I've heard this so many times. I replaced this gasket with a NAPA brand and it failed the next year with oil dripping down the filter. Had the oil mixed with the antifreeze it would of been bad news. Stick with motorcraft like this part sold by Riffraff! Quality part.

Great OEM kit. Rebuilt my cooler on a 2001 F550 bucket truck. I also installed a new Navistar water pump, hoses, thermo w/ neck, heater core pipe and gasket, sensor and degas bottle which made the Oil Cooler job much easier overall. This was the time to replace the Back Pressure Tube and sensor while I was there. All OEM parts (Can't afford doing twice) and everything fit as it should. Shipping was on time also. Thanks for the great site.

Exactly what i needed to stop the coolant leak on my oil cooler.

Everything was as described and went together good. No leaks after two weeks so far

Correct part for the job. OEM gaskets and O rings worked great as promised.

Worked great, fixed oil leak. Shipped right away and received before the weekend.

Shipped very quickly (as always from Riffraffdeisel.com) and fit perfectly. Nothing to be complained about.

Bought this kit to replace the leaking o-rings. This kit is a perfect fit. No leaks or issues after a week on the truck. Make sure you clean your old oil cooler really good and lube up the o-rings good and it pops back together pretty easy with a ratchet strap and a couple taps with a rubber mallet. Definitely purchasing this kit to do my other 7.3s when the time comes

Great price by an OEM you don’t have to worry about specs you know the parts gonna fit and work as designed
