    1994 K1500 Suburban is now 30 years old.

    Here in Washington, once your vehicle turns 30, you can register it as an antique. I save all of my old plates so I had a couple from 1994 off of our old '90 Corsica. So, on Jan 2nd, went down to the courthouse and registered it as an antique. It cost about $50 to do that and I don't have to...

    No power at 7000 feet

    Right now towing (94 k1500) from way up in Blaine WA to Flagsaff AZ. Been many mountain passes and up and down hills. So going from sea level to 7000 feet. as we climed the 383 began losing power and much lower gas mileage, which I know happens. In the old days (w/carburetor) we would just...

    Guage hookup to ignition power 94 k1500

    Just can't find a place to hook up the positive lead of my trans temp guage. Directions say to hook up to an ignition switch location, can't find such location or where it might be. I have been reading electrical diagrams in Chilton's and the main Service Manuals. Not sure where the modules...

    CAN 5.3 TOW 6000 LB TRAVEL TRAILER?

    My 94 Suburban 383 is kind of screwed up even tho only has 24,000 on it. Bent a pushrod, beat up the valve but having trouble finding an intake valve to replace it. So we're looking for another vehicle. A lot of the Burbs or Tahoes have the 5.3. Is that any good for trailer towing?? I...

    Had this stupid knock (maybe piston slap or worse) for a long time. Coming home from camping trip towing travel trailer it really started knocking, luckily it started getting really loud just as we were getting home. Took it to local dealer turns out it was a bent pushrod. No idea how that...

    Radio

    Bought the adaptors to remove the stock radio and cassette and install a regular radio, got a JVC bluetooth radio. It's so darn complicated I still haven't figured things out since I got it in November. Wasn't sure it was working right, seemed like EQ changed everytime I changed function and...

    Alternator charging too much?

    Stupid again. While removing all of the stock radio and cassette components to install a new radio, I did not disconnect the battery right away. After removing the amp/tuner I finally did. As far as I know, I didn't short out any wires except for my LED running lights, but the fuse blew...

    New Radio, how to wire

    Thanks to some folks on here, I discovered there is a kit to replace the radio pod and the cassette and controls. Got it ordered. Once I get it I'll find out what size radio I can buy. Sooooo, what am I going to find behind the radio and cassette for speaker wires???

    FRONT DOOR ADJUSTMENT 94 K1500

    My 27 year old 94 Suburban is finally showing some wear. The driver's door is starting to sag and bumps up over the door latch pin when opening and closing. I can lower the door pin but then the body lines don't line up. Wanted to raise the back of the door somehow by adjusting the hinges but...

    100 DEGREE TEMP, WRECKED ENGINE??

    Just got back from camping at Bend OR with the '94 GMC k1500 Burb in which I installed a 383 stroker in 2019 and its got 13,000 miles on it. We live in Blaine WA so it was a 1000 mile round trip towing a 4500 lb travel trailer. The 383 ran great until Sunday. That day in Northern Oregon and...

    WIPER FLUID WON'T PUMP

    Darn, my wiper fluid pump won't work all of a sudden (yes it has lots of fluid in it). Can't find a fuse for it. Put a multi-meter on it and looks like the power is not getting to the pumps. Any amazing solutions??? or do I have to chase the connections all the way back to the switch which is...

    JACKMAN steel WHEELS FOR 94 BURB

    Wasn't sure where to post this, but this will have to do. Apparently my aluminum wheels are starting to corrode around the stem. Had to have the gasket replaced cause one tire was losing pressure, 10 lbs in a month. I would like to find "Jackman" or wagon wheel type 16" x 7" steel wheels (6...

    Noisy lifters?

    When my 383 was installed about 18 months ago, it kinda sounded like a diesel when first started up with some metallic ticking. i called the engine maufactureer and they thought it was the crankshaft hitting the oil pan cause we didn't pound it out enough for crankshaft clearance. Since the...

    Flaking paint

    Dagnabbit, my beloved, pristine one owner, white 94 k1500 GMC suburban is starting to shed paint in little pieces. I've been touching it up each time some comes off. I assume it'll just keep going based on a lot of the white GMT 400's that you see everyday. Any way of stopping it? I wonder...

    LED flashers

    Wasn't sure where to post this cause its not Audio, but it does have to do with towing since that's what I do with the Burb. I've installed four LED amber turn signal bulbs and have found that with the stock flasher they flash real fast. I got a Grote LED flasher from NAPA and the turn signals...

    Header Wrap???

    Just installed a set of JBA shorty stainless steel headers, sure runs a lot better, smoother running, actually reduced the noisy muffler sound. Got tired of replacing cracked manifolds. I think I probably goofed by not getting ceramic coated headers cause I'll probably get a lot of heat off of...

    4L60E torque converter question, better cooler

    Been drivin' since 1962, but still don't know how automatic transmissions work. Gotta '94 k1500 GMC Burb in which I have installed a 383 stroker (incredible engine!!) Have been towing 5000 lb travel trailer in 4th on level roads. When going up a slight hill it feels like its shifting down but...

    SORT of towing subject

    Just got done with our first mountain pass tow with the new 383 stroker. It's amazing, huge power increase over the 350, charged up the hills and pass mostly in 3rd, 2nd gear on the last climb over Stevens Pass. Had a fully loaded 28' Trail Cruiser and the Suburban weighs 6,000 lbs just...

    Chip for 383 Stroker

    Just installed a 383 stroker in my '94 GMC K1500, has lots of power, tows great, but been told I should get a computer chip to tune it properly. Service engine light comes on when highway cruising so the computer still thinks its a 350 so is probably running lean. The last chip I got was from...

    ECM re-flash

    Not sure where to put this, but is sort of an engine question. I recently installed a 383 stroker to tow a travel trailer. It runs great and has a lot of power. I keep reading that something like the ECM or something like that needs to be updated or "re-flashed? Is that necessary and how do...

    where to hook-up trans temp guage in 94 K1500??

    Just read the thread from Dec 1st regarding hooking up my trans temp gage, but it was for a newer unit than 1994. My fuse box doesn't look the same. Was thinking I'd scotchlock the pink-black wire for 12 volt power. Then gotta find a panel light wire to hook into. Any one done this? I had...

    4L60e and a 383

    3 years ago Bought our '94 GMC k1500 to tow our 28' TrailCruiser that only weighs 5,000 lbs loaded. Was a one owner, always garaged crème puff, however 350 sucked, still had original plugs, wires, cap & rotor at 126,000 miles. Would barely go 65 mph and wouldn't tow till I removed original air...
