Question about 2002 Pontiac Grand Prix
Have a feeling that my head gasket is worn out along with my upper engine seal. There is a slight coolant leak coming out of upper seal sometimes and as far as i've noticed its not leaking into the motor. I do not have a loss in heat or problems of that nature, however there is a slight hesitation whenever the car is in drive and you maintain speed, it does not hesitate when you are getting up to speed, could that be due to the gasket and seal being bad?
3.4 engines are notorious for bad intake manifold gaskets.
if you are going that deep into the engine it is not much more
work to change the head gaskets at the same time, make sure you also replace the head bolts.

on the 3.8 ussaualy not the head gasket but the upper intake gasket . antifreeze leaks inside intake and into the cylinder. very common. the new gaskets are much thicker.or the plastic plenum the black plastic part on top of the engine goes bad around the water inlet and need to be replaced . when i do either job itell the person to replace both at same time saves money and headaches in the near future. hopes this helps .....and cost for a shop to do this $1100 to $1500

SOURCE: Coolant level sensor pops out
yes. it sounds like your sensor is held in with a retaining clip which looks to have been lost in the swap over from old to new parts. take the car back to the shop that serviced it and tell them about your issue. hopefully not too much damage was caused by the overheating. i hope this helps and good luck!
