AC in our trucks with a SBC - which side for the compressor? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Woogeroo · 07-10-2011, 08:10 PM

Howdy.

I'm just curious... for those of you that have or had added Air Conditioning to your trucks.... looking at the engine from the front of the truck... which side do you have the ac compressor on?

The reason I ask is my alternator is on the left.

Anyway, just curious....

Left side looking at engine.
(which actually is the right side)

**Clyde65** · 07-10-2011, 08:42 PM

most aftermarket ac folks has it set up on passenger side.

Clyde65, yeah, I've noticed that on a few installs or the instructions for the various setups.

This is how my truck was when I bought it, always thought it was a little funky.

When I added A/C I purchased a set of Alan Grove brackets and moved the alternator to the driver side allowing the compressor to mount on the passenger side. Mounting it on the driver side is going to require some inconveniently long hoses.

**Captainfab** · 07-11-2011, 01:50 AM

The original location for the A/C in the '72 and older trucks is on the passenger side with the alternator on the drivers side. Of course this is with the short water pump. In '73 when GM went to the long water pump in the trucks, the alternator went to the passenger side and the A/C on the drivers side

LT1 Burb · 07-11-2011, 10:03 AM

Mine is on the driver side.

**Clyde65** · 07-11-2011, 10:09 AM

maybe a serp belt system is in your future?

66 lwb cs · 07-11-2011, 11:28 AM

Mine is on passenger and it is a 60's era aftermarket unit installed in 1966

awbrown · 07-11-2011, 02:51 PM

looks like a newer pump on that 66 setup...

kieth · 07-11-2011, 04:32 PM

I have a 91 burb serpentine belt system and it is on the passenger side, I thought when I measured my water pump it was a long shaft but maybe I misunderstood how to measure it. Kieth

R4 compressor in place now pass side, will soon be a sanborne......

New pump and condenser the old one's went bad so the new ones run R134

karlbenz · 05-04-2023, 08:30 PM

My serpentine setup came out of a 96. Compressor on drivers side

Arne · 05-04-2023, 08:59 PM

My '64 has an early 80s SBC with passenger-side alternator, and a custom new wiring harness for that application. So the A/C compressor will be on the driver's side.

SCOTI · 05-05-2023, 12:04 PM

Woooowee..... Dusted this one off.

forestb · 05-09-2023, 08:10 PM

The first photo is of my old engine and the second is of my new engine. I had to get different brackets because my new engine has Vortech heads and a vortech intake manifold. Both are from Allen Grove.

Here are a couple of adapter pipes I'm using to clean up and shorten the hose runs with my driver's side compressor. I got these from Auto A/C Solutions, but both are available from Old Air as well.

This first one allows the large suction hose to run along the firewall, behind the carb. Still a medium-long hose, but much nicer routing than over the top.

This extension pipe for the condenser inlet crosses over to the driver's side. It allows the hose from the discharge of the compressor to drop down and connect through the left side of the radiator support. This is a much shorter hose than having to run over the top and into the condenser on the right side.

And here is the completed install. The extra pipe adapters allowed me to simplify and tidy the hose routing significantly. It turned out nicer than most left-side compressor installs that I've seen.

Not a problem to reply to an old thread if the reply has related information and provides meaningful input to the overall message board.

x2. I like that people are utilizing the search function & finding relative information. It shows the value in these forums.
That being said, I'm amazed sometimes @ the time gap on some. Twelve years is a pretty decent stretch.
