So after my BHG replacement, Bottom end rebuild and installation or my reverse glow gauges(YESSSSSS) I go to start my car and as soon as i turn the key to Accessories my temp gauge shoots to just below hot. Well I start the car and let it run for awhile nothing is overheating, cabin air is nice and warm, no built up pressure in the coolant hoses or lines. I have a brand new radiator in, but no Thermostat in the engine sooo there shouldnt be any over heating really. I read a post about ppl replacing the coolant gauge sensor. So i had another one laying around and replaced it with the one that was in. No change at all, Now after I installed the gauges the temp gauge doesnt read cold when the engine is off (have to fix the gauge) But my question is why is the gauge reading almost hot before i even turn then engine over? Maybe the ECU needs a reset? I dunno. Sorry if this doesnt make sense lol I just have everything runnin through my head just now. Thx in advance.
