I have a 2001 Pontiac grand prix gt 3.8. Water was leakin so I changed out water pump and put in a new one. But its still leaking. Could it be heater coil elbows?
It sure could. Replace them with the metal ones. They're much better and will last indefinitely. HTH. -Jim
Change the elbows even if they're not leaking (kind of like you did with the water pump). They are prone to failure and a $5 part becomes a $300 part if it blows on the road and you have to take it in to a shop like I did. After that check hoses and intake gaskets. If its a very minor gasket leak treat the system with Bars Leak and save yourself a ton of money. Leaky hoses are sometimes just clamps that need tightening. Old hoses should be replaced.
