    HVAC issues - air isn't blowing from ANY location

    Ran into an odd issue last weekend while on a 300 mile trip. Started out everything was good, then I noticed that the air coming from the vents (was running AC as it was warm outside) was coming out very slowly. I start paying attention and after another 10 minutes it wasn't coming out at all...

    Coolant temp sensor - what is a good replacement?

    Howdy guys - I was replacing exhaust manifold gaskets tonight and managed to tear the wire off of the temp sensor in the driver's side head. I've already soldered it together once, which was a real pain. Anyone know a good replacement part number? I'm having trouble finding one with a...

    1999 L29 7.4 - which spark plugs for a .050 gap?

    Just like the title says, I'm looking for spark plugs for my '99 K2500 suburban. I've read a lot of different posts with spark plug numbers, but I don't see any that are pre-gapped to .050. Everything I've seen is for the stock .060. Any leads on part numbers?

    Installing filter on power steering system - which way does the fluid flow at the brake booster?

    I'm installing a filter for the power steering system. It is a directional filter and I don't know which way the fluid flows at the hydroboost booster. Can anyone fill me in?

    Exhaust manifold bolt locations - what is behind/around the front most bolt hole on the driver's side head?

    Howdy everyone - I recently had a set of headers installed and the shop managed to strip out the threads on the front most exhaust manifold hole on the driver's side head. I've heard that there are water jackets very close to some of these holes, so I hesitate to drill it out and put a...

    WTB: Working factory radio - late 90s

    Looking for a working factory radio/cassette player to put in my '99. Half the lights are out on mine and I'm hoping that someone has one sitting on a shelf in the garage that they want to get rid of for basically shipping costs. Let me know if you have anything!

    Anyone running angled spark plug wires on a 454? (edited to reflect issue)

    Howdy folks - I managed to burn up two spark plug wires on my 1999 K2500 Suburban with the L29 7.4. I installed headers last spring and put the little heat socks on the plugs that were closest to the headers on the passenger side. The first time I've towed with it was this past weekend and I...

    Big Block 7.4 Exhaust

    Howdy folks - Finally found a set of headers for my '99 K2500 Suburban. I'm trying to decide how to run the exhaust now... I've read quite a few posts, but can't find exactly what I'm looking for. I'm planning to have everything new... high flow cats, flowmaster (probably 40 series)...

    Pacer cab light install

    Howdy folks, I finally pulled the trigger and got a set of cab lights for my '99 3/4 Suburban. I would have liked a GM set, but prices are prohibitive these days. Anyhow, I've looked through all of the cab light posts I can find and haven't seen much about how to wire them through the roof...

    1999 K2500 Suburban - Hydroboost leaking, replace or upgrade?

    Found a pretty significant leak on the hydroboost unit in my '99 3/4 ton Suburban yesterday. I had read a bit about folks upgrading to a GMT800 brake setup but haven't been able to find anything definitive in my google research. Most of what I found is half ton upgrades from vacuum boost...

    1999 K2500 Suburban 7.4 - no crank

    Howdy folks - I put a new battery in the Suburban Saturday morning as the old one was woefully undersized (previous owner cheaped out). Got it installed and she fired up strong. After driving it around all day (probably started it a dozen times) I went out to move it in the driveway and I...

    HT502 compatible with L29 intake etc?

    I've been eyeing the HT502 crate motor for my '99 Suburban... current 454 runs fine, but leaks a bit and has ~185k miles. Would love more juice under the hood and like the idea of a crate motor so that the truck doesn't have to be down for months during a rebuild. I've done a fair amount of...

    ABS light on after getting up to speed

    ABS light came on this weekend and stays on until the truck is turned off. Comes back on after passing a certain speed (stays off when driving through the parking lot, but comes on when I hit the road). I'm thinking wheel speed sensor. How do I verify, and how do I identify which one it is...

    Suburban rear barn door seals

    Rear doors are leaking in heavy rain. I think it is the seal between the doors but I'm having trouble finding a replacement. Where do I look out how do it search? Should I replace all the seals?

    Boost Auto Mirror review

    Howdy folks - I installed some Boost Auto tow mirrors this weekend and figured I'd do a write up for those of y'all who are considering it. For those of you who have already done it, we can compare notes. These went on a 1999 Suburban K2500 and I went with the stage one mirrors (blinkers and...

    Air bag install - best way to remove rivets?

    Howdy folks - I'm getting ready to install a set of Airlift air bags to the rear of my '99 K2500 Suburban. I figured it was going to be a pretty simple install... drill a couple of holes and mount them right up. I took the rear wheels off to knock it out yesterday morning and found I was...

    Rough running 7.4 Vortec

    Howdy folks - I picked up a 1999 Suburban K2500 last week and have been going through it getting her ready to tow my travel trailer. A few days after I got it it started stumbling bad at speed. This weekend I changed the plugs, wires, cap and rotor (cap was a huge PITA to swap out). It is...
