The radiator is handicapped by the stock thermostat. I installed a Reische 170 degree thermostat (and a tune to make sure the fans turn on earlier) and bam HUGE improvement.
I would use the Reische if I were you. The Evenflo (the one I assume you got) isn't any good and has issues. I think there is another 160 thermostat brand but the Reische is more than good enough and the perfect temperature.
LOL, there is nothing to keep in check. If your engine is running hotter than it should be then there is a problem that needs to be addressed. Installing a lower thermostat might bandaid it, but it won't resolve the issue. If you install a lower thermostat, then do it because you particularly want the CHT lower. But stock, there is nothing to be improved or kept in check. The engine was designed to run at the temperatures you are seeing. I drive mine all day in 90+ temps including making several stops while the engine is running for about a minute at a time. My CHTs stay in the 220s. And that is fine. Most of the time I don't even pay attention to it. If something goes wrong, you'll know way before the engine gets damaged. If you don't then the car will let you know. You're fine. I wouldn't worry about it one bit. And if something does go wrong, take it to the dealership and have warranty work done.
Yea if done for performance reasons or to keep the temps done during extended track use then it is fine. But I thought he was saying he wanted to get it because he was worried about the temps or something.
Oh if that is the case I wouldn't worry then.
