Question

its at the top of my engine by the s.belt under the power st.pump,its on a 2002 ponti. montana by the intake

Answer 1

extremely common on the 3.4 v6 engine ... lower intake manifold gaskets split and start leaking coolant and sometimes engine oil. being a gm tech. i have seen many many of these.. probley done 100 myself. it is a fairly spendy repair, maybe around the 700 dollar mark.i would recommend a dealer repair as it can be a pain to do. if you have them done or do them yourself, be sure to have the distributor o-ring replaced as well. its only a 2 dollar part and is much much cheaper to replace while the engine is apart. hope this helps

Answer 2

It is a good chance that the O-ring for the heater connection under the P/S mounting bracket has failed.
also possible that the intake plenum gasket has developed a leak.
It is mechanical failure, don't try to repair with Stop-Leak, it won't fix it, and now you have some crud in your cooling system that will contribute to more problems later.

Good Luck

Answer 3

Probably the intake gasket. The gm 3.4 engine was noted for intake gasket leaks, you might even get warranty if you complain to gm.

Answer 4

Sound like you need to replace your 'Head Gasket'. You can first try to re-torque the head bolts (when engine is warm) or try a engine sealer with copper in it. The copper sealer worked for me and did not effect the radiator or heater core.

Answer 5

Atleast you dont drive a Honda

Answer 6

sounds like maybe the water pump or just a loose hose.

Answer 7

Not sure about this one. I suggest the web site "Autopro.com." Someone there should have the remedy.
