Sinister Diesel Coolant Filtration System for Ford 2003-2007 F-250, F-350, & Excursion 6.0L Diesel with All Hardware – No Part Removal or Drilling Required For Filter - Easy Installation

Perfect kit. Parts are very well made and machined. Very easy to install. Did a full flush then added in this kit. Coolant flows clear and I don't see any deposits in the overflow tank. After this and the flush, my coolant and oil temps are mush more in sync than where they were. While I doubt this will cure all ails, its a great piece in making your powerstroke a workhorse for years to come.

Inexpensive insurance for your 6.0!! Keeps your oil cooler and egr cooler (if you still have it) from plugging up with silicates and blowing your head gaskets. Added bonus is it looks good under the hood! Remember to get a few extra filters your going to need them. You use up a couple pretty quick,after that change the filter about every oil change or when the filter doesn't get hot( it's plugged with stuff). EASY install with good directions. If you still have a factory degas bottle cap do yourself a favor and get a 5 buck stant 16psi cap also. The factory caps never holds pressure and boils your coolant! That is why the coolant broke down in the first place. Happy day

Well made and great looking product. Install instructions are easy to read as long as you know your way around your engine bay. The Blue really pops under the hood like all Sinister products.The XDP version actually is probably the better pick though. Instead of having to cut two lines, you only have to cut the heater hose. The other line comes already attached to the T. You just remove the existing hose and use the same clamps. One less spot to spring a leak.If Sinister were to change that one thing this product would be 5 stars all day. As for filtering this thing works great. Removed my first filter after 500 miles and it was filled with rust particles and casting sand. Replaced with Napa filter 4070. Will replace after another 1000 miles.

Excellent product, and easy to install. I bought this to help filter my coolant after having to replace a oil cooler. I didn't want to have to go through that fiasco again. I flushed and flushed and flushed and flushed the system to clear out any more contaminants. I was shocked that after only five hundred miles this filter had collected all kinds of sandy particulate matter. If you buy this system, expect it to work, and expect to change filters at 500 miles, 1,000 miles, 2,000 miles, and then about every 3,000 to 5,000 miles to keep your system nice and clean. I would 1000% recommend this product.

I have replaced the filter to see if it’s a bad filter that the sent me and it’s not ig it keeps leaking from the filter I filled the filter yup lubed the O-ring and it still leakes I am tired of this can’t keep coolant in my truck cause it leaks it out so bad

Kit came before it was expected and was well packaged. The package list stated that there was supposed to be a roll of Teflon tape but it was not in the package. Had plenty in the garage so this was not big deal but might slow up the install for someone that had none available. Took approx. 30 minutes from start to finish to install and fit perfectly. Would recommend this kit to other 6.0 owners that want a little extra piece of mind that the coolant is being filtered and not clogging the EGR cooler with crud.

this is a good product, no leaks, but after about 20,000 miles one of the knobs fell off. They are just held on with small screws. the valve still works, just need pliers. If I had to do it over, I'd buy the mishimoto kit.

This is a complete kit that has everything you need including the mounting bracket, filter mount, shut off valves and hose clamps. I don’t know why they don’t show everything in the picture. Everything was good quality, I especially like that the tee connections are metal and not plastic. It also included easy to follow instructions with pictures.
