What would cause my temp gauge to float? One second its at normal temp then just drops a quarter if the way down then goes right back to normal.

there should be a water sensor/sending unit on the intake somewhere in the water passage.

for air you can usually just runn it for a while with the cap off and it should burp out. then you may need to add coolant accordingly.
i would think he air is most likely the problem. whenever an air pocket gets by the sensor it is causing faulty readings.

Yup, air bubbles or a possible broken sending unit wire are the most likely causes. :good:

Sounds like air, I had this issue 2 hours ago, with engine cold, open rad cap, and rev engine a few hundred RPMs higher than idle, hold it there till the temp gauge settle. Add coolant/water as needed Good luck

Did this twice today and it is better now. Still floats a little but not nearly as much as it did.

Going to do it again tomorrow and see if that takes care of it. Hopefully it does.

I'll try jacking it up and see if it helps get that little bit out.

I let it run for 30-45 minutes both times giving it gas every 5-10 minutes. Hopefully there is still a small bubble in there I can get out and not a sensor/sending unit problem.
