Thanks for reply Ken.I am a Honda Master Technician, this 05 Buick Rendezous V6 is a freind who said my daughters car is overheating, can you install this thermostat and coolant he thought would fix her problem. The complaint/issue their having is the Temp Gauge on the dash is reading 1/4 or so. But less than half way nice and steady. Then at times it goes quickly up to 3/4. Then back to 1/4 again. So.
After checking a few things I dont think the car is overheating at all, with a scanner reading engine coolant temp.I see that when this episode occurs temp is around 220. Also when the low fans come on. Which I now learned is normal on this car. And again after fans are running for like 45 seconds the gauge goes from 3/4 right back to 1/4!
So now im thinking there is a problem with the switch that sends the signal/temp reading to the gauge!
Or the gauge or that circuit. Another reason is a GM Tech said that on this model at normal temp. The gauge should be at 1/2 right in the middle! Maybe resistance no good in that switch!
What do you think?
