Lumina '92 3.1L Euro: Temp Gauge running Hot, but engine not
Hi Everyone !
Sorry for my english, English isn't my first language.
I have a Chevy lumina Euro 3.1l from '92.
I have a little problem with it:
My temp gauge, in the dashbord, says the engine is getting to hot.
When the car is in idle, the temp gauge will just keep rising to around 190-200 F, when driving 2-3 miles, it will keep going up to 260 F and the heat indicator will start flashing.
When we measure the engine's temperatur with a IR termometer at the thermostat house it says 180 F, so the thermostat and the fans work just fine. (the fans kick in when getting over 180)
We have tryed replace the temp sensor twice, but getting the same result/problem.
The problem just came out of nowhere.
Does anyone have a clue to what we could try?
Thank in advance
Thomas

Down in the bottom left corner, the silver cap above the sticker? (It's not an actual picture of my car)

that should work.
Do you have a brass type fitting with screw on top like this? Open it up and fill until coolant trickles out. If the temp is still spiking, open this carefully.. it may spray out fast as it is hot and may burn you if your not careful.
