I finally got around to installing the coolant filter I bought at the end of last year. I tried to install it when I did my coolant flush in December, but I couldn’t find a plumbing/mounting option I was happy with, so the filter went back on the shelf.

I finally figured out where to mount it last month when I was installing my Home Depot CAI, the bracket fits perfectly on the bumper bracket behind the fog light, and there is plenty of room for hoses to run.

I had heard in passing that the block offered lower coolant pressure than the head, and that there was a coolant port behind the oil filter.

So I had a mounting/plumbing plan that would work, so I waited until I did my oil change today and tackled the install. The first thing I did was drain the coolant. Once that was done I installed the fittings in the block/head.


I used the ½ NPT plug between 5 & 6 in the head, this is where the most pressure and heat exists. I am using 3/8” hose, so the fitting is a ½” MPT x 3/8” barb.






EDIT: I REMOVED THIS FITTING SEE BELOW!!
The fitting in the block is the return, it’s a 18 x1.5 o-ring metric fitting. I then put a 3/8” x 3/8 MPT barb into the o-ring fitting.




I then mounted the filter to the truck, and figured out how to run the hoses. Once that was figured out I removed the filter head and got the fittings tight.






Once that was done I got all the hoses routed. I zip tied and put anti-chaff on where appropriate.








This is all you can see when the wheel well liner is installed.





The filter itself is essentially level with the bottom of the bumper, and well above the valance piece.

This filter should help increase water pump life, and overall cooling system efficiency. I am also expecting it to decrease the pressure in the head by 5 & 6 as well as decrease my coolant temp by a couple degrees when towing.

AH64ID,

I just wanted to say thanks for taking the time to illustrate the coolant filter installation. It is evident that you spent a significant amount of time in the design process. The incorporation of 1/4 turn ball valves at the filter demonstrates your attention to detail. Great job!

I have driven the truck a little since the install. The filter gets warm, I would say about 100-110* (based on how long I can hold it) before the thermostat opens, and about 140* after.

I towed about 20 miles yesterday and the coolant seemed to be a little cooler as well, maybe 1-3*, but time will tell on that.

I decided to do a little plumbing work last night. I moved the return to the heater core return. I don't think I was getting the full flow I could have with it plumbed the way I did. I originally hadn't wanted to run it thru the heater core return becuase the area is small and the fittings are large.. But it was actually quite easy and looks fine.

I used about 8" of 5/8" heater hose, a 1/2" NPT "T", 2 1/2"NPTx 5/8 Barb, and 1 1/2" NPT x 3/8 barb. All in all the swap took about an hour, including the coolant drain/fill.
