Anyone know any tricks to changing the coolant temperature sensor without having to take off the alternator to get to it? i will obviously do this if i have to but i figured id try to see if anyone knows anyways around this.

 

When I changed mine I had to move the alternator out of the way but its only three bolts so might as well do it just to make it easier anyways.

 

Yeahp that what I wound up doing haha. PITA. But on another note, I changed the sensor and the dash still isn't reading any temperature at all. It worked fine and when I changed my ac compressor and started the truck up that's when it stopped working. It worked fine before then. Anyone have any ideas?

 

did you disconnect the battery? if not disconnect battery cut your headlights on for a couple secs and then plug it all back up

 

yeah that didnt do anything either. thinking i have a gremlin in some electrical wiring somewhere from when i did the ac compressor =/

 

could be the cluster itsself. they are known to give fits sometimes, normally its with the oil pressure gauge though.

 

if it worked before, but now it doesn't - look for damage to wiring, connector, etc.

 

There's two different ones. The one next to the ac compressor controls the gauge. The one next to the alternator give the PCM its reading.

 

In 98 that changed. Only one sensor, and the PCM clues in the cluster via the central timer module what temp to show.

 

What about pre 96?
