'79 CJ5, 258 I6, T150 w/Dana20, Dana30 front and AMC20 rear. My first Jeep! I'm looking forward to doing some minor upgrades and restoration while enjoying the ride.
This may seem a little outside of the box for some but I think it's a good idea and wanted to share this in case anyone else is interested.

I found a filter system for the coolant. That's right, for the anti-freeze, engine coolant, water, radiator fluid, ...what ever you call it. Standard type spin on filter just like the oil system but specifically made for the coolant. Some of you that are familiar with diesel trucks may know of these systems already.

My thought was this: when I got my Jeep and put a new radiator in it I figured that would flush out most of the dirt in the coolant. Watching the overflow tube when it heated up showed there is still a little bit of brown in there, but not much. That was the first part. The second thing that got my attention was a problem with my Toyota wagon. The passenger side of the car blows out cool air while the drivers side is nice and hot as it should be with the heater on. The problem is that the guck in the coolant settles to the far side of the heater core. A quick back-flush of the core basically blows it all back into circulation and the heater works like it should.

The simplest solution I could think of was a filter system for the coolant, and now I've found it. This Wix kit says in the service manual "...you can add the protection of a coolant filter to virtually any cooling system."
There are many filters to choose from both for Additive Free coolant and the usual Additive Type coolant.

I'm thinking to put this inline to the heater core. If I could manage it before the intake manifold I would but before the heater core for sure, right on the firewall next to the core outlets.

It's just one more way to keep the inside of your engine clean. Here is the link to the kit on Amazon, and you can find it on the wixfilters.com web site by typing in the part number 24019, and they can give you shops in your area to buy local.

https://www.amazon.com/24019-NAPA-4..._1_3?keywords=wix+24019&qid=1573401375&sr=8-3

In the next post I will add the picture from the wix book at the parts counter of the auto parts store that shows part numbers for all the filters.

Hope this helps some of you out there.

Doing some more looking around I just saw that Summit Racing has a bunch of this stuff including cartridge type filters, not just spin-on. I really had no idea it was such a big thing, I thought I had found something kinda unique. Oh well.
 
I think these are a great idea, but I also think the larger in-line ones might be better for these old rust/gook farms most are running.

When i first got my CJ I had the radiator boiled out and the engine flushed, put it all back together and plugged the radiator as soon as the engine got hot and it puked out a fresh release of brown gook. Part coincidence, part science.

That said, I think the in-line ones for the large hoses will get 100% of the coolant in a shorter amount of time than those in the heater lines.

It also lets you know what you have going on with your coolant / filter status.

Great topic!

I agree about the bigger inline filters getting more stuff quicker but I also see that as a bit more of a pain to change. I'm good with a little at a time, it's much better than nothing at all and once the system is clean it's just a matter of maintaining. With the right upper hose though, that inline does look appealing.
 
Agreed. Certainly want to start with a pretty clean system before adding the big filter I propose on there.

I like the idea as well, the more surface area and extra coolant I have will help keep the motor cooler er
