I couldn't find it, but in an earlier thread last year I mentioned that I would post some pics when the time came this spring to change out the TP roll in the Motorguard I'm using as a coolant filter on my 2000 Dodge. It's that time, and I just changed it out and grabbed a couple of photos.

The roll shown in these two pics was installed at the same time as I replaced my water pump last spring and refilled with new coolant and distilled water.

The TP changes at this point don't really catch a whole lot. The really nasty stuff was caught with the first couple of rolls. It does kind of surprise me how much it does filter out of new fresh coolant though.

How does the TP not disintegrate? I thought most TP are designed to break down in the presence of water for the sake of sewers?

Completely different environment. In the Motorguard housing the TP is compressed and under slight pressure from the coolant flow.

In a septic system there's probably also some bacterial metabolic action going on since the TP is organic material.

There are 2 types of TP. One is for septic systems and breaks down very fast and the other is for city systems and is much stronger.

TP tightly wrapped like that and slightly under pressure and compressed in housing wont break down. They been using this TP method since mid 50s. I use TP based one on my truck also. Works great and its cheap. I dont have coolant one but for oil.
