2006 Pontiac Grand Prix Coolant Loss

Asked by Mar 19, 2014 at 10:58 AM about the 2006 Pontiac Grand Prix Base

Question type: Maintenance & Repair

So my GP was getting hot. I took it into the shop they replaced the front cover gaskets, installed a new water pump, and replaced upper and lower intake manifold gaskets. It still leaks antifreeze. Took it back and they replaced the clamp on the upper radiator hose. It is still losing antifreeze and smokes.

Take it back again.

I take it back every other day. It goes away for a little bit then comes back.

My 2006 Grand Prix was leaking coolant through a crack the plastic heater hose fittings and I replaced them with Aluminum ones (DORMAN part #47065HP). They are two little 90 degree fittings on the engine near all the pulleys. The alternator and belt tensioner will have to be removed to replace them. Have them replace these. It is likely the issue.
