my temp gauge in my 1992 ford f150 2wd 4.9 5 speed is not working...

it does not go up to the "NORMAL" range and it sits right above the C

im thinking the temp sensor is not working and i am thinking about replacing it...

before i go on..i have searched many threads on here and i still cant find the answer to this question...so i am now asking for some help...

im thinking my sensor is dead and want to replace it its only like 25$ but i dont want to spend on it if its not that...

thanks for your help

 

I have had luck just pulling it out and cleaning it off with steel wool. They get a nasty build up from coolant over the years.

 

Its not the temp sensor that works the gauge it's the temp switch or some call it a sending unit. Its the one wire unit on the side of the engine not the two wire one by the thermostat that's the sensor.

 

55: has taking it out and cleaning it up worked for the gauge to function? has having it dirty made the gauge not function?..thanks

hawk: so your saying i should check the "sending unit" is that the one thats about 2" maybe 3" back and to the left of where the temp sensor is...thanks

 

$25???? It should be about $10 at the most and you should be able to replace it easily by yourself without creating a mess if your $25 is including someone's labor. You can get one from Napa for about $6 if my memory serves me correctly.

Also, are you aware that there are 2 different temperature sensors? One to send the computer a signal and one to control the gauge.

 

Put an analog guage they work better. thats what i did and it has help me keep a better idea of the working condition of my 87 f150. id also did the oil guage and soon after when my oil pump went out i knew before it could kill my motor. New oil pump is in and truck is running fine!

 

yea the temp sensor at autozone is like 20$..

ok yea ive read that ther are two of them...

can you shoot me a pic or a part number for the one that will work for the gauge...thanks!

 

what do you mean by analog guage sir? excuse my incompetence

 

Part Number: TU25

Look it up on AZ's site by the part number.

 

very nice! thanks sir..just checked it out...10$ and it says that this unit is what sends the info the gauge in the cluster! im buying it tonight and replacing it...
