Need help. My car keeps losing water and cant find out were it is . I have replace the water pump,thermostat,thermostat housing, fan clutch. This all started after I pulled the motor and replaced rear main seal and oil pan gasket. Any hints why this is happening.

Have you pressure tested the cooling system? This is step 1.

Are there externally visible leaks (wets spots on the ground)? Are your carpets wet near the console?

And are you seeing white "smoke" from the exhaust?
