Hello all, afterany issue when buying this car and it being fixed by car shop I for the past few months noticed the temp sensor usually sits at 210. We have noticed it goes slightly above that and then back to normal. I have changed just the thermostat and it got worse, to where I bought the thermostat and housing from Chevy. Just replaced it and it's still doing the same issue. I am not sure if this is normal or needs to be addressed. I noticed the upper hose is warm to the touch after driving 20 minutes, and the lower hose coming from the thermostat is warm it seems from the engine temp. I am thinking it might be the water pump?? Any ideas suggestions or help would be amazing.
