Gentlemen,

We've had this '97 for some time; it seems the coolant goes low on a regular basis. While there are no visible leaks, I suspect a bad intake manifold. Does this gradual loss of coolant point to the bad EGR valve/intake manifold situation? As far as I know, there has been no different exhaust appearance, and there is nothing apparently wrong with the engine oil. Maybe it is a small, consistent leak in the suspect area?

Opinions, please!

Thanks,
Jack C.
