So for reference's sake, the Informeter is saying that my max coolant temperature is 98 degrees in my car. That is with a Koyo full alloy radiator to suit a V35. I'm pretty sure that before I cleared it, Dunc's max temp was 103 degrees celcius. Not sure if it helps anyone but just thought I'd add it anyway.
Now to figure out how to get my air cond thermo fan to start working.
