    radiator swap?

    I was able to install the E250 radiator in my f250, but I had to drill new hole to mount the radiator in the truch and new holes for the shroud. The external size was the same for both radiators. Unfortunately my old radiator was a 4 row and this one is a 3 row. So long term, I am still looking...

The radiator that came with my truck is really rotten. It held water when I got the truck and first started it, but now...

    flywheel attachment bolt sealant?

    I called my local ford truck dealer(25 miles away) and the service guy said it was okay to reuse the flywheel bolts on a non dual mass fw. He looked up the number of the sealant speced in the service manual and said that the high temp RTV silicon would be fine to use. The bolts list for $17.58...

    flywheel attachment bolt sealant?

    I am ready to swap a flexplate for a flywheel. The service manual says to coat the flywheel attachment bolts threads portion with sealant BSA-19-554a. Anyone know what this stuff is? Do I have to go to ford or navistar to get it?

    I am in the process of exchanging engines in my "86 f250. I need to get the fan clutch off on engine and on to the other. I know the clutch is screwed on with reverse threads.

    Changing front axle U-joints

    I just did this repair yesterday. I took my right hub apart to replace the rotor and noticed that the steering knuckle ujoint was sloppy. I pulled the spindle off and separated the right shaft at the sliding joint under the rubber boot. My axle was pretty rusty. I marked both sides of the spline...

    6.9 install questions

    Thanks for the speedy reply. I have a t-19 trans. I have been contemplating changing the rear seal. It doesn't leak at all now, the torque converter in the van was totally dry. I may leave it alone since I can change it by removing the trans mission later. I may regret this decision.

    Any Unimogs out there????

    I've got a unimog. It's great for pulling out stuck wahoo 4X4's that are top heavy with minimal ground clearance at the axles, but a modern diesel pickup is great for pulling a trailer loaded with a unimog over pavement at highway speeds. My mog has 16'' of ground clearance under the...
