like the title say my temp gauge barely moves. i replaced the radiator awhile ago. i went from a single core to a dual core. but the gauge still would move. when off and cold the needle sits below the c. and would move a quarter of the way up the gauge. now it barely moves to the other side of the c. i have heard there two sensors the engine temp sensor and another for the gauge.

Would anyone know where these sensors are? and or what else i could try to get a good reading.

What engine do you have? The temp sensors are in different locations, one for the guage the other for the computer.

the sensor your wanting is on the passenger side of the engine block, its not real easy to get to either

It will move when it gets hot.

mine never did, actually overheated once and still read 'C'

He said it worked then he put a larger radiator in it. Unless he knocked the wire off or the sensor happened to go bad he is describing the way my trucks gauge works too.

it has a 302 i should of said that. and it does move when it is low on coolant. the radiator i got has two spots to plug the overflow bottle hose into. so one gets a plug and that tends to go bad and it will leak. plus i get great heat so i think it gets to temp. this past week the gauge has just decided to hardly move. this why i am leaning to a bad sensor

The other hookup is supposed to hook to a tee on the heater hose, to help purge air out of the system. I took it from the junkyard truck I got the radiator from.

Is the engine actually getting warm? Sure the thermostat isn't stuck open?
