Hey Modshack. I did my oil cooler install many years ago based on your write-up. It's been working just fine, although sometimes driven hard at the track, temps could still go up high enough to require me to take a break before the session is over. My car is at a shop now and the guy working on it says the cooler should never be installed with the fittings facing down. Is this true?? I'll ask him in more detail when I get there, but over the phone he said it's not right and needs to be corrected so that the fittings face up. I've never heard this before. What do you think??
