FEL-PRO ES 73012 Engine Oil Cooler Adapter Seal Set for Jeep Wrangler

I bought these o-rings to use on a metal replacement part for a Town and country.While they seem like they are great quality they ended up being not thick enough to use and where slightly over sized.So I used the ones that came with the new part instead and I guess I'll keep these o-rings as a spare.

Ordered a replacement Pentastar oil cooler by MNJWS here on Amazon, read my very detailed review there for a discussion on the part and step by step instructions on how to replace the cooler.In short my thinking is that there are not a lot of aftermarket companies building this part and due to its complexities and importance in the powertrain, the cooler can only be made so cheaply. Many reviewers cited the rubber seals on several aftermarket coolers as failing prematurely. Since the cooler sits atop the hot engine block, the gaskets spend their life getting cooked on every surface. Fel-Pro is the only company selling silicone blended gaskets for Pentastar applications and it is my hope that the silicone blended rubber can endure better than the regular rubber.When you install these gaskets on the cooler, they will not appear to be round. This is normal as the rings will self-adjust upon installation. Prior to installation, put a dab of clean motor oil on the black gasket directly under the filter housing, and the two blue ones that follow in the line to the right. Leave the last two dry (these are coolant channels).When installing, align the filter side to its port first, then the rest of the assembley. Then press the cooler firmly with two hands (on filter housing and metal fin edge) STRAIGHT DOWN. You should hear and audible click whine the filter is seated, and there should be very little play when shaken and unbolted. Bolt to spec using caty corner technique. Failure to use care or technique when reinstalling the cooler will cause you to damage either a gasket or the plastic port mates on the cooler or the engine block itself (yes, where the flow ports on this thing attach to on the aluminum engine block is fitted with plastic. Bleeping Chrysler, man).Silicone can withstand sustained temps of up to 400 degrees F. Powertrain fluids in the Pentastar should not exceed 200 deg F for any sustained reason. I thing Fel-Pro has a good product here. Time will be the best judge as usual and I'll update regularly.

If your Jeep is leaking from the oil cooler, don't bother trying to replace the gaskets on the factory unit. The housing could be cracked and the oil cooler has SIX gaskets but you can only replace 5 of them. Just replace the entire housing assembly and purchase this gasket set (and felpro intake gaskets - MS 97204 for my 2014 JK).These are far superior to any gasket pre-installed on the unit you'll be purchasing. Resist the temptation to skip these. When you install these, they will look non-circular but that's because the nubs on the gaskets. Just ensure you have them seated properly and you should be fine.

Made the leak even worse. Had a leak of only oil sitting on top by the oil cooler and used these to replace the old seals. Now I have milky oil when I performed an oil change.

These last much better than OEM, fit well also.

Right fit perfect for the application. Polite and helpful staff. Will definitely buy from again.

Product appears to be a heavier duty design than the originals I removed. At 116K miles the original gaskets were completely flattened out and the oil pump o-ring was especially hard. The new gaskets are thicker with a double ribbed mating surface. They are akward to install as they are slippery and try to pop out.

I will recommended

Producto regular, bienen de diferente grosor, las combine con las que traía el nuevo enfriador. Funcionaron bien.

Quality material and made with ridges to hold them in place during assembly.

Good quality gaskets. Direct and precise fit.

I bought this to stop the oil leak on the top of my 3.6l pentastar engine in my 2014 Ram C/V . 4 of the seals fit perfectly, the largest seal was too thick. I ended up using a hydraulic O-rings and backup rings instead. The good thing is it no longer leaks.
