    GMC 2500 454 belt noise

    You know, it might be because it sounds more like a squeaking noise than a squealing noise from a belt now that I think of it. Are A/C compressors know to make noise because the noise does change when I turn the A/C on or off.

    GMC 2500 454 belt noise

    Could be, but I think I remember seeing paperwork from the PO showing it had been replaced. Is there a trick to testing the tension?

    GMC 2500 454 belt noise

    Thanks for your reply! I installed a Gates belt. I had read that they were pretty good quality. I've never heard of Gatorback.

    GMC 2500 454 belt noise

    Looking for suggestions: I replaced the belt on my 1989 GMC 2500 2WD 2500 because it was squealing. Less then 2500 miles later it's at it again. I put a stethoscope on the idlers and didn't hear anything unusual. My question is is there a known issue with the 454's that I should address that...

    Suggestions for headers, exhaust and beyond?

    I'm seriously considering doing some engine work on "The Massive". I going to do a compression check to see the general conditions of the valves and such. From there I'll should have an idea of what's really needed. I know it could use a new rear main seal sooner than later. Anyway, after...

    Again, thanks for all the ideas and suggestions. I owe O'Reilys an apology, as I am a knucklehead. They are not entirely off the hook, because the wires they sold me were defective. However, the main problem with the truck running worse than it did before the wires was I had knocked the vacuum...

    Well, I went to NAPA and got a new set of plugs. Went in just fine. Guess what. Still runs like crap. OK, so now I'm replacing the coil and the ignition module. It's turned into a project. $32 for the coil and $40 for the ignition module. Better safe than sorry so I'll do both. Borg Warner. It's...

    Can I use platinum non-resistive plugs or do I need to stick with the copper resistive plugs?

    Thanks Jims86 I pulled the plugs (all stunk of gas) and put the originals back in. Still runs like poop. The plugs and the wires are going back tomorrow. Wasted a whole afternoon and evening because of the darn O'Reily's junk. No more. They have lost a customer. On a positive note, the original...

    What the heck is going on? I found the bad plug wire. The number four wire had been resting against a tube coming off the exhaust manifold. After I had located the bad plug using the probe, I latched on the the plug hood, and when I pulled the wire snapped in half. Great, right? I go and buy...

    I have a test probe (a HF model with the big aligator clip) so I'll give it a try. Do I just stick the spark plug wire where it enters it's distributor jack?

    Is this a complicated test proceedure?

    Thanks for the replies. I don't see any type of smoke coming out of the back of mine either. Doesn't smell of gas either. I plan on pulling the plugs and checking them first (while the engines cold), then checking the spark on all the plugs on the suspect side. I really hope it's not anything...

    I knew it! In the month I've had my 89 2500 2wd Suburban I've felt something just wasn't right. It sounded like there was an exhaust leak and the power/economy (ha!) wasn't what I thought a 454 would have. I just got done replacing hoses and I took it over to my neighbor who knows a lot more...

    Shop Manual Question

    Quick question on shop manuals: I have a 1989 GMC Suburban 2500; What GM shop manual should I buy (off Ebay) for that year and model? The picture on the cover of the 1989 manuals there have pickups that look to be the next generation of truck.

    Found the gaskets on Rock Auto. $73.00 for the two of them.

    Didn't think to look. I went outside and checked it out and they look good. We don't use much salt out here in Seattle. Now, the barn doors, that's a whole different matter. It looks like this will need a little more than bondo. I'm thinking about using Miracle Paint with...

    Greetings I am the proud owner of a 1989 GMC Suburban. It is the 2500 Trailer model with the 454, factory towing option, 8 lug wheels, and 3.73 rear end. A beast. The SO and I decided to look into getting an RV. After a lot of looking around I decided on a travel trailer. All I had was a Ford...
