DD-LS-AC-SANDEN - LS Sanden 508 A/C Compressor

All threaded holes in the block and cylinder head should cleaned and tapped with a thread chaser. All bolts being installed should be lubed with a light oil or anti-seize on the bolt threads before assembly.

*We recommend leaving all of the bolts slightly loose until all the parts are installed. Then go back and torque each bolt to 28 ft. lbs. Install the smaller rear bracket using 2 "A" spacers between the bracket and passenger cylinder head using two counter sunk bolts as shown. Leave these bolts loose, do not tighten yet. On some VVT and corvette engines, the water pump must be removed to install the lower bolt.

Corvette accessories do not use an "A" spacer. The rear bracket bolts directly to the head.


Using the longest bolt and a stainless washer, install the larger front bracket using 1 "B" spacer between the two brackets and 1 "A" spacer between the rear bracket and the cylinder head.

Install the remaining two "B" spacers between the front and back bracket using the two countersunk bolts through the front plate and thread into the rear plate.

Now install the Sanden compressor between the two brackets. The compressor should be installed against the front bracket and spacers "D" between the backside of the rear bracket and the compressor, and spacers "C" will be placed between the rear of the front bracket and in front of the front compressor ear. Use stainless washers on both sides.




VVT is different. It only uses the "C" spacers between the backside of the front bracket and the front compressor ears. On VVT the belt runs on the front most rib of the compressor.


While lifting the weight of the compressor, tighten the counter sunk bolts first, rear bracket to cylinder head, then the front bracket, and finally the compressor to 28 ft. lbs. Next install the upper pulley with an aluminum spacer between the machined pulley stand and the front bracket.  The additional stainless washer and nut go on the backside of the pulley bolt to secure this bolt from coming loose.




Place the flat aluminum spacer plate that comes with the tensioner between the tensioner and the front plate as shown. Tighten tensioner bolt to 28 ft. lbs.



To install the belt place a 3/8 ratchet and extension into the front of the tensioner and twist down.



Correct belt tensioning can be determined by the distance between the tensioner and idler pulleys. When using small diameter pulleys and test fitting belts, you want as close to 2" between the two pulleys as possible.
