Making a Coolant Filter for 81 300sd

I am flushing the motor this week and would like some feedback of the best way to add a coolant filter for the inlet going into the radiator so all stuff that may break lose will be caught before it goes into the radiator... here is what i found so far.... i will keep looking for a larger hose fitting but this is it so far

Fleetguard 204163S Coolant Filter Base -BUILD Your Own Coolant Filter
or

Baldwin CFB5000 Coolant Filter Base

both are around 30 bucks plus a filter... i thought of doing a clear can filter with a lining like our clear fuel filters.....

Since the Coolant Filter is not a Full Flow Filter it is not going to stop what you are worried about; that is stuff breaking loose after the Flush and plugging your Radiator Core.
Since it is sort of bypass type Filter it would eventually Filter all of the Coolant. But, unlike an Oil Bypass Filter that also has all the Oil going through a Full Flow Filter stuff is still going to get into vital areas before it passes through the Bypass Coolant Filter.

And, if you did something to Filter the Full Flow to the Radiator (like stuffing some Aluminum Screen into the Radiator Hose) when the Filter gets plugged you would overheat.

However, it could be a long term benefit because the Filters often have an additive replacement in them.

I'd think a simple mesh filter would do a good job with this.

Nice info find!

The Clear Plastic Tubing of the GANO Filters in the Article is a good idea! Otherwise you are not going to know if it plugging up until you are overheating.

Once overheating begins you are stuck having to remove the Filter to clean it; possibly on the Road. At least if you can see the stuff inside (assuming you check it) you have a to catch the issue before you overheat.

It seems like what is needed is something constructed similar to a Fuel Water Separator.

The Coolant would enter what amounts to an expansion area as it does on many Fuel Water Separators; that slows down the velocity of the Coolant; heavy particles fall to the bottom while the clean Coolant continues upwards through a screen and on to the radiator.
A Glass Bowel at the bottom would allow for observation and drainage.

Boy they are expensive, close to $50 each.
