The Stovebolt Site Forums The Shop Area Engine Shop Air conditioning on a 6 cyl.?

I want to put air in a 1937 with a 1970-250 6cyl.Does anyone make a "stock" compresor mounting brk.?And maybe a 3 groove water pump pully?I have the power steering pump and alt. on the driver side already, so it has to go on the pass. side I know. Thanks for any help you can give me!

I put an A-6 on mine, made my own brackets, wasn't that hard. Or you could junkyard a setup from a Nova, truck or............
Not too hard to find

I think Johnnny has the right idea;find a Nova with A/C in a wrecking yard,and get everything you can that relates to your project. That way,you have a reserve of related parts to draw from if needed,and once the A/C is installed and working you can dispose of the parts you didn't need. If the factory bracket doesn't tuck close enough to the engine or something like that,it's often easier to modify an existing bracket than to build one from scratch. Or keep 'em,in case you think of something else you can make out of them.

I would run away from a stock compressor of the vintage you have as they are R-12 take alot more power to run.

Sanden type modern compressors are R-134(cheap!) and aftermarket brackets for your six are much better looking!

Take a look at www.alangrovecomponets.com or www.vintageair.com

They are only r-12 if you put r-12 back in them. If the compressor is off the car, you can remove the oil and go with 134a OR leave the oil in and use Freeze-12. There are also numerous other refrigerants out there including one called Envirosafe. Here's one that I found very interesting:

Some compressors don't like conversions. I would just buy a new one and use 134a. I wouldn't use anything not approved for use in automotive systems like freeze12 and others. Freeze12 is just 80% r123a anyways. Buy the right stuff and at least it can be recovered at a shop later if you have to fix the system. In california at least we have to identify refrigents now before working on the system, if you had freeze12 in it you would get turned away or charged a ton of money for disposal. The newer sanden type compressors are scroll type and are more efficent.

I want to run a homemade kit on my 56 3200 but can't figure out the bracket part. also the belt groove on my harmonic bal. is only setup for one belt, would I need a longer belt or another harmonic bal. for two belts? also where would the compressor go, etc... I figured I'd buy the under dash kit from vintage air or get a vintage air off ebay. I heard you can't get brackets from them....

Patrick's has a set of brackets that puts the a/c compressor where the generator used to be and the alternator above the intake on the same side. The compressor has a two groove pulley and is hooked up the crank and water pump with a smaller belt to just the alternator. Set of brackets is about $100, maybe less.

I'd like to add p/s in addition to a/c and am going to drill the old pully off the harmonic balancer, thread the holes and bolt in a two belt pulley to be able to run the p/s on the passanger side of the engine. I think I found a aftermarket bracket that'll work but am going to try looking at the brackets on other l-6's in the boneyard and maybe have my block/head drilled and threaded to use one of those, if there is meat in the right places that could be drilled/threaded.
