BamaQX402 Posted March 1, 2020 Share Posted March 1, 2020 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? Link to comment Share on other sites More sharing options...
JackFletcher Posted March 2, 2020 Share Posted March 2, 2020 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. Link to comment Share on other sites More sharing options...
BamaQX402 Posted March 2, 2020 Author Share Posted March 2, 2020 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 1 Link to comment Share on other sites More sharing options...
BamaQX402 Posted March 22, 2020 Author Share Posted March 22, 2020 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.
