Ok, I changed my coolant and thermostat and now my coolant guage doesn't work. I checked the wires everything looks ok. Maybe I knocked the guage while removing the therm. housing. Evrrything looks ok though.

What else can I check. Scanguage shows all the proper temps.

Coolant level is fine, I grounded the sending unit, no movement.

 

The sensor that the scanguage uses is a different one than the guage uses.

Try grounding out the wire and see what the guage reads. If it pegs hot then it's most likely working. If it doesn't... either it's bad or the computer in the guage cluster is.

Thanks Rich, I will check that again and post on that later.

 

I was thinking maybe you have an air pocket in the coolant right around the spot of your sensor. It was pretty common on a few cars where they'd just read cold until you got the air bled out.

 

Thanks John I will check it again. No Movement of guage when I jump the sensor to ground either.

ps any relation to Yankee baseball Great and Hall of Famer, Lou Gehrig?

 

OK, it works now. Guess it just needed to be driven some more. Wierd, eh?

Thanks for all the input guys!!! R-F Rocks!!!
