1998 Grand Am Water Outlet Housing Problem

Our 1998 Grand Am was bought brand new in 1998. After 8 years the original water outlet housing had to be replace due to a crack. The new part lasted 1 year. After that we had to replace it again for the same problem. 2 months later that part cracked. We replaced it again and also replaced the upper and lower motor mounts thinking that was the cause of the constant cracking. That did not work either we now had to replace the water outlet housing just after 1 month. What could be the problem?

I’m not familar with your engine. Is it the 3.8 liter engine? Is the “water outlet housing” made of plastic? If it is you might try to see if you can get an aftermarket one made from alumium. Just a thought!
