Does anyone know why the coolant in my gar is milky green? It was parked for about 1 1/2 yrs. Is it just old, or do I have the beginnings of a bigger problem? Thanks in advance.

It may be milky becasue someone added radiator sealent to the coolent...it looks milky after a while. OR.....you have a blown head gasket. Drain your cooling system and flush it...add new coolent and drive it for a while..Weeks....then check it again..Good luck -Travis77z

If someone stored your car for awhile maybe they put some water-soluble oil in the radiator to keep the water jackets and other components of the cooling system from rusting. It will cause the fluid to look milky.

First thing to do is check the OIL. If the engine is cold, run it for a few minutes, and check the dip stick. Is it milky also? If so, you have a leak between your coolant and oil and you better fix it. I'm not sure about Zcars, but in most American engines, it points to your head gasket.
