Temp gauge is a bit dodge on my fairmont, never leaves the blue! and i drove 5 hours the other night! how can i check it???

well firstly make sure the temp switch wiring is connected on the thermostat housing.

i spose the only other way to check it is to either try another if you know someone who will let you... or buy anothe one.

my car runs really cold, but i have noticed a big difference with the V8 Radiator, plus a cooler thermostat. plus at night your car will run cool anyway.

whats it like during the day, plus if you give it a bootfull??

Does it move at all? If it does it's most likey not the guage.

How warm is the top radiator hose after a bit of driving? Could well be an open thermostat.

I'd blame the thermostat as well. I recently spent $20-something on a new one (the 3rd one in as many years) because my old one was seized shut. The new one appears to be seized open.

If anyone ever finds a working thermostat, buy a lottery ticket.

Yeah if the guage actually moves but not much then I'd bet my money it being the thermostat. Either its too cold (72 degrees or something) or its stuck open.

if the guage doesnt move AT ALL, wire is off, sender is shot or the guage itself..
if it does move but not very much, thermostat is too cold, ie wrong one fitted, jammed open or missing altogether, or dirty terminals on the sender

Mine has been like that for moooooonths! It doesn't seem to affect anything except maybe fuel consumption. I will replace it in the coming weeks though...

This happened to me. I replaced the thermostat with a ford one, now she sits just below half and never moves above that. The advantages was better fuel consumption and the heater kicks ass now. I see my thermostat opening and closing because I didnt drill the 3mm hole like people were saying to....it kind of looks cool seeing it work

im thinking thermostat too, just replace it and see what happens!

i replaced my thermostat because my car never moved from the blue with an aftemarket (non-genuine) one, and problem solved. I did notice however that someone had drilled a 2-3mm hole through the old one, as though they wanted the car to run colder. Why would they do this? Also I checked the thermostat in a bucket of water, and it wasn't seized open, so how can a tiny hole make this much difference?
