hi, i have a 96 f150 4.9l...i cant find the coolant temp sensor that controls the dash guage...anyone know where it is? thanks

 

Yeppers, it's the only sensor on the passenger side of the block, it's on the block itself and not the head, jam your arm down the side and grope the block for something and you'll find it.

Note: You may have to literally crawl atop the engine to get to it depending on how tall you are/how long your arms are.

Note of caution: Do this only while the engine is completely cold and has sat for at least an hour or longer, the exhaust pipes get very hot very quick coming off the exhaust manifold.

Extra note: If you can't find it this way, crawl under the truck and look up with a flash light, you should be able to see it on the block from underneath but I'm fairly sure it's unreachable from underneath. It has a little one-wire affair attached to it.

 

thanks....lol do it when its cooled off....i live in the deserts never cooler than 110 here in the summer. ill take a look at it tomorrow

 

Oh trust me 110 degrees and 310 degrees is a world of difference! Just ask me how I know!
But it's a very simple and quick fix, if inconvenient and uncomfortable.

 

ya i realized its not working driving home friday. it was on the "N" on normal and drove home it was 115 outside with the a/c on and i got home it boiled over on me...next is a electric fan setup!
