Alright so it's probably just me not getting the air out of the system but heres the deal
when i start my car and it's cold the temp gauge will run up like normal but then spike past normal temps for a second and jump back down. Before the temps spike i get no heat at all.
When the car is warm but has been turned off for a few minutes and then turned on i get heat for a maybe a minute then goes dead cold and the temps spike again and when that happens my heat comes back
is it just air in the cooling system or maybe a thermostat? Engine is a GM 3.1 out of a malibu. I've followed the hanes manual on bleeding and it states:
open bleeder valve and fill surge tank
close bleeder valve and surge cap
run until operating temp
open surge cap while idling, and fill if nessicary and then reinstall cap
everytime i do that it just seems to leak the pressure, i dont lose any coolant and when i take it for a drive once the temps spike the car holds temp perfectly.
i'm not an expert but i need this to just work for as long as it can while i figure out how i am going to get a new car

had similar problems with my NA miata after a coolant flush despite it working just fine prior. ended up replacing the thermostat and it fixed the issue.
anyways, all you really need to do is jack up the front of the car and idle the engine with the heat on as youre adding coolant. it should remove most of the air

i've been wanting to swap the thermostat to the 180f one instead of the 195 it's just an absolute bitch to get to on these engines. I guess i'll have to try it then. The one thats in is less than a year old and is the oem replacement one. Who knows maybe it is sticking.
