engine not listed in above drop down menu has 3.8 6 cylinder . car was overheating checked hoses , fans ,radiator ,replaced radiator cap and thermostat filled radiator have a leak somewhere as lot of it on asphalt recently over heated again and steam arising from block and when popped hood was wet beneath steam seems to originate from the area where water pump connects to engine maybe a gasket ? or possibly the waterpump itself
on second water pump in 4 years told needed to put a higher quality of one in first one spun bearing in the pump and second one is having steady leak from behind mounting flange throwing coolant all over as u drive $100.00 difference in price for a standard water pump to name brand not counting labor i save here by doing myself vs waiting on a shop and paying hidden fees good luck wont be buying another pontiac anytime soon right at 130,000 miles
3rd water pump..changed housing to timing chain and replaced timing chain as well.Replaced upper and lower radiator hoses, flushed system, new motor oil and short whole cooling system done..2 1/2 months later..same problem..losing coolant, possibly water pump again..this car is costing me way too much!
Water pump is a major issue,have had it replaced 3 times,and now i parked it,water pump leaking again,tired of this car!
