  • 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.

    Great fit and finish. Quality made in the USA and that's why I try to buy everything through Riffraff.

  2. Great Quality and Easy Install 5 Star Review

    Have had this on hand for a while, and the weather finally got nice enough to install it. Super easy install, and the parts are all first quality. The most difficult part, as others mentioned, was installing the hose against the power steering bracket - that could use some modification. It is good to see the filtered coolant flowing into the degas bottle.

  3. Quality setup 5 Star Review

    I had this laying in my garage for a month or two, figured I would put it in when I did a coolant flush. I was surprised how easy this was to install and the quality of everything is top notch. Highly recommended.

  4. Great parts and service! 5 Star Review

    With 300k miles on this 7.3, needed a new water pump, so With the help of Riff Raft I replaced the whole system, pump, radiator, hoses, degas bottle, and a great looking Riff Raft coolant filter. I also the tensioner and pulley. Great prices why not make it right!
    Scott is correct about the tightness with the power steering bracket, a slight angled fitting would be nice.
    I have a competitors product on my other 7.3, guess I have to change that one now!!!

  5. Awesome set up 5 Star Review

    Posted by on Dec 20th 2016

    This is a very easy to install set up. I would advice you to see if using the NPT fitting will make the hose tight against the power steering bracket. If so install the NPT on the head unit or just not use it and spin the head unit while you screw it into the water pump and then mount it. I had to change filter first week because I had already caught so much the flow into the Degas bottle was very reduce. I had a bunch of sand and rust in the first filter. Buy extra filters
