Re: Coolant temp. sensor
did you get an answer for this? my 2000 2.5 4cyl had an always-low gauge. I bought a new sensor (gauge sensor) but wasnt the problem. by the way, the wire plug for the coolant sensor will only fit the coolant sensor and not the gauge sensor and vice-versa...
anyway, before installing the new sensor I read several threads that caused me to doubt whether or not I even needed a new gauge sensor. so before I installed the new gauge sensor (and made it so I couldnt return it to the store) I tested the old one by removing it, rehooking the wire, boiling water inside, pouring in a cup, placing the old sensor in cup and, walla....the gauge went to the middle!
that meant my truck had just been running cool all this time (even though the heater worked) and that the thermostat was bad. I replaced it and bingo, gauge works and so does everything else.
