coolant filter setup question

I've read many of the vehicle specs on here and noticed quite a few have aftermarket coolant filter setups, I'm curious what the reason for this is? What advantages are guys getting from these? Just looking for a little insight.

Because these motors were cast in sand and leach grit into the coolant over time which eventually wears out the seals in the water pump.
If you plan on keeping the truck for any lenght of time it is a good investment.

just ordered one- will install it on my "new motor" when I get it done- added protection. and the sand!! I don't want sand floating around in there acting as a liquid abrasive.

My daily driver is a M1151 HMMWV, desert sand in color, runs on JP8.
My personal diesel? '97 F-350 5-spd, Pyro and boost gauges, Banks intercooler, Banks turbo housing, exhaust, Banks chip. Dual remote by-pass oil filter. Now I am ready to get serious- new build will have new chip, new turbo, big injectors, big oil, big fuel, coolant filter, big lift, big tires, rear disc conversion.... getting rid of the Banks stuff.

There are two different kinds of "sand". So far only the casting sand has been mentioned. The other kind is the precipitate from the supplemental coolant additive (SCA) used in '99-'01 cooling systems.

If you still use green coolant with SCA, then you need a coolant filter to continually filter out the "sand" that's the result of cavitation knocking off small grains of SCA that are stuck to the cylinder walls in the water jacket. Even with the more modern G-05 coolant now recommended by Ford, you'll still get some sand in the cooling system.

International installed a coolant filter in all their trucks with the 7.3L engine. But Ford skrimped on that detail. So if you don't want to flush the "sand" out of your cooling system every coupla years (or replace the water pump regularly), then you need a coolant filter.

You can build your own coolant filter by buying a filter base and filter from almost anywhere, then adding the bits and pieces until you getter done. Or you can buy the whole shebang from DieselSite and save running around all over town to buy parts:

Or if you want to DIY, start with the filter base. Here's one:

My Sierra Blanca (Spanish for White Mountain) in the sig pic was a great pickup for 11.5 years. I sold it several years ago. I drove a hand-me-down 2003 F-150 SuperCrew 4.6L 2V for a while, but it was unacceptable for towing more than a rowboat. Replacement is a 2012 F-150 EcoBoost SuperCrew Lariat that tows my 5,000-pound TT like a dream. Replaced the 2012 with a 2019 F-150 3.5L EcoBoost with max tow.
