Part Number:

The Riffraff Diesel coolant filtration system for the Ford 7.3L Powerstroke filters a small amount of coolant with each pass.

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 work 5 Star Review

    Posted by on Sep 10th 2017

    The kit is great quality, very well put together. also found it was great to have a spot to mount the water temp sensor, which i thought i was losing installing this. my only negative feedback which is minor. the temp sensor reads a few degrees cooler mounted further away. and the line the runs from the filter head to the degas bottle could of been a touch shorter. but overall i would recommend this kit.

  3. Great Product 5 Star Review

    Fits and looks great. Just installed it so will have to wait to see how well it performs but it seems to be a great deaign. If it saves water pumps, radiatora, and oil coolers, it is well worth the money in my opinion. Love ordering from this site.

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

  7. Great Quality and Easy Install 5 Star Review

    Posted by on Apr 17th 2017

    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.

  8. Quality setup 5 Star Review

    Posted by on Mar 26th 2017

    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.

  9. 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!!!

  10. 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
