Hi all,

Anybody know how to successfully bleed air from the Sonett III cooling system?

My temp gauge is fluctuating between normal and almost 2/3 of the way back to cold after it starts to warm up (5 min of driving)
Thinking air in system at the sensor (where is the temp sensor???) and want to try bleeding the system before pulling the stat. If the stat was bad it would go to HOT, not back towards cold, right?

Any help welcome, thanks,

Couple of bleed ports, by the thermostat housing and another one on the heater core, if I remember correctly...

Found heater core bleeder. Never woulda guessed. I do not see any bleeder on/by the stat cover, the manual even shows one but cant find it. Maybe this one got "modified.."
