Temp Gauge

My temp gauge is off the chart high...but I just had the water pump replaced etc and the car is running fine would it be my cluster that is broken? Cause if you slap the top of the dash the gauge does come back to normal for a bit before jumping back up to max.

u could try and use some other cluster see if it solves your problem and then take it from there.. i have an extra one i would've lent it to you if you were in ottawa

Thanks for the info...will give it a shot and see how that plays out. Cause I drove it all day today and it ran perfectly fine.

Uday, perhaps you didn't purge all of the air out of the system when you topped her up. The interior heat selection should be set to on, the filler cap left off while engine is running until the coolant reaches the point where the thermostat opens. That way you can visually see the level rise and fall in the filler neck based on physically moving the throttle by hand to assist the level to drop slightly. After sufficiently warmed up, elevating the rpms by hand and constantly topping the coolant at which point when the fluid wants to overflow from the filler neck, replace the cap. The occasional extreme deflections of the temp gauge could have been caused by the coolant thermosensor encountering an air pocket. Since the thermosensors are co-located by the filler neck, and that spot being the highest elevation of the cooling system, it's natural for the air pockets to gradually make their way to the highest point (the coolant thermosensor area).
Hope this helps.

Thanks John will give it a shot and let you know if it worked.
