  • 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. Very Nice Machined Piece for Coolant Filter Application! 5 Star Review

    Posted by on Dec 22nd 2017

    I've installed numerous coolant filters over the years on many different trucks using an other style head but came across these on line and have to say the quality and workmanship is excellent specifically for this 2002 Super Duty application!

    Thanks Riff Raff for putting together what is needed for a nice coolant filter addition!

  2. If I could give it a 10 I would have. 5 Star Review

    Clay has really outdone himself here great product through and through. I've installed cheap knock offs that always leak, crappy sinister kits that leak by far this is the best. You get much more than you pay for. The lines are made of super strong continental brand rubber. No need to worry about the lines losing its shape when it gets hot like other brands. Word of warning me being the normal guy I didn't look at the directions when I installed it. The hoses do not have a fitting that allows you to spin the fitting on the opposite side once installed so just beware. Honestly the swivel fittings always end up leaking so I like this one alot better. No leaks no issues with this kit it's a must have for any 7.3 owner. Clay you really outdid yourself here

  6. great work 5 Star Review

    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.

  7. Awesome, easy install 5 Star Review

  8. Great Product 5 Star Review

    Posted by on Aug 14th 2017

    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.
