How do u set the timeing on 96 grand prix GTP with 3.4L V6 DOHC?

This link may help you. Coolant Elbows Leaking 3800 Pontiac GM Chevy 3 8 Liter V6 engine water...

If it were mine, I'd want to be very sure what it was and so I always use a Repair Manual I can see and read, but that me.

As you see I provided you the models you can apply the transmission :The 4T65E-HD (code MN7) is a heavy duty version of the 4T65-E used with more powerful engines such as the LS4 V8 and L67/L32 supercharged V6. Applications: 2.93:1 MN7 Pontiac Bonneville SSEi L67 Chevrolet Impala L67 Chevrolet Monte Carlo L67 Pontiac Grand Prix GTP/GXP Buick Regal GS Buick Riviera L67 (97-99) So ,yes you can!

Maybe a backflushing of the cooling system can help to make it cool more efficiently.

Sediment can build up in the cooling system causing a lack of flow of coolant.

Also, the thermostat could be stuck closed, as others have suggested.

Well, the short answer is "yes". But - it isn't nearly as simple as just bolting the supercharger onto the intake and VOILA!, now you're supercharged. The procedure that you're inquiring about is commonly referred to as a "top swap", and there are numerous parts you will need for both engine as well as the transmission. Why the transmission? Because the GT and GTP use different gear ratios and the GTP has a 4T65HD as opposed to the 4T65E that is in the SE/GT. You will also need to have the PCM reprogrammed to accomodate all of these changes.

HERE is a great website that has a ton of very useful information, regarding this and many other Grand Prix topics.

Hope this helps and thanks for using FixYa!

Ignition switch faulty.

Both knock sensors are screwed into the side of the cylinder head between the front 2 cylinders.

It could be the Oil pressure sensor is bad and leaking oil, There know to go bad and will leak worst when driving as the oil pressure goes up.
Good luck and hope this helps.
