I have a 1992 Pontiac Grand PrixSE,Ihad to replace timing belt and chain,since then it has started having problems with charging and the engine getting to warm.After I drive a short distance it starts getting warmer(the temp. hand use to not move above "C")but I haven't caught it running hot,when I then turn the car off with the engine warm it doesn't want to crank back up,except by putting a set of jumper cables on it and boosting it off.It's a 3.4 V-6 and runs real good besides that.
