The jiggle valve on my motor is meant to orient the Tstat properly while in the housing . Doubt that’s what’s causing your issue and I strongly believe you have another problem, like the air that’s been mentioned. Always worth making sure items were installed correctly in the first place - and get a QUALITY thermostat, not some AA generic fit piece made out of recycled reynolds wrap. > It really sounds like you’ve got a pinhole leak somewhere in the system. picking up new t stat from lia tommorow. oem is BEEFY compared to the winpy ass AA. got all the air out. takes FOREVER for the thing to open. so f that. oem it is! --- _[View the full topic](https://forums.speedlife.net/t/wtf-engine-coolent-system-question-inside/241160)._
