Ever since I got my 77 suburban I've never seen the gauge go past 1/4. Could be a bad gauge, or the previous owner removed the thermostat because they were lazy, or the thermostat is stuck open or some weird temp. I have a new 195f oem temp one ready to install, and the flat type gasket.
i was told i needed permatex thermostat goo so i have some of that. what do i do with it?? when installing the thermostat what is the best way to get air out of the system? i plan to not flush all coolant, just replace whatever spills out when i remove thermostat.
thank you for any information that will help me. i don't want to overheat my engine by trying to replace thermostat and doing it wrong, and i don't want it to leak afterward :'(
i found this video for the same type of truck. he did not use any goop or mention anything about getting air out of the system:
edit: and i think for the 99, instead of replacing thermostat myself, i'm just going to wait until my envoy is sold so i have some $$$ to buy intake gaskets and injection spider and have the shop do it then. since they have to drain coolant anyway.
