Donaldson P554685 Filter (2-Pack) Review

I use this filter in my coolant bypass system in my 6.0 Powerstroke. I had no crashes or leaks. I always check the filter for particulate matter, but couldn't find any. Either it doesn't work or my system is very clean.

It is the same as the kit. We use Donaldson filters for marine diesel, we have never had a problem, unlike cheap WIX, almost two engine room fires in one week due to blown wix gaskets.

I have an antifreeze filter on my 2000 Ford F250 with 7.3 engine and original water pump. When I first installed this the filter was full the first day, the second a week later and now I change them annually and use long life coolant.
