Full size GM 'B-Bodies' did that from at least '77-90.

I love the unique features of the '68. My folks bought a '68 427/390 coupe new. Yellow, manual steering and brakes, but it did have the AM/FM too!

Beautiful! Which 427? I'll guess 390 horsepower?

Same setup still on the 2019 Yukon Denali. I am currently adding a hot lead at the unused position. I really don't like the setup near the engine heat, when there is still room (and even what looks like the battery base stamping) at the front left corner. If the intake air/filter box was...

Yep, one of the 3 diodes is shorted from the stator is shorted (if remember the schematic correctly). Exactly what mine did. I took a look at it and was not impressed, throw away junk IMO. I used to repair the 10SI/12SI units.

I've had a rectifier diode short inside the original CS130 series alternator (1996 car). It was red hot and squeeling, no indicator light issue. They are not particularly good series of alternators.

Unfortunately, all Corvair cars came with 13" wheels. The Corvair trucks all came with 14" wheels. No styled wheels for either.

That is a 1965, the first year of the 'late' design ('65-'69). Only coupes and convertibles were sold in '68-'69. Had the car survived, GM was faced with changing the engine. Being air cooled was a nightmare for emissions. They had already dropped factory A/C for the last 2 model years because...

That's good. They claim that failure was fixed for your 2018 (I have a 2019), but I'm a little skeptical.

A static pressure reading does not indicate charge quantity. Look at the driver's side top of the condenser and see if it happens to be oily.

Exhaust passage through the head, apparently. I've never had a Duke/Tech VI. A coat hanger and a vacuum if the ports are blocked. I've only seen them clog on the intake side myself.

Negative backpressure, ruptured diaphragm as you already diagnosed. I believe some of the aftermarket replacements are serviced by non-backpressure units.

Not if it is a positive back pressure EGR valve. GM began using positive and negative back pressure EGR valves back when still using carburetors to control EGR flow. Does it have an N or P at the beginning or end of the part number on the top side of the valve?

I've done 70s-90s GMs (A6s-R4s) with the newer, double lip seal. I don't necessarily recommend it either, but I wasn't about to scrap a good, quiet R4 over leakage. Even new ones are a crap shoot, since it was a mediocre design to start with.

I believe they are 2014 to 2020. I have a 2019 Yukon Denali (not XL) and love it (6.2L 10 speed). Others have far more transmission knowledge and experience than I will ever have, but I believe the 8 speed is to be avoided. There is an A/C condenser issue (refrigerant loss, oily spot, top right...

I've got a 2019 Yukon Denali (17K miles) and a 2020 Kia Forte (32K miles), besides my 1978-1996 fleet. The GM oil life monitor has amazed me!

Now that I looked up the ION to see what it used, it looks like a GM V5 compressor. It is leaking a the main body o-ring?

I can feel your pain. Even the owners manual said to take it to the dealer for bulb replacement on the sedans (Wagons were easy). These have a bulb count of 15 (17 with the high mounted stop light), a lot of 194s. Quite an assembly when it is out.

Back at it again, though I am sure getting slower. Now at almost 259K miles.The front valve cover was leaking and marking up my driveway, and it had a leaking thermostat gasket. Decided to do it all at once. Wouldn't have needed to remove the alternator, if I hadn't broken both my 15mm flex...

I expected to hate the Ford designed 10 speed in my 2019 6.2L Yukon Denali, but have been thoroughly impressed with it (so far). It certainly shifts quickly and smoothly, especially compared to my E4OD, 4L60 or 4T60E.
