Re: 91 200q pushing H20 out ofcoolant tank

I would look for a leak in your head gasket, head or cylinder walls -- a
compression test would be a good place to start.
There is also a chemical test you can perform on your coolant that will
detect exhaust/combustion products in the coolant. Auto parts stores may
carry the chemicals, or a shop can no doubt perform the test for you.
You could also rig an adapter to pressurize a cylinder at a time through the
spark plug hole with the aid of an air compressor. BTDT. Keep it 100 psi
for a while and see what happens to your coolant level without the expansion
tank cap on.

Very good advice, but also dont forget something simple, ( we always hope for
simple first) ;o] like a bad thermostat restricting flow and raising
system pressure at higher rev's ( spirited driving ) I just replaced the
failed thermostat in one of my cars and many of the hoses upstream of the
blockage were swelled considerably due to the raise in system pressure.
