Nissan Motorsports Oil Coolers

BrandonT

Haven't done my first oil change yet (just bought it) so yeah it could be tight, I haven't looked. Good point. Maybe a drain line off the lower fitting? An upper fill hose may add too much complication (or maybe not). If you didn't use it you would still have the disadvantage of the down mount fittings in having to fill the cooler on startup after an oil change, starving the engine for a bit longer. On the other hand it would automatically air purge the cooler similar to a top mount fitting. I don't think people take the air pocket issue as seriously as they should. This is always an issue with exchangers, many industrial exchangers have vents or "burp" lines just to alleviate the problem.
