ok so after the ride I have noticed a couple of things. This time I let the temp get up to 230 and then it quickly shot back down to around 170 and then back up to 230. It did this like a short in the system, not like the coolant had circulated. Pulled back into the driveway and checked the fluid bulb. No change in the fluid level and the lower rad hose is bone cold. All other hoses are hot. I do know the water pump is working because as I accelerate, the air coming from the vents gets warmer and then cooler as I decelerate.
After all this, I unscrewed the coolant bulb cap to relieve the pressure to see if any change in the level occurs. Remembering a few posts about an o-ring that should be around the threads of the cap...I have none. Could I be loosing valuable pressure causing this problem?
But even still, the lower rad hose is cold with a new t-stat and pump.
Not sure if they would be related, but would the A/C refrigerant pressure have anything to do with the fans not coming on at all? Just something I read in an older post from a guy that had almost the exact same issues.
I hope this is the correct place to be posting these questions. As a noob here I'm still trying to figure it all out.
Thank you again.
