I will also add an external cooler on Saturday. I might look at running a switch to assume control of the fan too. The car must already have a low Tstat becuase during cruising it only gets to the 1/4 temp mark. but in stop/go traffic it raises up to the half way mark. Fans did not cut on, but they likely will not until 210* or something, right? I would like a switch to cut them on at my discretion.
