Re: Temperature Gage Going Haywire
It could also be other things... if there are air bubbles in the system it can cause this, but teh root cause of the air bubbles would be a failing water pump, failing head gasket, or a bad rad cap, either way you could first try bleeding the air out of the system then fill the system properly and see if it comes back. I don't see too many t stats going bad but I guess your jeep is an 05 and it could very well be the t stat.
