Need help with coolant gasket
Also, for future reference, a wider shot and/or being more specific (saying it was on the driver's side) would be more helpful, and therefore you'll more likely get help.
That's for the oil cooler.
There isn't a "gasket", there's an o-ring. It's likely that the thermo-plastic pipe is also bad.
After you remove the pipe, you must properly clean that area/hole, otherwise the o-ring won't seal. Use acetone and a small brass toothbrush" (Home Depot or Amazon sells them - ).
Fwiw, to find the part, I looked at:

Since I knew it was for the oil cooler, I searched for "oil cooler", and found the part.

Fwiw, in general, I buy DIRECTLY FROM A DEALER WHEN EVER I CAN!
Then again, your time and effort may be worth nothing at all, and you have absolutely nothing better to do than wasting time and money by re-replacing junk or counterfeit parts.

M271 coolant leak at back of engine
3 pipes go bad as well as 1 nipple. See thread above for reference. Change them all out before the next one goes bad on you. Good luck.
