My truck has 82,000 miles, I put the coolant filter system on at 54,000 miles. This 15,000 mile coolant filter is the 4th filter.
Looks really good. I will go 25, on the next one.
The 3rd coolant filter was clean like this also. I went 7,000 on that one.
I have the Diesel Site kit. It first came with a baldwin. I use Fleetguard wf-2077, very high quality filter. It is allot better than the baldwin filter.
Water Filter No Additive, WF2077, Fleetguard Cummins
The 1st coolant filter (baldwin) I went 3,000 miles. Same with the 2nd filter, fleetguard.
Here are some pictures of the first filter. I dont have pictures of the 2nd.
contaminents went through the element and setteled on the lower plate.
