Wow interesting and great idea, post a link at Grainger? I have one on the way to STL so I could pick it up and save shipping, I just did a new water pump as the old one I did died after 50K miles, did a good flush last time so just filled the rad with water to wash out and refilled with new green coolant/distilled water. Mixture is only good to +5F so I need to suck some out and add straight antifreeze.
The first post has a link to the filter body already. You'll need to source fittings (Which I found on grainer) to fit the hoses and strainer body. The hex nut that you need to remove is about 1-1/2"... be sure you have a set of pliers or a cresent big enough for this. I have a set of Knipex pliers that I use, and when the system is cold, I only tighten to about 10 lbs-ft. I tried loosening the filter when the engine had been ran to operating temp... I could not loosen that hex for the life of me.
I flushed it twice with prestone, drain and filled about 10 times and then ran water through it with the engine running. Hoses feel fine, but I have no idea how old that stuff is. Heatercore has been backflushed twice already. System should've been clean already. I will be bringing the truck to the stealership for a full coolant flush to see if they get any crud out as well.Have you checked to see that the hoses themselves aren't plugged? Squeeze the hoses under the hood. If they sound like they are filled with 'Cornflakes', replace 'em.
Pour in a can of 'Rad-flush' as per the instructions, then when you run the water through the heating system to flush it, combine that with an air line beside the water flow, from a compressor, with just a slow flow of air. The air will percolate in the system with the water & helps to break down any crud & scale build-up within.
[Picture not posted 'cause HUUUUGGGEEEE] Holy crap! Those are some serious chunks in there. I could see that tearing up the seals & vanes in the water pump over time.
Water pump was replaced after all of that coolant flushing and draining was done. I'm keeping a close eye on my engine temps as I drive.
