Adding coolant filtration to gas engine?

But what about the stuff you cant see?

It's a coolant system, heck nobody cares about the stuff you can see.
Noboby cares.
Nobody.

Flush it every five years and move on.

Seriously though, this is a solution looking for a problem. But the problem doesn't exist.

Your time is better spent trying to get the cat to smile for the pictures. It almost happened here the other day. This is something worth spending time on.

Is this actually turning into a post you cat picture thread?

Because if it is then it's fantastic!!!

I picked up a 1995 Dodge B2500 with a neglected cooling system. After a thermostat, radiator and new coolant the coolant turned red-brown quickly. Draining the coolant it was obvious that there was a lot of rust in the system. After refilling with the same result I'm going to put a filter in the heater circuit and see what I can filter out. I've got a filter base and filters around so this will only cost me a couple 1/2-NPT to 5/8" hose fittings. After I've run it for a while I'll cut the filter open so Imp4 can see.

If you do this you'll be selling yourself short.

Why not just do it right?
How about if you flush the system until it's clear, purge with distilled and refill with some Peak Global.
Then run it for 5 years.
Then drain it and send me pictures.
No filtering, or cutting required!

Your version of doing it right will not get all the sediment out of the block. Doing it right in this case would involve removing the core plugs to flush the water jacket around the bottoms of the cylinders and that is simply not going to happen. My way won't get all the crud out either, but what does circulate will be filtered out.

For some vehicles, as has been discussed here, there is a definite benefit. Actually change "some" to "very few," but there are some examples. With respect to the OP's vehicle, I'm not sure there would be any measurable benefit. It's a great feel good/OCD thing to do, and relatively easy to accomplish on the engine in question, but that's about it. The cooling system in my 4.9 L has never given me problems, aside from a leaking heater core and a failed fan clutch, both of which were very easy fixes and were unrelated to cooling system cleanliness, per se.
