Please help: a while ago my therm guage stopped reading. I had the thermostat replaced. It would only read a temp after being on the highway for at least a couple hours, and it would only go about half way up. I then replaced the radiator which was junk I shoulda done a looong time ago. Ok so the car doesnt seem to overheat from what I can "feel" and the fan turns on when it needs to, but what I am having trouble with is trying to find out where on my engine (94 lx coupe sohc fuel inj, manual trans) is the thermo guage wire from my dashboard cluster through the firewall to the engine? In simple terms, where does that wire connect to my engine, and what is the sensor it reads from?
