    1990's GM Diesels

    I am looking for a truck on a budget. The K2500 in my signature was sold 3 years ago when I bought an ecoboost F150 as a main vehicle. I got tired of driving that in traffic and traded it for an SUV. Now I need another truck. I don't want to spend any more than about $3500. It will be run 2-3x...

    5.7 exhaust manifold gasket replacement

    My tbi 5.7 '94 truck has a leaky exhaust manifold gasket. The previous owner did a head gasket replacement about 1.5 years ago and I suppose did not torque the exhaust manifold bolts down enough. Two were loose and causing the leak. I snugged them back up, but it still leaks. Gasket is toast...

    1994 k2500 ground locations

    My truck is having some electrical gremlins. The symptoms lead me to believe bad grounds are causing my issues. Speedometer goes nuts and randomly pegs. When I use turn signals the speedometer will jump around with the turn signals. When I give it throttle sometimes, the speedometer will act...

    1994 AC stuck blowing out of defrost vents

    Got a bit of an issue with my 1994. Occasionally when I start it up (with ac set to blow out of front dash vents), the air will come out of the defrost vents. Actually not much comes out, but you do hear a bunch of air rushing noise coming from that area. Nothing comes out of the vents on the...

    Newly rebuilt 4L80E shifts funny

    I'm looking at buying this truck to fix and sell. Its a '95 K3500 " I believe that there is some type of electrical gremlin, outside the transmission, that is keeping the transmission from operating properly. The truck does run, and moves under it's own power. Sometimes the transmission...

    6.5 block cracks

    I've heard a lot about 6.5 diesel blocks cracking. Was this a problem only in earlier model years or did they re-design the block at some point? I'd like one but prefer my engine block to be crack-free.

    Video - A/C noise from Alternator??

    My 1994 2500 suburban with a 5.7 TBI makes a strange buzzing noise when the AC is on. Only between 800-1000 RPM. Not below or above. Varies with RPM, at the end of the video it gets worse when I crack the throttle slightly by hand. Sounds like it is coming from the alternator, but goes away when...

    Budget 12v air compressor system

    I'm working on a compressed air system for my 1994 Suburban. I'm always lugging one of those 5 gallon air tanks around for inflating tires etc... Viair sells a nice kit for about $400. I'm trying to get similar performance for about half of that. Here are the major parts so far. I'll post...

    1994 5.7L Tuning, MPG

    A few months ago I picked up a 1994 K2500 Suburban 4x4. Curious what kind of MPG you all are getting. I got 12.5 MPG on a recent highway round trip of about 250 miles. I usually set the cruise at 65MPH. Was expecting ~15MPG. (Let me know if this is unrealistic) The truck has new tires...
