So the only thing I really need to know is... Do I change the oil in the oil cooler? Like the title says.

 

it would be a good idea. i doubt most people do.

 

Its a new build, well 500 miles ago and the oil cooler was cleaned and flow tested when I replaced the motor. But I was figuring it was prolly a good idea too.

 

You can. Dropping the oil cooler isn't too hard. Just undo the mounts, break the cooler lines loose, and try not to get coated in oil.

I just took mine out over the weekend to put some new lines in, and it was the easy part of the job. Of course, getting all of the oil out of it is actually fairly time consuming. It really gets trapped in the passageways.

 

I said f it... if the oil cooler had a bunch of miles on it and old oil I would care, but since it was cleaned and flow tested I am not going to care that much... maybe after this year and I do all new fluids next year. Car runs cool as crap right now anyways and oil pressure is great.
