Where's the temp sending unit for the guage? I can't find any references to it in the haynes manual I have.

search!

 

Dang, there sure have been alot of these easly solved by searching posts poping up

At least he looked in the Haynes, thats more than some people!

 

rear iron, underneathe the oil cooler/ filter

 

OK, I found the wire, but the unit seems to be hiding from me. Anyone have a good pic of where it's supposed to be?

 

nm, I found it. The sensor is broken off.

 

That *might* splain why it no worky............

 

if your good depending on where it broke you might be able 2 solder it back (sry about the spelling im tired)

 

is it normal that my temp gauge only raises up 1/4th of the way hot? the sensor seems to be okay, and i did replace my thermostat w a dealership one.....

 

That is actually about the normal reading on properly operating cooling system. If the gauge ever starts to get near the 3/4 range, it's too hot for comfort.

 

what colour is the wire the goes to it?

 

That is where mine sits at on the drive home. Cooler day makes it cooler of course. I'm thinking of just redoing the cooling system, raidator, hoses, therm, and maybe the water pump, it seems to be ok though. Someone told me that the PH and coolant was fine so i'm sure something is clogged somewhere or just not enough flow. I should prob get a better oil cooler while i'm at it instead of the beehive.

 

Ditching the beehive made a big difference in the temp gauge on my '83. That setup really sucks, as it runs hot water thru the oil (heater) cooler, then dumps it into the lower radiator hose, to re-enter the engine without making a trip thru the radiator........

 

Well, after 4 hours and a new set of easy-outs, I finally got the old one out. I installed a new sending unit and it works great. Thanks for all of your help.
