Could my temperature sensor be broken? It always stays in the middle. Sometimes, when I leave it outside for a while, and the car heats up, and when I start it during those conditions, the temp. guage drops ALL the way to cold, but then rises back up in a few minutes. When I start the car, though, after letting it sit overnight in my car hole, it is in the same position as it was when I turned it off. Are there any solutions to this?

I was thinking... could I have some air trapped somewhere in the cooling system?

that seems like the way it suppose to operate. when you shut the car off the needle never goes all the way to the cold side. then when you turn it on it goes to the extreme cold side until the car warms up then the needle moves the the normal operating temp.

Mines just stays in one spot most of the time.

Is it a stock Tstat? If it is & you have some time, take it out & then drive the car. If the temp gauge moves, it works.

if you want to know whether or not your gauge is working disconnect the wire on the temperature sender on the right hand side of your engine (assuming it's a 4.6) it's near the radiator hose ...... if you ground-out the wire , the needle should move all the way to the H.....if that's ok and your needle doesn't move normally, might want to replace the sender,......it's like $4

Just a little correction here,the temp sensor is on the left side of the intake if you are looking at it fron the front.I was haveing problems with mine after I put my white face gauges in so I did the test you stated.Tried the right sensor first like you said and nothing,tried the left sensor and Bam,went the whole way to hot,no problems.The problem was that Geno didnt have the gauge cut the whole way down and it was stopping my needle.Works great now.Not a slam on your part I am just trying to get which side it is on straight.
Thanks,
Chris

yeah sorry about that........it was late at night and i don't know what i was thinking. hehe.......just went out to the car.........it's indeed on the LEFT side,........on the right side is the sender to the computer......it tells your EEC what temp. your runnin'. that has a little harness on it w/ two wires and is near the radiator hose........on the LEFT hand side in between the alternator and the intake hose, close to the front of the engine is the temp. sender for your gauge, that has a single wire on it and THAT is when you want to use to test if your gauge works,.......Thanx for the correction LX! don't worry,....i'm flame-proof so i don't mind hearing any input from others :p
