York to Sanden Conversion, Doug AC Fun Options

[Mblizzard]

Ok so I told myself the next time I pulled my engine I was going to get rid of the York compressor that seems to barely work. The system is currently R134 somehow but I am not sure that the Sanden 508 is the compressor I should go with. It seems like the 505 or 507 would be sufficient.

Anyone have a line on where to get a 505 or 507? 508s are easy to find but I though going down a size would ease installation.

Thoughts?

I purchased both the fixed and adjustable York to Sanden brackets. Initially I thought I would use the adjustable but switched plans. The adjustable requires spacers which I had to buy separate. Even on the bench I was not thrilled with the fit and finish but when I test fitted in the car I realized the bracket simply takes up too much extra space so went to the fixed which proved simpler but better.

1. The Seltec compressor I used is model 103-55021. It fits neatly but snugly. Might have been easier with next size down. So many fake (Chinese) Sanden's out there that I felt better with the seltec and it works flawlessly. Note that the compressor pulley sits higher than the York. Thus, the tensioner idler pulley really winds up doing nothing (although I did pop a new bearing in there).

2. For me, the proper belt turned out to be a Gates 7460. As noted, you do not get a lot of room to adjust belt tension. Make sure you have the pulley behind the fan lined up right or you will need to do it over again (as I learned).


3. I replaced hose and fittings with Aeroquip EZ-Clip components. The hose is more flexible than barrier hose and the clip system is easier than crimping. Size 8 hose on the high pressure side, size 10 for low side, a small piece of #6 from condensor to receiver drier.

5. I stuck with R12. Y need to drain approx 4 oz of oil from compressor and replace with mineral oil (available at Napa). If you flush out the evaporator and condenser, add an ounce per component.

Definitely easier with engine out although not too bad with engine in.
