thermostat? temperature sensor?
hey guys, a couple days ago, i noticed that my temperature gauge is way low, specifically if i sit an idle it will go almost up to half, but while driving 50mph it drops to near the C (btw its about 30 outside)
odd thing is that the heat is still pretty warm, at least warm enough to warm me up, so i was wondering if this was a thermostat problem or temperature sensor problem
thanks
chris

wow, that was a ...errr compounding my confusion
i will see if i can play withthe temperature sender, they are cheap and easy to replace
then if not, is there anyway i can replace the thermostat without draining my radiator
lastly, is there a problem???
thanks

The Hayne's said to drain the block too, but I ended up just draining the radiator and everything worked out fine.

are u guys kidding me?
during cold day crusing on the hwy..it's quite normal for the coolant temp to drop.
-he has heat, also car warms up properly when not on hwy..so i HIGHLY doubt it's the thermostat.
-the gauge works, moves with change in temp...so i doubt it's the gauge sensor.
-his fan works (no overheating i assume)..the coolant temp sensor works.
you guys want him to rip open the coolant system for something that's normal.

ahh I thought he said his temp gauage wasn't working. Mine seems to just have 3 settings; Hot, Cold, and normal. It doesn't really fluctuate any based on outside temps.
I kinda thought this was a fun install to be truthful, not expensive at all

If you have the abilities to do the job, I say do it.

why do u think in 30 degrees or lower temp the coolant temp should not drop when the car is cruising on hwy?
i guess it wouldn't hurt to do it..but IMO it's not needed..at least wait until it's warmer to do it.

i will keep you informed of how things are going, i have some in city driving to do tonight, so that will help me figure it out

The temp by me is in the 20's and at crusing speed the needle doesnt budge. Plus I'm using the colder thermostate (170F). It means his thermostate has a slight leak. But I agree, the job can probably wait till summer

The temp guage should NOT drop at any speed...highway or city...i had the dropping temp guage problem too at highway speeds but that was also effecting my heating. i just changed the stat and its fixed.
last night i just drove through Michigan, Minnesota and down to Iowa (12 hours)...the outside temperature was 0 to -5 all the way (wind chill made it like -17) and sure enough...the temp guage stayed in the center....
but i did notice my heating got really weak at 75mph and above...the temp guage was still in the center...i stopped at a rest area and the heating came back
....checking out my heating system today

so yesterday i drove about an hour to bloomington mostly 60mph er so, about 10-20 outside, and i was able to feel a heat difference, still warm enough to keep me warm but much cooler than normal
but last night driving around town was very warm kept at 50% er so
my theory is that the thermostat is stuck just partially open, and that the fans are able to come on when necessary
so, the temp doesnt go but so high, cause the fans kick on, and the thermostat doesnt have an ability to raise the temperature
does anyone know if there is a method to change the thermostat without drainin the coolant?
Thanks
Chris

you can also check for thermostat leakage by checking the temperature of the pipes going into the heater core, coming out of the heater core and the main pipe goign into the radiator...
the differences in temperature or lack of it may give u a better picture.
