I have two Jeeps an XJ and ZJ with 4.0L cast iron block. The XJ I installed a Wix bypass type coolant filter on the return heater hose from the heater core.
Due to the 4.0L engine block not being made from alum. there appears to be more iron and metal build up than normal in coolant and cooling system passages of the radiator and engine block.
Both of my Jeeps the heater core always has coolant flowing through it as there are no heater core coolant valve(s) such as some of the older Jeeps have. Heat is controlled through a blend door.
So I suspect using this type of coolant filter with spin on filter is able to filter finer particles down to the rating of the spin on filters of which most are at around ~25 microns.
The inline coolant filter such as from Champion with a cleanable filter screen isn't able to filter smaller particles because It would cause too much coolant flow restriction.
I e-mailed Champion asking about specs for their inline coolant filtering and was told that he put in a request for filter specs and would get back with me.
His guess looking at the filtering screen he said appears to be 1/32 of inch.
1/32 in. is equal to .0312 in. = .793 mm
0.0311 inches = US Mesh 20 = 840 microns
So a 1/32 in. (mesh 20) screen equals approx. 840 microns
Anyway I'm wondering if anyone has had any experience with the Champion inline coolant filter?

I'm looking at one on eBay for the ZJ 4.0L that runs approx. $62.00 with free shipping.
or I may just find another filter kit such as from Wix for approx. $37.00 and save a few dollars.
The bypass coolant filter, filters a smaller percentage of the coolant over longer periods of time.
