  • Image 1
Part Number:

The Riffraff Diesel coolant filtration system for the Ford 7.3L Powerstroke filters a small amount of coolant with each pass. The Donaldson spin on the filter makes it easy and inexpensive to change coolant as often as you need. Plus, the filters also remove all solid particles. Typically you will use three filters in the first nine months. Once the initial nine months has passed, you will only need to change the filter once a year.

  1. Great Product 5 Star Review

    Posted by on Sep 5th 2018

    Impressed with the quality of the hoses compared to other kits of similar price. The hose with the "T" at the end was delivered slightly damaged(part of the T was crushed), I received a replacement shortly after with no problems at all. No leaks on first try. Flushed system with Rotella ELC after I bought the truck, looking forward to the added protection.

  2. Works Great 5 Star Review

    Everything works like it should. Very happy!

  3. Good quality but I made a modification to ease future cooling system maintenance 4 Star Review

    Great product. I offer a couple of tips from my install.

    First, you really must crank the NPT shutoff valve fittings much farther into the filter head than feels right and use plenty of thread sealer or eventually they will leak. They must stop turning/bottom out when using a fair (not gorilla) amount of tightening force before they will properly seal.

    Second, I opted to use a length of heater hose clamped to two standard beaded hose fittings (not barbed fittings) threaded into the female NPT outlet in the thermostat housing neck and the shutoff valve inlet entering the filter head. This allows the hose to be easily removed and replaced at either the water pump outlet and/or filter head without having to disturb any NPT fittings in the process. Seemed to make sense since NPT fittings don't necessarily like to be removed and retorqued.

  4. Quick and easy install.. 5 Star Review

    While I was flushing my radiator to change the coolant I found there was alot of sediment floating around in the radiator. This kit went on quick and easy with no surprises. Another high quality product.

    High quality

  7. Only one issue 4 Star Review

    Posted by on May 16th 2018

    Overall nice kit. The only issue I have is that the line from the water pump to the filter housing is a pain to hook up. A swivel would really help make this a five star product. Other than that, very great product.

  8. Quality Parts 5 Star Review

    Easy to install and has everything you need. Another quality product from Riffraff! One improvement would be to have the side of the hose that runs to the water pump be able to swivel to make installation easier.

  9. Looks good, well put together kit. 4 Star Review

    Posted by on Mar 12th 2018

    Kit comes complete with everything you need, down to the thread sealant. Craftsmanship of the parts is stellar. Only thing keeping me from giving 5 stars is A) then recommend replacing the coolant filter frequently for the first 6 month. So would have been nice to include a couple extra filters in the kit so you don’t forget to purchase separately or have to keep going back to purchase. B) which the mounting on the filter adapter had some adjustability, as I had some issues with clearance on the OEM Battery box. Other then that, this kit is great and priced right

  10. Great Product. 5 Star Review

    Posted by on Feb 28th 2018

    I put this on my 7.3 Excursion while I was doing oil cooler O-rings. Figured since I had the system open, was a good time. Installation went smooth. I had an issue where the filter was way too close to the factory battery box. Only needed about another 1/2" of clearance. Found out it was hit in the front at one point. Things probably weren't 100% where the should be. I had to cut a slot in the battery box for filter to fit. Not riff raffs Fault. All good and works great. Great customer service as well!!
