I have a 1996 Mustang GT 4.6L V8 which has an oil cooler. The oil cooler is leaking out oil so fast when i turn the car on and i do not know what it takes to fix it. Is it just a rubber gasket/seal? do i need a whole new oil cooler? Here is a video of the leak in action. It starts leaking at 12 seconds. Pictures are attached as well.
I wanna say there is a 5/16 " allen head that you can try to tighten up or remove and change the large O ring . If you don't have a large enough allen wrench you can use the head of a bolt and 2 nuts jammed together .
