    R4 Compressor Help

    Four seasons says to add the oil to the compressor then stand it on end for 1-3 minutes to lubricate the front seal. I would doubt the shop is doing that. Also if your compressor had a mechanical failure debris may be floating around the system and taking out the new compressor. You should...

    Have a great Snap On dealer finally

    I had a composite dead blow hammer I bought in the 90s but hardly used. I grabbed it last winter and it shattered. I gave it to a friend who still works in the shop. The Snap-on man replaced it. He also replaced some broken picks and screwdrivers. When I bought my backhoe I needed some 3/4"...

    Are these dual shocks factory. Pic inside. 1987 K10 long bed truck

    Monroe/NAPA has different shocks for quad suspension. I bought my shocks at NAPA for my '87 V3500. They seemed so wimpy and they did not fit right. Went back to NAPA and the counterman said "You have quad shocks, right?". "No, I don't". Got the correct shocks and they were much beefier and fit...

    Have a great Snap On dealer finally

    Unconditional warranty means just that, no conditions. It broke, replace it. Craftsman used to be good years ago about replacement of broken stuff. When my Dad passed a few years ago and we clean out his workshops I find a dozen or so broken Craftsman screwdrivers. Took them to Lowe's and they...

    Have a great Snap On dealer finally

    You buy a franchise you have to honor the warranty. The warranty is not paid for by the franchisee. The franchisee has to do the paperwork and they don't like that. I have called Snap-on corporate a few times when I had my business to get them to honor warranty and stop occasionally as we needed...

    Wobbly power steering pump pulley

    That is the problem with rentals. My puller is a Snap-on I bought in the 80s when I worked on Fords. It does Ford and GM pulleys. Hit up eBay and find a good one there. OTC, Mac, Marco, Snap-on, Cornwell are all good names.

    Have a great Snap On dealer finally

    I see techs with $30-40,000 tool boxes. There is almost no tools in them. They are paying 22% and higher interest rates. Absolutely silly. the majority of my Snap-on tool were bought used. 40 years later I still have them. The dealers use to hate me because I would not buy tool boxes. They also...

    Have a great Snap On dealer finally

    Snap-On hand tools are great. Their air tools, electric tools, and other things are not so great. Snap-On sockets have a thinner wall than other brands. 99% of the time that doesn't matter but when it does....... @Ricko1966 I used to tell new guys starting out. Go to Sears and buy everything...

    Brake Fluid Flush GMT800

    I am with @Ricko1966 on this. I have never seen a swelling brake hose in my 40 years in the service business. Plenty of internal issue causing a blockage and brakes to drag. I have seen brakes that got so hot that the fluid boiled. This made air bubbles in the fluid that had to be bled out...

    Brake Fluid Flush GMT800

    suck the master and refill that with clean fluid then just bleed old school. You should do this at minimum every two years. Brake fluid is hygroscopic. Beside the obvious damage water does it significantly lowers the boiling point of the brake fluid. So when you need your brakes the most the...

    Alternator amps

    As Rick says if you know the right combo you can get what you want. The issue with parts stores now-a-days is they rely solely on the computer. So when you come at them with something not stock their heads explode. If you have an old school store around they typically can deal with requests like...

    Have a great Snap On dealer finally

    That is good news. Tool dealers are hit or miss. All my hand tools are Snap On. After 6 or 8 years I stopped needing to buy stuff and occasionally needed something. The Snap On dealers would stop showing up and then give me crap about replacing a broken tool. I used to have to do what you did...

    Alternator amps

    My '87 GMC has the same alternator. The model is a 12Si. They came in a few amp ratings but all were physically the same size. So go with a 94amp unit. I recommend Bosch AL559N. It is new and carries a lifetime warranty. You will have to swap the pulley. CS130 alternators are great but they are...

    Wobbly power steering pump pulley

    You will also need an installer to put the pulley back on. They are also cheap.I could not find my installer. I have/had a Snap-On one I bought in the 80s and haven't needed it in 25 years so god only knows what happened to it. I just picked up a brand new unit off eBay. Military surplus brand...

    Practice welding a lot before you try welding on your truck. Go buy some 19 ga metal and get good at welding it. Vertical, upside down and on the flat. It take a ton of practice. If you are welding outside consider using flux core. Yes, you will have to chip slag but a little breeze won't mess...

    Do I restore my AC or?

    I thought G bodies were 1982-1987 and A bodies were 1978-1981? Not that it matters. I may be wrong. I was a Ford/Volvo tech in the mid80s.

    Dual Battery

    Is the effort worth it? Just make sure your alternator is big enough and the alternator and battery cables can handle the loads.

    Do I restore my AC or?

    My 1981 Pontiac Grand Prix had an R4 compressor. GM was using them at that time, at least in the A bodies.

    Do I restore my AC or?

    That would be an expensive and time consuming proposition. I might consider this if I were building a daily driver but I am building an occasional use truck. My 1987 GMC is at the body shop and that A/C hasn't worked in a long time. The truck was not really used much for the last 20 years. Now...

    Cracked TH350 case

    TH350s are pretty common. Why screw around with trying to get it fixed? Just buy a rebuilt unit or a used one that needs a rebuild and use the case. I saw Edelbrock's post about $50. I doubt in my area I could find anyone to weld that for under $250. Then you have to make sure the seal surface...

    Dual Battery

    You can wire them in parallel. Hook the two positives together and the two negatives together. You could also use a battery isolator to keep them separated nd prevent a dead battery from draining the other one.

    Body repair panels

    My NOS rocker and door needed the same amount of massaging that the repro rocker for the other side needed. These are mass produce vehicles and not precision built. The bodyman said to me, "I probably shouldn't have had you buy this NOS door. You should have bought a used one. It probably...
