Hmm, I have a factory thermostat housing, degas bottle, degas bottle cap, and engine fill cap on order from Tasca. After those are installed the only thing not oem will be the radiator.
The thing that confuses me is the fan doesn't go to high speed until 228-230*. And It's running between 217-224.
Could be the fan actuator....
If gen1; I don't remember your MY....
