    Vent Window rubber replacement or replace?

    I need to rebuild mine. Once everything is apart the body shop said he will paint them. Then I can reassemble. I watched some videos and it looks easy enough. I guess I will find out soon.

    '87 GMC Suburban V1500 1/2 ton - replacing leaf springs

    I bought springs for my V3500 from a local spring shop. They asked me a few questions and I ended up with stock springs. A 1 ton truck rides hard enough I did not want HD springs for the front or rear. Since this truck has been in my family since 1988 and I have hauled or towed with it many...

    Mirror replacement

    PM me. I am restoring my 1987 GMC V3500 and it had those mirrors. I am replacing them with the "normal" style mirrors. I can sell you my pair. The left mirror glass is broken but otherwise they are good to go. PM me if interested.

    454 long block replacement and associated sensor issues

    The coolant temp sensor you showed with the button type fitting takes a spade connector. It slides on sideways so on with a standard type will also work. The 8th digit of your VIN will tell you what the original engine was supposed to be. "N" is a throttle body injected 7.4L and a "W" is for...

    1986 Automatic Transmission Leak

    Thanks for the tip on Lube Locker for gaskets. Cork is good for bulletin boards but not gaskets unless you like leaks. I have used rubber with a metal insert that works well. You actually can reuse it a couple times. I think Moroso is one place that sells them. If it were me, I would clean off...

    Smoking Ground Wire

    The small ground was carrying all the current. The big cable is your problem. Not connected, bad connection , etc. Perform a voltage drop test and diagnose the issue instead of guessing.

    Overheating 87 TBI

    You should give your system a nice flush. Get some Citric Acid powder. Mix 1lb to 5 qts of warm water. I would mix up 2lbs worth. 1. Drain cooling system 2 Remove thermostat 3. Fill cooling system with the citric acid mixture 4. run engine for at least 15mins. 1 hour is best. 5. drain the...

    Whats your opinion these welders?

    I have the Hobart 210MVP. I looked at Miller and Lincoln too. The Hobart is a no frills machine but still good and is made by Miller. This welder will do 120v welding if that is what you need. It has a transformer not an inverter. The downside is it is much heaver than an inverter model. I am...

    POR 15 equivalents?

    In the past I have used POR15 but was not super happy. This was back in the late 80s when the first started and it peeled. Since that time they have added cleaner, prep and other products to their lineup. Back then they only had the black rust coating. A few years ago I started to repair a...

    Need source for exhaust 1987 V3500 4wd 7.4L N

    I am trying to locate a premade exhaust for my truck. It is in the restoration shop and would love to just buy a bolt on set up. I am OK with stock exhaust or a true dual system. I just want it to fit. Does anyone know of a source? My truck is a 1987 GMC V3500 4WD 7.4L N, single cab, 8 foot...

    1987 454 TBI stalls at idle after a short time

    I did not "just plug it in". My laptop does not have a CD drive, I bought the USB drive version. I plugged in the USB drive first then plugged in the cable. It did nothing. I went into COM ports and saw it there as COM 4. I have not put any effort into it as it was headed to the body shop for...

    Have you checked your ground?

    Sometime for test purposes I advise to add a ground and if the problem is resolved you know what to do. Find that hidden ground and fix it.

    AC Condenser - Should I use New Or Original.

    If you need to replace parts because they are worn, leaking or in rough shape than I agree, replace with modern design. If you need to replace hoses, of course use barrier hose. I think that is all you can find anyway, now. My point was if you were happy with the system using R12 and you are...

    Have you checked your ground?

    I am a field Service Engineer for a major auto manufacturer. I see so many times where a tech has replaced all kinds of parts. I get there and in 15 minutes we have found the wiring issue. Voltage drop testing. Start with the basics, fuses, grounds, etc.

    AC Condenser - Should I use New Or Original.

    I have converted hundreds of old R12 systems to R134a. I worked as an auto tech back when they phased out R12. Converting was simple. Evacuate the R12, remove the compressor, drain out any oil and measure. If you can, replace the orifice tube calibrated for R134a but the R12 one will work...

    Rear Window size question

    Have you tried calling a glass shop? LMC has listings for glass. GM made millions of these trucks. Should be a no brainer to find glass. Local glass company will be best because when you pick it up you can check the fit right there. If there is an issue they can see it. I doubt you will have a...

    1987 454 TBI stalls at idle after a short time

    My Laptop is running Windows 10 and keeps trying to get my to go to Win 11. I am not saying the cable is no good. I only tried for a few minutes and when it didn't work I put it away. My truck was headed to the body shop that day and I just needed to check/set the TPS voltage. When it comes...

    1987 454 TBI stalls at idle after a short time

    I bought the allocable.com usb cable. I could not get it to work. When my truck comes back from the rest shop I need to use it. It is a Windows issue and I have not been able to get the software to see it even though windows sees it.

    First real drive! Not tragic but not good. I think I need carb advice.

    Vacuum modulators are cheap, just replace it and make sure you have good vacuum supply to it. You will have to adjust it to get the shift point where you need them. As far as HEI goes just buy a stock distributor with HEI for a small block. Replace the pickup inside, vacuum advance and coil...
