Ever think of going about it a little more simple?

Diesel engines have coolant filters to keep the coolant clean, as well as preventing cavitation erosion... Just add an aftermarket diesel engine coolant filter and housing to your system, tapping into the heater hoses.

Baldwin CFB5000

Fleetguard makes a similar (and much cheaper) filter base, PN FG - 204163S, list price is $15.72.

I gave the link for the Baldwin because it is the only one I could find online in short order.

You would then use the filter of your choice, like the Fleetguard WF-2070, which lists for $10.36.

You just added a high quality coolant filtration system on your rig for less than $30. <img src="/forums/images/graemlins/kewl.gif" alt="" />
