My car is leaking yellow fluid and when put coolant in it will leak the yellow fluid. And I put more coolant in the overflow tank and stop leaks also and idle the car for fifteen minutes. It was leaking more than usual but when I turn off the car it stop leaking.

Hi and thanks for using 2CarPros.com.

It sounds like an engine coolant leak. Can you tell me aproximately where the leak is located?

The best thing to do is pressure test the system. Basically, you supply pressure to the cooling system which will cause the coolant to leak so you can locate the problem.

Here is a link that discusses how to check and repair a leak:

Take a look through that link and let me know if it helps.

If you have other questions, let me know.

Take care,
Joe
