well i didnt realize u had a bleeder valve on the intake, we just installed the thermostat and replaced the antifreeze so im starting to belive that i just have air in the system... i hope.... just hit 43000 miles

 

well had the system bleed today and nothing.... starting to think it may be the thermostat i put in, the gauge doest sit at the same place and moves alot more frequent now... and even without a load where the old thermostat moved with a load behind the truck...about to pull my freakin hair out!!!!!! got to be something simple because the truck doesnt run hot, the damn gauge wont stop moving and it drives me crazy!!!!
