Have your water thermostat checked for the correct heat range, its normal for a temp gage to raise then drop as the thermostat opens and closes ,, thats its job,, if you have replaced it before, it could be a higher rating than before

I had the same problem with my 2001 Pontiac Montana and the intake manifold gasket. This is a major problem with these 3.4L engines, if you are in the states I'm pretty sure there is a class action law suite against GM for this. I had my manifold gasket replaced and it was about $1000 CAD. You need to get your vehicle looked at right away as this could cause major engine damage, coolant will leak into the engine and soon enough you will be replacing that too.

Could also be a blocked radiator core, - check coolant or airflow is not restricted, Ensure any radiator leaks are repaired, Ensure coolant level is correct, without airlocks - bleed as necessary on re-fill, Check operation of cooling fan - ensure fan runs at appropriate engine temperature - if not check sensor switch and associated relay operation. Thermostat is located at the end of top radiator hose where it connects to engine housing. Posted on Aug 11, 2009 • 114 Answers Sounds like the thermostat needs to be replaced. If you do the work yourself be sure the temp threshold is correct and the flow direction is correct when installed.

Idle the vehicle for about 20 minutes and then feel the upper radiator hose. It should be hot to the touch. Drive the vehicle and when the temp gauge falls to 'cold' stop and feel it again. If it is much cooler to the touch than before the thermostat is defective or wrong.

It started when it overheated. We changed the thermostat, then water pump, then temp sensor gauge and the temp gauge goes high but only when the heater stops blowing hot... Air pockets will make the guage do that, and also cause your heat to come and go. Also, a poor radiator, as in rotting, or plugged up, will cause high temperature issues.
