Tempature guage doesn't work

My temp. guage doesn't work in my 1987 mazda b2000 truck. Can someone tell me where to look and what to check for. Thank you for any info.

Seriously? 2 Topics for the same thing?

Two topics posted for the same problem that has already been discussed. . . ?



"temperature gauge" gave me 73 hits, some good, some maybe not so helpful.

The really nice thing about this website is that almost all of the problems with these trucks has already been discussed, diagrammed, dialogued about, and dissected. 1987-1993 give or take a couple of years is a pretty small universe of manufacturing years.

The bad thing is that the search button must be really hard to find and figure out for some people.

look under the intake manifold there should be a sensor i had to make a aftermarket one work for me good luck man

another one on the radiator, lower right corner

temp gauge sensor is under the thermostat housing, it's a single one wire pin. Test the wire, put it to ground. The gauge should jump to max. If it does, then it's the sensor. If it doesn't move at all, then it's either a connection to the cluster or the gauge itself.
