, 2015

Until things go wrong, we do not realize the importance of our vehicle’s coolant system. Auto coolant has a very important role in keeping your engine running without damages. Most of us ignore the need for regular auto coolant service. If this sounds like one of your follies then here are some important factors that you must know about auto coolant service so that you can respond in a timely fashion whenever there should be issues with your car’s cooling system.

1. Auto coolant protects your engine from overheating. It might be a very simple mechanism but without a fully functional cooling system, serious damages could be caused to your car’s engine. Sometimes the hoses that carry the coolant to the engine under high temperatures may have been damaged or worn. Without coolant, the engine may seize under high temperatures. Around the car’s engine, other car parts are closely packed, so when the engine’s temperature increases, other components around the engine including electrical wiring, fuel pump and other sensors could be damaged. Therefore, the first thing you should do is to take your vehicle to a repair shop for auto coolant service.


2. One of the problems why most car owners fail to take their vehicle for auto coolant service regularly is that they are not sure how frequently their vehicle’s cooling system requires attention. This however depends on the nature of the coolant used by your car manufacturer. There are different types of coolants in the market; if your car manufacturer has used long-life coolants then you may not require frequent auto coolant service. However, if what you have is not long-life coolant, then you may have to go in for regular servicing and checkup once every 10,000 to 12,000 miles.


3. When you take your vehicle for coolant top up or cooling system checkup, make sure to do an overall checkup of your vehicle. A full work up can catch any other problems that are likely to happen and prevent damages to your vehicle. With everything working properly, the vehicles coolant system can optimally operate.


4. Always take your vehicle to a trusted and experienced repair shop so that you receive reliable auto coolant service. At times, there could be other minor problems resulting in your car’s over heating issues. This can be identified only by an experienced technician. Your vehicle’s overheating problems will not be fully resolved even after coolant top up or after coolant service until the other factors contributing to your vehicle’s over heating issues are addressed.


5. Most importantly, as soon as you notice that your vehicle is overheating try to stop your car in a safe place and get help. Do not ignore the issue and continue to drive thinking that you could make it to your destination. This could prove to further damage your vehicle that may lead to time consuming and expensive repairs.

6 Important Signs That Indicate The Need For Fuel Pump Repair

- Tuesday, January 06, 2015

The role of fuel pump in your car is to send a steady flow of fuel to the engine. As you can imagine, the fuel pump is one of the most extensively used components of your vehicle. This means that your fuel pump is subjected to greater wear and tear and may require regular attention. Failure to attend to your fuel pump could result in complete stalling of your vehicle and overall poor performance. Therefore it is important to keep your fuel pump in quality condition with regular fuel pump repair and servicing. Here are six important signs that indicate that your fuel pump needs attention.

1. No sound of fuel pump when you try to turn on the ignition – The fuel pump starts even before the engine starts. When you turn the key the fuel pump should be engaged and once engaged the fuel pump will produce a whirring noise. Pay attention to this noise to ensure that your fuel pump is engaging without any problem.

2. Failure to start – If you are frequently running into hard starts when you are trying to turn on the ignition, it could be an indicator that your fuel pump has needs repair or replacement.

3. Your vehicle losses power when you are trying to accelerate – When accelerating your vehicle, the fuel pump should supply more fuel to the engine. If the fuel pump is not functioning properly, whenever you try to increase your vehicle’s speed, your vehicle will lose speed instead.

4. Sputtering of your vehicle at high speed – Another symptom of faulty fuel pump could be sudden jerking of your vehicle when traveling at high speed. Your vehicle will sputter without any warning and will reduce speed.

5. Difficulties while climbing uphill – If your vehicle is experiencing difficulties climbing uphill, even without towing a heavy load, it could indicate the need for fuel pump repair. The fuel pump is not supplying the additional power required to rev up the engine to climb steep grades.

6. Your vehicle stalls frequently – If there are problems with your fuel pump, it will stop pumping fuel to the engine resulting in unexpected stalling of your vehicle.


If you are experiencing one or more of these symptoms, it is important to take your vehicle to a repair shop for fuel pump repair and servicing. This will ensure your vehicle operates at optimal performance and protect you from any associated risks. 

Important Questions To Ask While Looking For Your Radiator Repair Shop

- Sunday, January 04, 2015

Are you in search of a radiator repair shop to service or replace your radiator? It is important to be able to trust the repair shop your car will be serviced at. Here are some of the important questions that you should ask while deciding which repair show is best for you.

How many years of experience does radiator repair shop have? 

Yes, the experience of the radiator repair shop matters a great deal while selecting your service provider. Your car’s radiator is one of the most important parts of your vehicle. Only experienced technicians should be entrusted with the repair or replacement of this important component of your vehicle. Only an experienced technician will be able to identify the problem correctly. Wrong diagnosis of the problem will result in wrong solutions that could lead to expensive and unnecessary repairs. If you do not want to run into unnecessary problems, research each repair shop to ensure they possess adequate experience.


Is your radiator repair shop a licensed and insured service provider?

Secondly, it is vital that you are sending your vehicle to licensed and insured service providers. In case there should be any issues in the future with insurance claims, your insurance company will inquire into the history of the vehicle. If they were to find that your vehicle has been serviced by a repair shop that is not licensed then they may reject your claim. You will need to make sure that you work with licensed repair shops in your area.

Does your car repair shop have a respected reputation?

Often customers complain that car repair shops take advantage of their ignorance. Are you dealing with an honest and trustworthy repair shop? Your car repair shop should be keeping your best interests in mind. A respected reputation in the industry can be earned only by offering consistently good services to the customers. If you do not want to be misguided when you send your vehicle for radiator repair or radiator servicing, then you will need to find a reputed service provider.


Is your radiator repair shop fairly priced?

There are no standard or regulated rates for car repairs. This allows each service provider to set their own rate. Make sure to shop around for the best prices before you settle with any particular service provider. Once you find a reasonably priced car repair shop, establishing a long-term relationship can lead to added benefits and discounts for all your future radiator repair needs.

Why It Is Best To Take Your Car To Repair Shop For Fuel Tank Repair Or Sealing

- Wednesday, December 31, 2014

Very often car owners are tempted to take care of fuel tank repair needs themselves rather than taking their car to the repair shop. Yes, it is true that fuel tank repair kits are available in the market. You might think that you just need to seal one or more leaks in the fuel tank and it’s a fairly simple job. However, repairing your fuel tank may not be as easy as it sounds.


Many people think that they can just patch up the leaky fuel tank in just minutes and let it dry but the process is more extensive. You will first need to remove the fuel tank from the car. You cannot do this without really getting your hands greased. Once the fuel tank is out of your car, you will need to empty the fuel tank completely so that there is no fuel left in the tank. You will need to find a container to safely store the fuel and ensure necessary safety precautions are taken until you refill your reassembled fuel tank.


You will need to clean your fuel tank thoroughly with appropriate cleaning agents. Before you can proceed any further with your fuel tank repair and sealing, you will need to let the fuel tank dry completely. Once the fuel tank is completely dry, you need to find the punctures or holes in the tank. These should be marked clearly and sealed from the outside using duct tapes before you actually use the epoxy sealers. It takes an experienced technician to decide whether the fuel tank leaks can be just sealed or whether it needs to be replaced depending on the extensiveness of the damage. Unless you have adequate experience in this area, you may not be in a position to judge.


You will need to find reliable sealers to get the best results. Before you pour the liquid sealers, you will need to block the fuel outlets temporarily. This ensures that the sealant fuel is not drained out completely before sealing the punctures. You will need to make sure that the sealant covers the entire surface of the tank evenly including the damaged areas. The excess sealant will then need to be drained before the fuel tank is restored in the vehicle.

Though it may seem to be a series of simple steps, this process can be extensive. Rather than subjecting yourself to hassles and safety risks, you can take your vehicle to your local repair shop for fuel tank repair and have the issue resolved with the help of an experienced technician. 

The Most Common Car Heater Problems

- Sunday, December 28, 2014

Car heaters are an important comfort component of your vehicle. These crucial heaters that keep you warm inside your car may require periodic attention to function optimally. Unlike other parts of your car, your car heater does not demand too much attention but car heater repair is a common problem. Pay attention to minor car heater repair issues to avoid expensive replacements or repairs.

1. Instead of blowing hot air, your car heater could be blowing cold air. Your car heater actually makes use of the heat generated by the engine rather than having separate heating equipment. If your car heater is blowing cold air then it means that the heat from the engine is not made available to the heater system. You need to take your car to a car repair shop to get your car heater diagnosed and repaired.


2. Car heater not blowing any air. The second most common problem is that the car heater fails to blow any air. In this case the problem is with the fan. You may have to service the fan or replace it depending on the nature of the problem. There could also be blocks in the vents that are preventing the air from reaching the car interior. Either way, you need to have your car’s heating system tested by a qualified technician so that you are not shivering behind the wheels.


3. Car heater controls not responding. There could be problems with your car heater’s control system. As a result you may not be able to increase or decrease the heat level in the car. A working heating system should be able to control the heat level to maintain a comfortable environment within your car. Your car’s heating system has to be diagnosed thoroughly by your car heater repair company to identify the problem.

Whenever there is a problem with your car’s heater, it is best to take it to your car repair shop rather than trying to resolve the problem yourself. If you try to repair your car heater yourself, you can aggravate the issue and end up with expensive repairs. It is important that you do not delay taking your car to the repair shop because faulty car heating system could be the result of some other underlying issue. Always take your vehicle to a licensed and insured repair shop in your area to preserve the integrity of your car. 

How to Measure a Radiator

- Wednesday, December 17, 2014

Basically, there are two radiator designs: DOWNFLOW and CROSSFLOW.

It isn’t that one design is better than the other; they simply relate to the functional design of the vehicle. However, it is important to determine how the measurements are to be made. The Tanks are located on either side of the core. The rails are located on the opposing sides. ALWAYS MEASURE THE CORE ONLY.

The engine coolant flows down in the radiator from the top tank to the bottom tank.

The CORE HEIGHT is always measured between the tanks, across the fin area only.

The CORE WIDTH is always measured between the rails, across the fin area only.

The engine coolant flows across the radiator from one side tank to the other side tank.

The CORE HEIGHT is always measured between the tanks, across the fin area only.

The CORE WIDTH is always measured between the rails, across the fin area only.

The CORE DEPTH is the thickness of the radiator. The easiest way to measure the thickness, is to place a small piece of wire between the fin so each end is flush from one side to the other.

Mark the wire and measure it to get the radiator’s thickness.

How to Replace Your Car’s Radiator

- Thursday, October 23, 2014

Radiators on older model cars were made of copper and brass alloys. This made them easy to repair by soldering the cracks or holes that caused leakage.


However, a number of later model cars include radiators with aluminum cores, which have plastic top and bottom tanks. These newer radiators can be damaged by forcing off a hose, over tightening a clip or even by improperly removing the pressure cap.

Damage to the new radiators is impossible for a home mechanic to repair, usually resulting in the replacement of the whole radiator. The one good thing about replacing the newer radiators, is that they are lighter than the old ones and usually have simple fittings which make them easier to remove.

Safety first

Before starting, disconnect the battery to remove any radiator that has electrical connections.

Drain the radiator

Make sure the engine is cold, then take off or release the pressure cap on the radiator. Some cars have a tap or drain plug in the bottom of the radiator, open it and the radiator should drain.

If no water comes out, poke the drain-plug hole gently with a piece of wire, or unscrew and remove the tap. However, if there isn’t a plug, or you are unable to clear the blockage with the wire, disconnect the bottom hose where it attaches to the radiator.

Drain the coolant into a clean container, then strain it through muslin to remove the rust or dirt so that you can save it and re-use it in the new radiator if its still good. Check the strength of the solution with an antifreeze hydrometer.

Watch it

While you are disconnecting and removing the radiator from the vehicle, pay close attention to the parts you remove and how you remove them. When installing the new radiator you will be attaching the same parts, in the same way you removed them from the old radiator. You may want to make notes, draw a diagram or even take a picture of the radiator before removing it. This will save you a headache later, if you forget how to attach something or if you forget to attach something.

Remove the hoses

Loosen the hose clips and ease off the hoses by gently twisting them back and forth. Don’t try to pry the them off with a screwdriver: you may wind up damaging the hoses, if you plan to reinstall the current ones. If you plan to replace the rubber hoses, it is much easier to just cut the old ones off.

Oil and transmission fluid cooling lines

Before disconnecting the oil and transmission fluid cooling lines, get another container ready to catch any oil or transmission fluid that will leak out. Next, unscrew both lines from the bottom of the radiator and let the oil, left in the lines, drain into the container. Place plastic sandwich bags over the ends of each line and fasten them with rubber bands. This will keep oil from leaking out onto the ground or garage floor.

Make sure you check, and top off, the oil and transmission fluid when you are finished installing the new radiator.

Clear the way

See if there are any fan-shroud pieces to remove, that will allow you to remove the radiator from the vehicle. However, there is a chance that you will only need to unscrew the radiator mounting clips. After the clips are removed carefully remove the radiator from the vehicle, making sure it doesn’t get hung up on any other parts and that there isn’t anything else attached to it.

Install new radiator

Before starting, set both radiators side by side and check the new one over carefully to make sure it is a match to the old one. Gently guide the new radiator into place, be very careful not to bend any of the cooling fins. Damaged fins will diminish the radiator’s ability to cool the engine properly.

Next install the clips and make sure the radiator is secure. Screw in the oil and transmission fluid cooling lines, being careful to line them up properly so you don’t strip the threads, which cause a leak.

When reattaching the hoses, tighten the clips firmly, but don’t over tighten them, which could cause the clips to cut into the hoses or crush the plastic stubs on the radiator.

Refill the radiator

After you are sure everything is connected properly, fill the radiator with the mixture of coolant/antifreeze recommended by your specific auto company. Also check and refill the oil and transmission fluid as necessary, due to leakage.

Is It Time To Think About Radiator Maintenance?

- Wednesday, October 22, 2014

Do you get a physical every year or just wait until you’re REALLY sick to go to the doctor? It’s probably a little of both, but I’m sure you do a lot of preventative maintenance, like taking vitamins, eating healthy, and exercising, to keep your body healthy and to stay away from the doctor’s office.


Well, your car needs the same TLC that your body does! I’m sure you know about the basic types of maintenance that a car needs – your oil changed, your tires rotated, your windows cleaned, etc. – but what about your radiator? Do you ever check that? Maybe you should.


Regular radiator maintenance is an important and integral part of the overall “health” of your car. An engine’s cooling system is relatively simple when it comes to its design. Why? Well, it’s because your engine has to remain at a certain temperature in order to work properly otherwise you could have engine failure. So, knowing some basic radiator maintenance is absolutely essential for any who owns a vehicle.


What does your radiator do? Well, radiators keep your engine cool while it’s working and your car is working, driving you around from place to place. Radiators are like the “wingman” of your car’s engine. Without your radiator, your engine would not last through the cold nights and would easily overheat during simple drives.


Here are some simple tips you can use to maintain your radiator:

- Keep your radiator fluid filled! Coolant or radiator fluid should be used in a 50/50 mixture with water. You can purchase a pre-mixed bottle of 50/50 Coolant from your local auto repair shops.

- Make sure your radiator cap is on tight. Your radiator cap is designed to help keep your coolant system pressurized and to keep your coolant from boiling.

- At least once a year, an external radiator cleaning needs to be done. There are two options for this.

- You can use a hose with a nozzle and a soft nylon brush to clean the exterior of the radiator. Once your car is completely cool, gently brush the radiator fins, in the direction of the fins. When you’re finished brushing the fins, use your hose to rinse off the radiator by streaming the water from outside to inside.

- You can take your car to the staff at J-Mac Radiator and they’ll take good care of your radiator! They will clean your radiator’s exterior professionally.

- Lastly, it is important to flush and fill your radiator at least once a year. The professionals at J-Mac Radiator professionals recommend a flush and fill for winter called “winterization” for your car. 

Depending on how much you drive, you may need to have more than one flush and fill per year. Why is a flush and fill important? Simple! It is to ensure your cooling system will run well and won’t become clogged with lots of particulates. Over time, your car’s radiator can become blocked with debris from the engine that is cycled though the dirty coolant and will eventually completely clog the cooling system.

- There are two ways to flush and fill your radiator.

- You can flush and fill your radiator yourself. We’ve posted a blog earlier this year on how to do so.

- We recommend bringing your car into J-Mac Radiator. Our car care and radiator professionals will flush your radiator chemically and then by hand, in two directions with water. Then refill your radiator with the proper coolant you need and have your car ready for the ride of your life!
