    Serpentine belt tension assembly snapped in half

    308,000mi and the original serp belt tensioner assembly broke in half, just above the pulley. WTH? Fortunately it didn't happen during the 1,320mi round trip to the Grand Canyon 2 weekends ago. And... it didn't happen on the return trip to the Grand Canyon this past weekend, where I was...

    Water pump failure destroys radiator

    The water pump shaft sheered off, flush with the front of the pump, while driving on the freeway last night. This sent the radiator fan w/ clutch, pulley, and water pump hub, forward, into my brand new extra-long radiator.......carving a huge section out of the radiator. The spinning fan then...

    Help! Starter not cranking

    1990 'burb w/ 5.7L and 4L60. Always 100% reliable and has never left me stranded. Fired it up tonight and drove 2 miles to the store. Shut it off for about 5min and then attempted to start it and drive away. No starter action at all. Not a click, nothing. I had my daughter bring over a...

    Chirping and squealing serpentine belt

    Thought the water pump bearings were failing today during a drive. Removed the alternator and had it spun in a machine to see if it's bearings were the cause.....nope. Replaced the serp belt tensioner pulley at $22 because it was right in line with where the noise was coming from.....no...

    Upgrade: Installing the longer 2WD 3/4 ton 454 radiator

    I tow in pretty severe conditions, and have made a few modifications to help keep the coolant and transmission temps under control. A couple years ago I upgraded the original small block 3 row radiator to the bigger 4 row version that I saw offered in the 1/2 ton, 454 models. Nice, but I still...

    WTB: 6.2L radiator fan shroud and top panel

    Anyone have a fan shroud and top closing panel for a 6.2L radiator? Same as used on the 2WD 454's that got that 40" long radiator. Or if anyone's going to their local yards, can you keep an eye out and grab 'em for me? Thanks! You can email me directly at: austinado16 at cs dot com

    Failure of under hood mounted Marshall fuel pressure gauge

    Rebuilt my throttle body a couple years ago, installing the adjustable fuel pressure regulator, Marshall fuel pressure gauge right in the fuel line connection at the TBI unit, and one of the thicker spacers to raise the injector pods. While stuck in LA (Los Angeles) freeway traffic, I start...

    Photo of the radiator in a 2WD, 2500 w/ SBC

    Photo of the radiator in a 2WD, 2500 w/ 454 Anyone out there with a 2 wheel drive, 3/4 ton, with a 454, willing to post some good photos of the big, long radiator? I'd also like to see what the driver's side of the core support looks like, in front of the radiator (if different than the...

    Are these overload springs worth installing?

    These are on the local CL for $25. Doesn't show/mention the U-bolts so I'm trying to find out if those are included. Ad says they were on an '85 High Sierra. Would these be worth adding to the 'burb? I already have a much heavier duty spring set, so all I'm looking for is something that...

    Did I just get 16+mpg?

    Just back from a 535mi round trip to the Los Angeles area and it's looking like 16 and change, maybe even into the 17's. I'm a little shocked, but I didn't use the entire tank, and the gauge is still reading about 4 gallons left. What's blowing my mind is that normally I drive the 'burb 55-60...

    Help with installing a CFM-Technologies fuel pressure gauge adapter

    Has anyone installed the fuel pressure gauge adapter that CFM-Tech sells? So far, I'm pretty disappointed in the part and in their non-existent customer service. The one I received had a bunch of metal shavings in it where they drilled their 1/8NPT holes and didn't clean up, and the...

    Any downside to modding the throttle body?

    Getting in the mood to "rebuild" the throttle body. I've seen the mods of: -removing the raised "rim" from around each of the venturi's -install an adjustable fuel pressure regulator -install a fuel pressure gauge at the TB -install a spacer block between the injector pod housing and the TB...

    So sick of aftermarket parts

    Been having a little issue with the engine dying randomly, then not restart, and then for no apparent reason, it'll fire back up and run perfect, and not die again for days, or maybe weeks, or even months. The 'burb isn't our DD, so duplicating the situation with enough regularity that it would...

    PCV valve chatters at idle

    I replaced what was probably the original PCV valve because it had lost it's check-valve/one-way function. Installed a new one (supposedly for my application) from NAPA. It chatters at idle. I don't recall if the old one did this or not. Did I get a POS valve, is this normal for...

    Recommend a distributor

    About 18mos ago I installed an Edelbrock TBI intake manifold. I'd previously had a problem with the original distributor "chirping/squeaking" and rust around the base of the rotor, etc. I'd pumped some Triflow into it, and that seemed to take care of that issue, but the engine had always had a...

    Rough running when cold

    The 'burb is running rough at idle, when cold, and it's progressively getting worse. It's fine once warmed up. A quick check with a timing light, and it's got spark at all 8 plug wires. Wires are brand new AC/Delco. Plugs are brand new AC's. Cap and rotor are a year old, and whatever NAPA...

    Smoke from the a/c heater controls

    Thought I'd post a little write up on an issue I've been having for about a year now. About 18mos ago we were on a long trip to and from Sacramento, towing the popup camper in the heat. Basically 5hrs each way, in 90+ temps, with the front and rear a/c running. Wound up with melted wiring...

    PSA: Ceramic brake pads avoid if you tow

    Thought I'd pass this on, incase it helps someone avoid an oh shit moment.....or worse. Installed a set of ceramic front pads about 7 weeks ago. They've been fine driving the 'burb locally, and just about zero dust, with a nice firm pedal. I was very pleased..........until this past Friday...

    A/C comes on in Vent mode

    :help:This is a new one. The a/c has started to turn on (a/c clutch engages) when the dash controls are in "vent" position. Do I have a failed control assembly? I've had the dash apart quite a few times (instrument bulbs, replacing the flap for defrost/vents control, etc. but I've yet to...

    Ceramic front brake pads, or not?

    I've got some wierd wirrrring/scraping noise coming from left front wheel that goes away with a light touch of the brake pedal. The front semi-metallic pads (the nicest versions NAPA sells) are wearing funny and need to be replaced. Hoses are new and calipers are rebuilts from NAPA that I...

    Center console jump seat found

    Been wanting to install a bench, so our daughter can ride up front, but didn't want to give up the armrests, and headrests of the captain's chairs, both for comfort and safety. So what pops up today on the local CL, brand new, still in the box, and in the correct grey "striped" velour...

    SBC headers for 'burb?

    Is there a header made that'll fit the SBC in my '90 Suburban. If so, are they louder than the cast iron manifolds? Modifications needed to install them, or are they bolt in? Or, can the stock manifolds be improved with some die-grinder love?
