I have a 2001 Buick Century (3.1) that keeps losing water/ coolant. What can be wrong?
It looses about 1 gallon a day, with no visual leak. The tempuature guage never rises more than half way. I learned that these motors have a bad rep for leaking intake manifolds. Could this be the problem or what? Thanks for your answers.

If it is the intake manifold gasket leaking do not buy a aftermarket gasket. GM has redesigned the gaskets and they work great. You will also need to replace the 8 bolts that secure the manifold to the cylinder heads.
BTW, one gallon a day and you cant find the leak, if its no leaking externally it must be leaking internally.

Common leak point is the intake gaskets at the very end of manifold on these engines.

Could be intake ,head gasket, or cracked block.Do white clouds come out of the exhaust?
