Post DIY : Oil Cooler O-ring Replacement V35

I recently replaced my oil pan gasket due to a bad leak and was shocked to see oil still dripping ( pretty bad leak ) , upon further investigation saw that the oil came from behind the oil cooler . Did some searching on here and saw this was a common issue with our cars , so I immediately began to search for a DIY and none came up, I called Cerritos Infiniti and they charged $275 for the work , so I decided to do it myself and make a DIY thread .

Tools :
pliers
ratchet 1/2 drive
14mm socket
22mm deep socket
( container ) something to drain the oil / coolant in
paper towels
degreaser
Q-tips


Parts : O-ring part # 21304-JA11A ( paid $16 )

Click the image to open in full size.


Step # 1
Drain oil into container from drain bolt with 14mm socket ( pictured below )


Click the image to open in full size.

Step # 2
Remove oil filter ( pic below )


Click the image to open in full size.

Step # 3
Remove connector bolt with 22mm deep socket ( pic below )


Click the image to open in full size.

Step # 4
Remove lower coolant hose from oil cooler using pliers and let coolant drain into container
Then remove upper hose connected to oil cooler ( oil cooler is free at this point )

Click the image to open in full size.

Step # 5
Clean oil cooler ( mine had a lot of grime and build up )
remove old o-ring


Click the image to open in full size.

Click the image to open in full size.

( how it looks cleaned up )

Click the image to open in full size.

Step # 6
Replace O-ring lubricate top of O-ring with oil


Click the image to open in full size.

Step # 7
Clean mating surface on engine ( where oil cooler bolts on )
NOT PICTURED


Step # 8
Slowly center oil cooler with connecting bolt inside and begin to screw it in
Angled pipe goes to top coolant hose and straight shorter pipe to lower coolant hose
I hand tightened first bolt first, secured hoses in original spots and then used pliers
to pinch clamps on to original location
Torque connector bolt to spec 36ft/lbs


Click the image to open in full size.

Step # 9
Screw oil filter back on
Double check your work
Should look like this


Click the image to open in full size.


Step # 10
Add oil / coolant and check for leaks

Yup Cerritos Infiniti charged that much , being that I needed it right then and there I had no choice . But I did see that you have them much cheaper , I posted a pic with receipt because I knew I was paying $10 more lol

thanks I am glad It is finally done , for some reason Cerritos Infiniti is much more expensive than other dealers further out , maybe location . They sit in a super high traffic area and are always full

Pretty simple and not much skill required for this simple job . Too many oil leak threads

So happy to see this! I've had a bad leak and couldn't figure out where it was coming from! It wasn't from the pan or filter. I figured it was the Oilcooler O ring.

Cool, I'm looking forward to it. I'll be doing all of this myself. Went to the dealer this past week and had my oil change, they said the o-ring for the oil cooler is bad and that's why I'm leaking. They wanted $156 to replace the o-ring. And what do I see when I sign in to driver? A DIY on how to replace the o-ring. =D

Thanks for the great write up and pictures. Really informative and helps a newbie like me a lot.
