    So what did you do with your truck today?

    I used my 6.9 today to pull an Amazon truck out of a muddy and snowy ditch next to the driveway - video below. It's stuck much deeper than it looks in the video. The driver was very happy, and I think the F-250 was, too.

    Radiator mounting screws spinning in place

    Thank you all. I used vicegrips as Nero suggested - it was a pain to get them in there - but it worked. Got the old radiator off and the new one on.

    Radiator mounting screws spinning in place

    I’m trying to remove my old radiator, but 3 of the four mounting screws are spinning in place. It looks like there is a bracket on the back of each one which is supposed to be immobile but which has broken, so that the screws just spin and do not loosen. How can I remove these screws? Here is a...

    Can I Use Universal Coolant in my 6.9?

    Thank you, ttman4 and FrozenMerc. Yes, I have a new radiator in the barn I am planning to put in, to solve my slow coolant leak. When I do that, I will flush all the green coolant and replace with HD Diesel coolant. By the way, the current radiator looks like an original brass radiator; the...

    Can I Use Universal Coolant in my 6.9?

    I always use conventional green coolant in my 6.9, which has a couple of pinhole leaks in the radiator and now needs to be filled. That conventional green is a little hard to find out here, though, and I need to add coolant without making a long trip right now. Is there any reason not to use...

    Hard brake pedal

    So my brakes on my ‘87 6.9 were fine until this morning; now suddenly the brake pedal is hard and riding high and it’s very difficult to stop the truck. Any idea what this could be or how to fix it?

    I have changed my home heating from fuel oil to a heat pump, but I have about 250 gallons of fuel oil left in my tank. Could I use this leftover fuel oil in my 6.9?

    What to do with this fuel filter?

    This fuel filter sits up against the driver’s cab side of the engine compartment of my ‘87 6.9 - what should I do with it, maintenance-wise? Do I need to drain it? If so, how? When should I replace it? From the writing I can see on the filter, it looks like it says to drain it every two oil...
