Coolant filter?

[desert-rat]

Your thoughts. Anyone done it? I'm thinking if I did, I'd do it like the picture here

You could do it thru the heater plumbing as well.
Many diesel truck run them.
Pitting of the liners

Interesting. My system was in really bad shape. I ran a few cycles of water and flush to clean. Then cooant. Still pretty rusty. More flush. Then new coolant and finally a reasonably clean system. I would buy the filter and then a inexpensive remote oil filter mount to match filter and plumb into heater hose. Less chance of overheat and way under 100 bucks if you really think it is needed.

That would save a heater core....

The stuff I flushed out of the core was unbelievable. It literally took hours to get the water to flow clear. After initial hose flush, I think I used Preston flush or some other basic snake oil. It worked well and I had to hose flush for another hour or so. I think a PO had poured a few bottles of stop leak in trying to plug a head gasket leak. I ended up pulling the motor shortly after and the goo and rust in the water chamber was frightening. I could not believe an engine could run in that condition.

They've been around since the 30's or maybe earlier. Many poor folk back in the day couldn't afford anti-freeze. Come winter they would drain the water and not drive the vehicle until spring or if they needed to drive somewhere the would start the engine and then add water. They would keep the engine running till they were home again, where the water was drained back out. Putting a screen in to keep the rust and dirt out of the radiator was cheap insurance for the radiator. No one back then put distilled water in the radiator. Water from the well, or horse trough, or the ditch next to the road was good enough.

They're still pretty popular with the pre-war restoration crowd. Old engines that don't get run a lot and when an engine sits over time the anti- freeze can start to separate from the water and you get rust in the lower parts of the block. Then that rust ends up in the radiator. The screen captures the biggest pieces of rust.
