    Has Anyone Bought This A/C Compressor?

    GM / Delphi sold off the rights many years ago (last model year of use is now 23 years ago), so they are 'aftermarket', no matter what label is on them. There have always been rumors about different grades of them afterwards, but it is hard to say. All I can think of (being the R4), is 'the...

    Is This (Crappy) Connector Necessary?

    I believe it is to make the harness 'modular' i.e. where the engine mates together with the body. Mine had gotten hot enough before replacing with crimp connectors (soldered and with heat shrink, slid inside the original plastic connector) that the 10 gauge wire was contacting the compressor...

    Radio not working after sitting in garage?

    Move the AM/FM lever back and forth and see if it comes to life.

    R4 to Sanden whith stock ac lines(for serpantine)

    That's a great conversion, there wasn't a GM compressor more poorly suited to a dual air Suburban than an R4, especially with R134a. I'd considered a GM V5 compressor, but the reversal of the suction and discharge ports was a problem. Do you have the compressor mounted inverted with the...

    Any one seen gauges with this??

    What year was this from? Anything in the overlay for the other two positions?

    250 I6 with Offenhauser 3x2s!

    After years of delay, I'm finally starting my TBI project for my 292 L6. The stumbling block for me was always $300+ for a manifold. Finally found a deal on a nice, used one.

    Is my AC compressor sized up?

    If turning it on nearly stalls the engine, and all is good when turning it off, it is internal to the compressor. The pulley bearing would be an issue any time the engine is turning.

    Need opinions: DIY TBI Tuning

    I'm following this one with great enthusiasm. I finally got an Edelbrock intake manifold for my 292. I plan to run a '427' ECM with 2.8 / 3.1L TBI using 305 injectors. I'm no novice at electronics and computers, but I know I will have a lot to learn with tuning.

    1982 250 4.1l inline six stalls when coming to a stop

    Funny some of combos that could be put together back then. I'm not sure when PB became standard in 3/4 and 1 Tons, but they were an option in a 2WD 1/2 ton at least through '85.

    1982 250 4.1l inline six stalls when coming to a stop

    The OP says it is a 1 barrel, but 250s in '82 were integral heads w/ progressive 2 barrels, so it may have been changed around with unknown parts. If it is still the 2 barrel, they were known for thottle shaft wear issues causing idle issues.

    1982 250 4.1l inline six stalls when coming to a stop

    The goofy Chevy dealer in Daytona Beach was still selling base trucks in '85 with PS, auto, A/C, radio and manual brakes!

    Ball Joint Advice

    The lower ball joints carry the load in that design, so they do wear faster than the uppers. If you lift at the lower A-arm, you can tell a lot more than when is at full travel, as when lifted only at the frame of the car. I could hear mine years ago. I was shocked at how loose and rough the...

    Any good hacks/upgrades you've come up with for our trucks

    GM has a habit of recycling designs through out car lines, all 4 terminal seat belt buzzers / chimes have the same pin out (through '84). I have a B-body seat belt chime plugged in where the original seat belt buzzer was. There are 3 extra leads off the module, one hooked to the dash lights at...

    Flasher relay

    Steering column contact issues in the N cars, IIRC.

    ‘89 Caprice Mini Thread

    I had studied the shop manual a lot too, with a meter taking measurements on the board and contacts. There is a contact that sticks out the back of the pulse board that didn't seem to be addressed by the FSM either. The pulse board is actually quite simple and only has about 50 cents worth of...

    ‘89 Caprice Mini Thread

    Most likely, it is the pulse board. I'm quite good at a lot of things for a layman, IMHO, but the hidden wiper system is a confusing electro-mechanical bag of worms. I finally gave up and bought a complete, remanufactured unit from O'Reilly's. I don't normally do that kind of thing, but the...

    Sorry, I wasn't trying to be weird. It seems a lot of posts appeared in between while I was trying to respond about the Stakeout movie.

    ‘89 Caprice Mini Thread

    I saw that in the theater when it was new! Still love that movie. Drove my Caprice to the theater in Daytona Beach with a friend and his girlfriend. I can't really be as old as I feel, I've still got the same car.

    Rare????

    Oh wow, how cool! Family's business had one new, plain Jane Big 10 work truck with a 350 auto, LB. I learned you didn't pull out an nail the throttle, like I was used to with Corvairs. I can't imagine that one!

    ‘89 Caprice Mini Thread

    I was recalling that the diverter was very different, but I personally hadn't examined exactly how one worked. It's probably unlikely that it can block the air flow completely by design. The situation I saw was a restricted check valve or actually blocked air tubes so it howled when it switched...

    ‘89 Caprice Mini Thread

    I have seen a blocked port cause a strange howl from the pump. I wonder if it may have the diverter valve stuck? I should have mentioned to expect a 200R4 when you said there was a tranny leak. IIRC, all Caprices got the 200R4 from '88-'90 (maybe only '89 - '90) unless it was a 350 (9C1 and...

    ‘89 Caprice Mini Thread

    Sounds like a good plan. I had that in the back of mind as well for my pickup. The unique B-body parts and an intake manifold for the 292 (besides motivation, time and money) have been my hang ups. The truck really needs it more than the car, I just don't drive it as much. Unlike most folks, I...

    ‘89 Caprice Mini Thread

    It's been quite amazing, only opened once 20+ years ago for the rusty looking stuff that used to collect in the bowl. Fuel economy and drivability are excellent, in general. My thoughts now are looking forward before I get into a throttle plate wear issue, but more so the hot weather issue. My...

    Yep, for my '84. I think you are correct about the '91+ until the LT1. The only difference I know of is the fuel tank. I keep dreaming of finding a complete donor.

    My other pride and joy.

    I have pictures here from the rust free, Intermountain west that will bring grown men to tears. I'm 99% sure the Turbo Gran Prix (mentioned early in the thread) was crushed completely intact. The only thing taken from it was the special paperwork / owner's manual that I have. It had been...
