Oil Cooler Leak
Hello friends. I noticed a slight leak between the oil filter housing unit and the oil cooler. There is a rubber o-ring inside the oil cooler. The dealer does not sell the rubber o-ring by itself and the oil cooler is anywhere between $700-$1200 dollars. Does anyone know where I can find/purchase just the o-ring? Thanks!

That combo kit you linked includes a replacement for the factory transmission fluid cooler, which is a bit smaller.

The only real problem is, that original o-ring should never, ever leak, and if it does, it's pretty likely the filter housing assembly 15609-38020 has a manufacturing defect that didn't pop up until now.

Wouldn't this be better suited to replace the oil cooler

I'd start with an oil filter housing o-ring. If it's too big, just slice a little out of it and superglue the ends together. You could also try 90301-67004 as it is the o-ring used for the same purpose on the RC F and GS F engines (and about a thousand other Lexus and Toyota oil coolers). It might be the same as what you need.
The only real problem is, that original o-ring should never, ever leak, and if it does, it's pretty likely the filter housing assembly 15609-38020 has a manufacturing defect that didn't pop up until now.

Thank you for the suggestions gentlemen. I will try lobuxracer's recommendation.

Hi. I haven't done anything yet. Waiting until I change my oil. I'm going to try the gaskets. If that doesn't work, than I will just bite the bullet and buy the oil cooler. Let us know what you plan to do and please give us updates. Thanks.

have to look and see if i still have a photo. The O ring did fit in the ISF and all looks good so far. will check back under the car in a week or 2. There was a decent leak it was very noticeable under when the shields were removed. Hopefully just saved myself a bunch of money right there by not replacing the oil cooler.

Figure I'd post this here in case anyone needs it. Here are gaskets you will need to fix the leaking oil cooler. One is the O-ring for the coolant block to oil filter housing and the other is the washer for the bolt.
