Hey Guys. I am all of a sudden having all kinds of problems with my Envoy. Multiple problems I will be attempting to diagnose at the crack of dawn tomorrow but one of them has me stumped and hoping someone with a bigger brain than me (Not hard to find) can help me understand what's going on.
I'll try to keep it short. I was going through a carwash on Sunday and as I am going through I noticed the engine temp rising. It got to about 20-30 degrees over the center line on the temp gauge (I can't remember if that center line is 200 or 220).
So it heated up and then I pulled out and started driving, Within about 15 seconds after I started down the road, the temp immediately went back down to normal and has stayed there ever since. I mean it was instantaneous. I could see the needle move back down very fast. It was as if all of a sudden coolant started circulating into the block.
I REALLY do not feel like I have a sending unit or gauge problem because a week ago I was driving it after being parking for a few months and it got very hot, just under overheating but that was because the coolant was very low. I put coolant in and it was fine. I drove it a 100 miles today in some traffic, some city stop and go and all was normal.
Has anyone ever see this type of thing before and did it turn out to be a warning sign like maybe the water pump is going bad, or the thermostat is close to failing?
Thanks!
