    If it is leaking antifreeze, the easiest diagnostic procedure is to perform a vacuum test on the coolant system. If the leak cannot be determined at that point, degrease the engine and place an UV dye (coolant compatible) in coolant and run the engine. Shine an UV light on the engine in order to see where it is coming from. If this test proves inconclusive, prepare to test for internal head gasket leaks.

    Curious as to why the EGR valve is suspect.
