Oil cooler O-ring(s)

Recommended Posts

Just changed oil and found I have an oil cooler leak. Looking at them on eBay I see single as well as a 2pc set. Listed as;

21334-30F0A - Oil Cooler Seal
21304-JK20A - Oil Cooler Seal.
Do I need both, or just the JK20A?

You need both one should be larger and the other should be a smaller. You need to replace the seal and the small O ring that is on the inside of the screw you will be removing.

Thank you! Getting a list of parts together, getting the P1140 code, so gonna replace both valves, plugs, injectors, and power valve screws while I'm in to it.

Anything else I should address or be aware of while the intake is off?

Thanks

An update; I replaced both O-rings, however I probably could have just tightened the bolt. When I went to take it out, I thought my wrench slipped off the bolt because there was no resistance. So it wasn't even tight. No room for a torque wrench, but I did my best educated guess.
