02 Mercury Cougar Blowing Hoses

[ET16]

Thinking further, past the water pump, it might be easier to put a used engine in. The engine has to come out for the head work, no?

Don’t blown head gaskets also cause milky looking motor oil????

Only if the leak causes coolant to leak into the oil. It's possible that a head gasket can just leak coolant externally.
