    Any tips on getting the spider connector to seat into the upper intake?

    Was so frustrated with mine I gave up the idea of using the new gasket and went ahead and installed the old gasket on the new spider. Think I came pretty close to pulling the studs out of the new spider while trying to pull it up into the cover, that's when I gave up / went ahead and installed...

    GM intake ? GM 10052951 thermostat housing?

    Welcome to the forum. I'd be just speculating, but after looking at some images / info, it appears as though maybe the t-stat housing only has 2 holes for two bolts. 059 Manifold, intake 10052951 - - 060 Stud, hex (3/8-16x1. 24, 3/8-16x. 75)(#1 rh)...

    GVW C1500 and axle weight rating

    Looks like there is quite of bit of info on the subject in the 1990 brochure from GM. https://www.gm.com/content/dam/company/no_search/heritage-archive-docs/vehicle-information-kits/chevrolet-trucks/1990-Chevrolet-Truck.pdf Pages 2, 14, 15, 16 might be a good place to start. I do see a...

    K3500 frame dimensions

    Page 88 has a couple of measurements. Not sure if it helps, but it looks like the height of the frame and width between the rails is listed for the very rear (inside dimensions).

    K3500 frame dimensions

    Welcome to the forum. Guessing the OP has a K 30943. Might be helpful to search the above document for that ,with the space between the K and 30943. That's just a guess though. https://www.gmupfitter.com/light-duty-vehicles/light-duty-prior-to-2013/ Best of luck.

    Lower radiator hose???

    Mine is a 1999 5.7 (bought it new) and from what I remember, when working on it over the years for things such as water pump / steering parts etc, that lower was always a pain to deal with. As can be seen in the pic above, even with electric fans which have their own shroud, it still contacts...

    After head gasket change, no start. C1500

    Op mentioned a relearn which I think is a passlock term, that relearn (leaving the key in the run position for extended periods of time) process is probably counter productive in the case of trying to get the starter to turn, discharging the battery isn't going to help solve that. FWIW 1998...

    Anyone know what I need to get these ines back up where they should be.

    I don't have a suburban and am guessing the OP has a 1994 judging by previous posts. Looks like some straps may be missing or broken in your pics, when comparing to these here parts diagrams...

    Dash swap 98

    I"d guess that even if a 1998 or later evo/passlock module can be found or is already installed, a 1997 wire harness would still be missing three wires. At the connector for the module in a 1997 there should only be 10 wires, a 1998 and later should have 13 wires (the three added wires for 1998...

    Rough country 6" lift extra parts? Problems? (2500/3500)

    I'd guess the large bracket you have pictured there may replace part number 6 here. This may be a pic of the original part in place. Above images are from this gmt400 thread here. https://www.gmt400.com/threads/k2500-ccsb-carrier-bearing-s.63735/

    How rare is this combo?

    Mine is a 1999 model year, the dealer stored it (and 2 others) way in the back of the lot as if nobody really wanted them. Battery was totally dead upon first inspection. Sticker listed the price around 37k, they let it go for just under 30K. Guess they might have had a hard time selling...

    Fuel gauge needle vibrating

    Wonder if you replaced the cluster with a new or used one. Think the issue may be pretty common. My fuel gauge does the hummingbird thing (flutters at the correct fuel level). Never really bothered me enough to fix or replace it (yet). This is a good read here, with pics, links, video and...

    Column shift wire to gauge cluster routing

    Help..1997 chevrolet c/k 3500

    Think this may be a 1999 Tahoe underhood fuse center. It looks like the same things are missing there. Not sure about the model year on this close up, but it shows some terminals are missing where there are no fuses. Pretty certain a 1997 truck equipped with the factory aux cooling fan...

    Headlight Switch

    The way I did it was (since removing the DRL fuse kills the DRL lights), I ran some wire (using fuse taps) from where the fuse originally was (side of the dashboard) to a toggle switch, also installed a separate inline fuse to protect the circuit. Everything is hidden well, unless someone...
