Temp Gauge Needle

[TurboMR2]

My temp gauge needle wont go above 1/4 and sometime jumps slightly around, is this a common problem? Any way to remedy this, also is this why my heat sucks?

could be a bad ground behind your dash. That would possily make the gauge not read properly.

But if your heat does not work then most likely your thermostat is stuck open and your engine is not heating up. Do you get poor fuel economy or does your car run poorly?

I would replace the thermstat. There is a very good chance it is broken or stuck open.

i had this problem. Check your water pump to make sure its still good. Mine was starting to go out so the thermostat would always be open and my temp would never reach normal temp. Finally the pump went out, I replaced it and it works perfectly now, just a little under normal running temperature

check your coolent level, thermostat either stuck open or closed, at 1/4 opp temp the heat should work because thats as hot as mine gets and iv got scorching heat. also check belts, and water pump. and verry unlikley but your heater core could be clogged.

Ok cool Ill replace the T-stat and see if that fixes it. Any chance its the coolant temp sensor or are they pretty reliable?

It should be your T-stat. I had the same problem. I bought my car from down south and it was equipped with a T-stat that made the engine run cooler. I replaced it and now it works fine.

I would start just by checking the connection on the sending unit for temp gauge, they tend to get corroded (spellcheck..) and not function properly, check coolant level of course, and go from there... Good luck
