Coolant Leak Repair

If you car is leaking coolant from your radiator and you car help with your vehicle repairs, our staff can help. We are experts at finding leaks and diagnosing overheating problems.  For the last 15 years, we have spent each summer fixing overheating problems for locals and college students alike. 

The coolants job is to keep your car cooled. Engine coolant circulates through your engine where it absorbs heat and then circulates through the radiator where it is cooled down. Then back to the engine block and head again. As long as the coolant is able to flow freely, and there are no leaks, the coolant can do its job.

How does a coolant pressure check work?

Coolant pressure checks are used to test for leaks in the vehicle’s cooling system. The most commonly used device is a hand pump that connects to the neck of the radiator, along with its adaptors connecting to the different sized caps. Another way to perform a coolant pressure check is by using air, and connecting it to the coolant over flow hose. The style has an adaptor that connects to the radiator caps and allows a temperature probe to be inserted into it. 

When testing coolant pressure with a hand pump, you, first, need to make sure that the radiator is full. Then you need connect the correct adaptor to the neck of the radiator. Then, you will need to connect the pressure tester to the adapter. After, slowly apply pressure to the system. Stop applying pressure once you have filled the range of the system, which should be about 13-16 psi. This should hold the pressure for about 20 to 30 minutes. If not, there may be a leak in the system. This would be the time to check for that!  

When testing with shop air, you need to attach the adapter to the pressure probe. You then need to attach the air to the system and increase the regulation system pressure. After the desired setting is reached, you’ll need to shut off the shop air. The system should hold pressure for around 30 minutes. If the pressure drops before that, there is a leak in your system.

The cooling system, in an environment that is very hot, with a number of reactive materials like various types of metal, plastics, and rubber. Over time the coolant becomes corrosive. Small pieces of debris and other materials break down and interfere with circulating the coolant. As these particles start to block the small passages in the radiator, it restricts the coolant from flowing, which results in overheating. Corrosive coolant can actually eat away at your cooling system which leads to leaks as well.

The new coolant is full of anti-corrosion additives. These additives neutralize the reactions that lead to cooling system corrosion. Eventually, additives are used up, leaving the cooling system vulnerable to leaks and problems. Coolant pressure checks make it easy to locate the source of a leak. With hundreds of possibilities, lets take guessing out of the equation. 

We offer recommendations for when your cooling system should be flush and inspected. Your friendly and knowledgeable pros can also test your coolant for freeze point and PH to see if it needs to be flushed out and replaced (if you’ve added straight water to the cooling system we need to remove it asap). Fresh coolant in your system is required to protect against corrosion. We suggest a coolant flush every 2-5 years.
