    1995 k3500 7.4 timing issues

    On a 95 the plug you need to disconnect is under the glove box, not in the engine compartment. I did have this happen before, where unplugging the wire would make the timing steady but plugging it in would make it erratic and backfire. Tried a known good ICM on it and no change, a new...

    Dug into my front suspension today. Now I have a steering knuckle question.

    That is a dust seal to ensure nothing gets in the bearing and causes wear. But it doesn’t seal oil or anything from coming out

    Picture of 1996 4L80 inspection cover

    My 1992 has that same steel cover. Only 4x4s will have the bosses for the strut rods but otherwise fulfill the same purpose

    leaf spring bushing replacement - DIY or have a shop do it

    +1 on getting the bolts out of the spring eyes. If rust isn’t too bad they will come out with a little hammering. In my case I needed to cut both ends of the bolts off with a large cut off wheel between the shackles and the remaining shank would come out with the bushing

    External slave nv4500 value

    The NV4500 always had a synchronized 1st from the start. It has a weighted synchro setup that makes it almost impossible to downshift to 1 but it’s still synchronized. I’m not sure about synchronized reverse, I think the dodge version had it and was added at some point by GM

    TBI big block exhaust manifold brands?

    I did try one of the China ones, they fit fine and do work, the only issue I had was that there was excess casting slag in between the runners that interfered with the heat shields for the plug wire boots, which in turn made it hard to put the spark plugs in. A few minutes with a grinder could...

    Suburban NV4500 swap

    I ordered this from Amazon last year when I did my swap, seems to be the correct stuff and haven’t had any issues after a few thousand miles. I agree the long wait time now is odd

    fog light problem

    Sorry if that note was confusing; based on what I’ve seen in the diagrams, that fuse will be hot if the truck is so equipped, whether it be fog lights, DRLs or both, the power for them runs through that fuse. Also, all trucks shipped to Canada in 1990-up came with DRLs.

    fog light problem

    I think the power for those goes through the “DRL” (daytime running lights) fuse, I’d check that. Beyond that, look at the wiring manual mentioned above to guide you. Hopefully your switch is good, cause they are hard to find and very expensive if you do find one.

    What transmission is in my 1988 3500?

    It was swapped out. The M20 code means the truck had an SM465, which is the descendant of the SM420 and has a granny gear (and is a cast iron case). By your description, what you have now is likely a light duty 5 speed from a GMT400, but they are classified differently based on year, so hard to...

    RCLB K2500, K3500 Differences?

    You cannot easily swap a 2wd frame for 4wd. Suspension mounting points are different, front crossmember different, among several other things. Easier to just find the proper frame. Also, all else being equal, a DRW frame is the exact same as a SRW. Only thing you’d have to do is swap over the...

    Running terribly

    For the distributor, (if going from scratch) the motor should be at TDC of the compression stroke, and the rotor should be pointed at the #1 wire on the cap (normally it roughly aligns with the #1 cylinder but not exactly). Based on your description you most likely have it 180 degrees (1 full...

    Radiator thread size

    That’s supposed to be a drain plug. Not sure if anything else will go in there

    95 w/t 4.3l manual transmission -does 95 year only apply

    NP. Only thing I’ll add is to try and stick with 93-95 if you can find one, there was an internal redesign in 93 that made it more reliable than earlier versions

    95 w/t 4.3l manual transmission -does 95 year only apply

    If you are asking if you can swap a Different year transmission in, the answer is yes. You can substitute an 88-94 manual trans in without issue, the only thing that is different is the shift lever and boot
