I'm in Texas, where everyone knows it gets hot... From what I read, the Tr6 benefits from having an oil cooler. Various vendors can provide the cooler, hoses and connections, and it looks straightforward. My question is “do I thermostat” in Texas. We will rarely drive the car in very cold weather, so I assumed that having the oil circulate through the cooler all the time will not be a problem. anyone have an opinion based on experience or good empirical data??
