Hey guys my temperature gauge started boucing around between the N and the M on normal. So far I changed the sensor and no change, so then i opened the valve on the crossover and found a rather large air bubble. The only problem with that is that I cant burp all of the air out it keeps building up a bubble with in a day or two. The other thing thats bothering me is I have no visble coolant leak, which is leading me to believe that I may have bad head gaskets and have pressure coming out (not that I would be surprised the car has 127K mi on it). If you guys have any other ideas why it may be doing this please respond.:nonono:
Bouncing temp gauge
- Thread starter MLS

Does your gauge temp sender have one wire or two? The earlier ones have only one and depend on the metal of the crossover tube making good contact to the heads for the ground. It is possible that you are having a ground issue due to corrosion and/or vibration. You should make sure your ground is good first.
^^ Sound advice.
