    Searching for an AC switch

    I hadn't noticed that time gap from the original post... I was hurrying before work to look up a switch that was fairly universal thinking someone was needing a quick answer ;)

    Searching for an AC switch

    Here is a very universal one that even GM used for a few years on factory systems.

    Searching for an AC switch

    That is the thermostatic cycling switch, with the fan resistor pictured above it. It has a capillary tube that goes around a cold pipe of the evaporator and it wrapped with 'dum dum' aka prestite tape. Can you estimate how long the capillary tube is, and is the switch a fixed value (it may have...

    What is this sensor?

    If you look carefully at the corresponding connector on the wiring harness, many GMs could plug into both the button style connector (like shown) by plugging on to the sensor perpendicular (with the little half circle cut out in the connector), or plugging straight on to a spade style connector...

    gm big block v6?

    The back half is at the yard on Garrity. An entire '64 Corvair is on an elevated stand in front of the State St. location.

    gm big block v6?

    Here is the V12 that has been on display in front of one of my favorite U-Pull-Its for decades.

    Long Time Lurker

    Thanks goodness for that! What carburetor is on your Offenhauser intake manifold? You are right about a 292. You can conceivably make a 292 out of the shorter deck block, but I understand the connecting rod angles are not good, unlike with the taller block. Here is my 292. You can see the fuel...

    Anyone ever seen or messed with a GM 4L30E?

    Most immediate failures are far better that getting 'the phone call', after the catastrophic damage has occurred to the wife, daughter, son, etc.

    GM made a mechanical asshole version of the 4T65E for Volvo too. https://tripleedgeperformance.com/Volvo-Transmissions.html

    '89 Celebrity Wagon

    GM assembly plants have a long history of torch work. When Corvairs had factory A/C ('65-'67), the 3 holes for the vents in the metal dash (and elsehwere) were cut out with a torch! Same for the openings for front door speakers with stereo ('65 -'69). Isuzu Diesel powered Chevettes ('81-'86...

    small block buick - carburetors, radiators, suggestions?

    The 'hot air' comes from the exhaust crossover port inside the intake manifold. The heat from the exhaust warms the choke mechanism / tube, just like the electric heater does on the electric version. Oldsmobile used it clear to the end of production on their V8 Quadrajets in the 1990 model year.

    Turbo 400 filter(s)

    That's good to know. I've only ever used a single O-ring from the kits, but only had one that seemed to be a problem, oddly the only cheap filter I purchased.

    Turbo 400 filter(s)

    Had an AutoZone filter do that on my T400 too. Had used NAPA fabric filters in the past with no problem. Most recent have been AC Delco. I understand as well they very sensitive to flow.

    Wiper Pulse Module #15598496

    I thank you so much for posting this! It hasn't been a priority for me to fix mine, I at least have the 'mist' position for a single pass (since I added intermittent wipers), and I live in the desert. I hadn't opened one of the modules yet (I am an electronics nerd by trade, for anyone that...

    I am a V6 soccer mom now! Lol

    At least you have them, just in case.

    I am a V6 soccer mom now! Lol

    Unless you are having an issue, or bought genuine OEM, I would not change out the coils. Parts quality is deplorable, IMHO.

    Removing Smog on a 81 305

    Adding convertor (s). Yes, I said adding.

    While none of them like a rich mixture, the 3 way catalyst (containing platinum, palladium, and rhodium) for control of HC / CO / NOx is dependent on a feedback fuel system (O2 sensor) for most efficient operation. The older design (2 way) for only HC and CO, not so much. Did you know it is...

    Cassette Tuner Recommendations

    IIRC, in the MON position, you can have music and it will be interrupted by transmissions, dependent on squelch setting.

    Looking for the elusive disposable Th200 Non Lock-Up

    What I think that I am hearing is that my original, early 700R4 (built '83) behind my LG4 in my '84 Caprice with 275K miles is worth A LOT to the right person :laughing1:

    Looking for the elusive disposable Th200 Non Lock-Up

    The THM 200C was the base automatic transmission with the new 4.3L V6 for '85. I'm not sure that the 200R4 was ever offered with the 4.3 in the G-body.

    Looking for the elusive disposable Th200 Non Lock-Up

    Would it be provocative to say the THM 200 made its debut in the 1976 Chevette and Vega, for which it was designed? Then someone at GM said for the 1977 model year, "hey, lets put as many of these as we can in nearly every car line. It will generally last as long as the warranty". Still looking...

    power window motor question

    IIRC, you can insert an object in the hole and press the 2 dissimilar layers of metal together (thermal overload protection, cheap, crap design) when they have opened abnormally. This is supposed to allow you to operate the motor (if obstructed in some applications) to access it for repair.

    Straight 6 to V8 swap?

    Since it is probably an integral head 250, keep an eye out for a non-integral head and intake manifold, if you want to keep it. I've long suspected the integral head offers better performance compared to a stock, non integral, but the cracking issue is overwhelming. You'd need the matching...

    Power Steering Gear Leak

    I drilled a tiny hole in the metal of the lip seal, and threaded a screw into it. I was able to pull it our easily. Lots of fluid leaking out, so cleanup of any shavings was easy.
