    Filter should have shut offs on both sides, for changing filter, put them on the block, before the hose. That way, if you blow a hose, they can be closed, isolating the filter, till you fix the hose.

    Since this was the first time I tried this it seemed pretty straightforward. pull the thing out, drop new one in and screw the cap down. When I pulled the filter out fluid started rushing up so I hurried and put new on in and tightened the cap down. Boom. Done.
    I will try to burp that ##### on Monday while she is warming up.
    Thanks for the advice.

    Final Charge coolant seems to be pretty good, decent price. Tractor Supply, some Dealers. Pre mix readily available. I’m told pure is also available, at a cheaper price. Mixed 50/50 with distilled water, you can save a few bucks. Either way, along with a pre charged additive on demand filter, which has layers of additive, sandwich between thin layers of sacrificial metal, as a cheap insurance against corrosion/ pitting. Otherwise, add required amount of pencool or equivalent fleet guard additives and test with test strips. Keep it in the proper range. Cheap insurance, avoids a premature overhaul from pitted liner, or blown head gasket.

    I owned an old International with an ISX for just over 10 years and I knew everything about that truck by the time I got rid of it. I got this truck and didn't know anything about it. I would not be surprised if they did not ever change the coolant filter or the coolant as this truck now has almost 500,000 miles on it.
    Fluids I usually put a priority on.
    I will be looking to get a coolant flush pretty #### soon.
    Thank you for the info.

    Are no shut off valves on The DD series engines For the ones that had a coolant filter. It was a cartridge filter with a spring loaded plunger in the bottom to shut off flow when filter removed.
    From past experience if coolant filter was plugged up and slimy. You will be doing a coolant pump soon. Easy to change not a big deal. Change the coolant filter every 100k and shouldn’t be a issue any more.
    Have you checked the fan clutch to see if it is locking up 100% and not slipping?.
    Do a good flush and then thermostats, and clean the radiator fins and other heat exchangers as well.
