Evening all, Has anyone had experience with replacing the original GM ac compressor with a Sanden that Jim K sells. My big question does it seem to
have less of a drag on the motor, I know when the original turns on it about 2 hundred rpm at idle I don't believe mine has much left in it by the
noises. Also can it handle an add on air and the factory dash air at the same time like the original can?
Thanks,

Skip Hartline

Skip,
I have the Sanden from Jim K. It works great. It "seems" to be more efficient than the old compressor, but I don't have any hard data. What I like is
that you can take off the valve covers on a 455 with this compressor.

I have it too. It runs the dash air and an aux AC unit I have under the couch just fine. The only catch is make sure your hoses keep clear of the bolts around the pully or the hose will get eaten!

The Sanden is about 1/2 of a GM compressor. The GM easily would cool a 2
bedroom house. But, on early GMC coaches, if you add up the poor design of
the air system to the huge heat loss of the GMC, you don't feel very cool
in hot, humid areas of the country. If the only thing you do is change to a
Sanden, you are not likely to see an improvement, without some other
modifications.

So on a later CCOT system the A6 should cycle off more than the Sanden, saving fuel. Unless the Sanden is less load.

My argument for the Sanden is reliability . Our come back of rebuilt
origional was costing us lot of freight both way as we cover the warranty
that way .
No other dealers do this.
Rebuilders confessed that lack of New parts is why they were failing.
Sanden is a proven unit to Japanese cars and pick up.
Our techs like the kit as they do not need to warranty once it goes out the
door.
You need to clean out the system or the debris will damage the new
compressor

We have sold almost 100 Sanden so when we say anything about our
experience, I know what we're saying.

Like Jim says, you need to have someone who knows what they are doing to
pull down and evacuate the system. The receiver/dehyrator should also be
replaced if the system has been open to the atmosphere unabated.

The Sanden is fewer BTU’s to start with, so it has to be less load.

But in either case, you’re bound by the evaporator, which is smaller than the condenser or compressor.

Skip,

Long before JimK started selling Sanden compressors, I got a Sanden clone
off of eBay for a very low price. It even came with a 10-grove serpentine
belt pulley, which made installation with my already-installed belt almost
trivially simple. Enlarging the 4 holes in the flat forward mount of the
A-6 enabled me to mount the 4-eared "Sanden" there. A simple brace at the
rear of the compressor resulted in a VERY stable mounting. An A/C shop
replaced the hose ends quite cheaply. I've never had a leak (in probably
10 years now), and the HVAC works better than it ever did with the A6. I
heartily recommend the "Sanden". For anyone who needs/wants them, however,
I noticed today that I have 4 A6's to take to GMCMI Tallahassee. :-)
