not exactly the time of year to have this thread but it is what it is.

so i noticed that my thermostat was stuck open b/c i could never get up to operating temp when it was cold. but during summer would stay around 90c. decided to change the thermostat. put new one in, burped system and now running at 100c on guage. went out and bought a behr 78c thermostat from indy and put the NEW NEW one in. STILL running at 100, but it kinda looks like its the gauge that is flakey. sometimes it will flick between 90 and 100.

AND now i appear to have a radiator leak!
i've had the top hose off and im getting water into the radiator and its not backing (not due to leak, only seems to leak under pressure) up in the radiator so i assume that the thermostat is opening and sending it through when warm.

is there a way of testing to see if i need to replace the instrument cluster?

how much of a PITA is it to replace the instrument cluster?

can someone help me sort this out!?!?!? because im
