Temp quick rise after replacing Thermostat
I just replaced my thermostat because I think the mechanic i used didn't put the right one in. Back story, My water pump blow a bearing out last year and since he was there, I asked him to replace the thermostat. After that, the truck seemed to run hotter then normal, nothing crazy. It ran at 200 plus/minus 5 degrees and when I pull a hill, it climbed to 215 or so, EMPTY, no load. Which I thought was wrong. Didn't think much of it because the fan would kick in and cool it off.
Okay, now today. Saturday I bought a 180 degree from Napa since it been pretty damn hot here, I'm in Oregon right now. We were going camping and I was pulling my 4 horse trailer which has living quarters in it and I didn't want to risk overheating.
Now, that I have driven the truck a few times, my Smarty Touch display shows me that the temp climbed to 235, like in less then 10 seconds, by this time the fan is screaming at me and the temp drops just as fast as it climbed. Then settles at 182-190 and doesn't have a problem. The stock gauge never shows the spike.
Want could this be? Did not loss any coolant when I swap them out. It did NOT do this before I swapped.
Air pocket? Bad thermostat? Bad temp probe?
I guess I should have order the better brand, but I didn't have time.
Truck specs are in the signature. Any thoughts would be helpful.
