Oil cooler

Does anyone know if the oil cooler from riffraff comes with the o-rings?

The cooler itself doesn't come seals, they need to be purchased separately.

Thanks for the reply, how often does the oil cooler go bad vs just the seals are bad?

It can get clogged up. What is your problem, leaking?

Your o-rings that separate the two fluids in the oil-cooler have failed most likely. Get the OEM o-rings from Riffraff. The job is pretty easy, but it helps to have a helper. You will want to drain coolant, including block plugs, and drain oil. You may want to also flush coolant system to clear out the engine oil. Take you time re-installing oil-cooler so you get gaskets lined up good.

Good luck!

Oil in your coolant reservoir can also be an indication of a gasket leak on one of the oil cooler heads.

As for life-expectancy... each of my three 7.3's ran past the 200K mile mark before needing new o-rings. I've since put nearly 100K on one of them with no further leaks (the other two have been sold, so I can't speak to their durability).

That's funny, Mark, but it's just the same as it's always been with these things... New Shoes and No Socks, New Pants and No Underwear, New Gun and No Ammo, New Hammer and No Nails....etc.
