I didn’t see anything about the Mocal thermostat in that thread, but I might have missed it.

I have the Mocal thermostat on two different cars, and initially was confused by the recommended routing. It operates differently than a factory thermostat. The Mocal does not positively redirect flow when it opens/closes. In the “cold” position, there is a bypass that opens to allow flow from the pre-cooler line to the post-cooler line. There is a diagram that Mocal makes to show the correct routing. Maybe google it or give Mocal or one of their distributors a call.
