How do I know if I need a new charge air cooler?
If your charge air cooler is leaking, you probably need to replace it. Many original equipment coolers leak when they are new, and only get worse as time goes by. A cooler that is leaking will allow the compressed air out of the turbo charge to escape before it gets to the engine. This will result in power loss and poor economy. A quick leak down test of the charge air cooler, will tell you how bad the situation is.

What is a “Leak Down Rate” Test?
A leak down rate test is a test which shows the amount of leakage from your charge air cooler. The basic procedure is to pressurize the cooler and then see how long it takes the air to escape. We sell a set of tools that will allow you to test your cooler in a safe and accurate manner. Your local diesel engine service center will also have the equipment to test your cooler. We recommend that the cooler be tested at every oil change.

How Much Leakage is Acceptable? See the chart below.
