    Comments about Dorman - Help Air Conditioning Bypass Pulley:

    After reading the other reviews for this product I got a package of 3/8 washers to use as spacers for the install. But upon install with 3 washers as suggested since i wanted to install 1 time and be done I found they were not needed on my make/model. now other cars may need them but the 1992 buick century i drive did not need any to line it up perfect with the other pulleys. I did require the removal of the old a/c pump which had 3 bolts 2 where this goes and 1 on drivers side of pump where the hoses attach to it. but this pulley only needs 2 bolts and it seems plenty solid. Much better than replaceing the a/c on a 20+ yr old car.

    Word of advice though... do invest in a set of the low clearance sockets to get the old compressor off. and if you use about a 20" 3/8" extension with a 15 mm socket you can get the top bolt no problem by going BEHIND the exhaust manifold. just be sure to actually unhook the battery before starting since you are blindly feeding a metal rod behind the exhaust manifold right above the starter.

          Compressor had to be removed, 2 holes were only needed no third hole available on bracket. Had to be shimmed out with washers about 3/16 of an inch. I measured the old pulley from the fender and put the new one on and shimmed out with washers. It works perfect. good deal for a small price

              Comments about Dorman - Help Air Conditioning Bypass Pulley:

              When this pulley is installed properly it should work just fine. It is meant to replace the A/C clutch so the compressor should stay on the car and just the clutch removed. Then all three mounting points will line up. If you do remove the entire compressor then you can use two mounting points and a few washers to space the pulley out and line up with the other pullies.

              I choose to pull out the entire compressor and install the pulley in its place. Without washers the pulley doesnt line up and will squeak and cause the belt problems others have mentioned. But once the washers are installed the squeaking went away and the belt was centered on all pullies.

                check the alignment with your other pulleys, when i used it it jumped off because it does not align properly, so easy fix was to add 3 spacer washers to equal about 3/8 of an inch between bracket and bloke,been 2 years and still working fine.

                          this product is very poorly engineered, dose not fit properly , there are three mounting holes and only two line up , there is no place to install a third bolt !! ,Pully will rattle and eventually break and belt is not lined up properly, had one on my van and it broke ,put another one on and it eventually threw the belt and belt tangled aroung crankshaft pully and caused 800.00 worth or damage , would never buy this product again and would never recoment it to anyone , STAY AWAY FROM IT !!!

                              If you use this, you will have to remove the compressor from off the vehicle and use this in its place. If you use this, the same size belt is used as if the compressor was still being used.
