Percolation? Heat soak? Don't drive during summer??

No, its 180 or 190 with me leaning more towards the 190 thermostst. It was one of the first things I replaced with the wp. I have a brand new 180 sitting in the bag though that I may install.

Sorry man, I was actually asking Jpar. If you have a 195, it still shouldn't get to 230 while idling.
