We bolted the water pump on first, although it can be installed at any time. The pulley bolts are metric, 8x16mm with 1.25 thread pitch. The driver-side alternator/power steering bracket installs with five fasteners. You must install the bare bracket first because there's a mounting bolt hidden behind the power steering pump.We bolted the water pump on first, although it can be installed at any time. The pulley bo Make sure to order the parts for the vehicle you used as the donor car. Remember, the water pump will be reverse-rotation. Here's a tip: You can always tell a reverse-rotation water pump because the pulley will be smooth since it runs off the backside of the belt. All we did for the small-block setup was clean up all the brackets, blast and paint the pulleys, and then bolt the system together. We didn't need an A/C pump and discovered that Dorman makes an A/C-delete pulley that bolts in place of the A/C compressor. This requires the use of the entire A/C bracket, but by doing so it allows you to retain the stock belt length. We also opted for a new idler and tensioner assembly because the bearings in these pulleys are usually nearly dead. The beauty of this system is that whenever you need a replacement component, you can find it at any auto parts store. That's especially nice if you're in a hurry to get the car running. If you purchase everything we list for the small-block Chevy engine swap (excluding the power steering pump $50.00 core charge and shipping costs), the price comes in less than $290.00. This makes it virtually a brand-new accessory drive with new or rebuilt parts. To put that in perspective, the Scoggin-Dickey price for the non-A/C version of the GM Performance Parts accessory drive system is $550.00 or roughly $260.00 more. If you crave a little bling, March sells aluminum pulleys for this system as well. So this is a pretty good deal, and there are plenty of opportunities to shave cost if you're creative. Late-model power steering pumps use a Saginaw fitting (identified by a small O-ring, arrow 1) for the pump's high-pressure side. Older muscle car power steering pumps use an inverted flare fitting (arrow 2). What's cool is you can remove the Saginaw fitting from the back of the newer pump and replace it with the older inverted flare fitting from an older pump-it bolts right in. This way, you may be able to reuse the original high-pressure power steering pump hose. Slick, yes?Late-model power steering pumps use a Saginaw fitting (identified by a small O-ring, arrow The power steering pump pulley must be pressed on. Instead of an expensive install tool, you can get by with a 2-inch-long, hardened 3/8-inch bolt, a nut, and a large, hardened washer. We used a Craftsman strap wrench to hold the pulley while pressing it on. Make sure the pulley is fully seated on the pump shaft.The power steering pump pulley must be pressed on. Instead of an expensive install tool, y The A/C bracket bolts to the engine on the passenger side with two bolts in the head and one in the same bolthole that is drilled and tapped into the fuel pump pushrod hole. Make sure your mounting bolt is short enough. If it is too long, it will bend the fuel pump pushrod. Once the A/C pump bracket is installed, the Dorman A/C-delete pulley replaces the compressor. The A/C bracket also mounts the belt tensioner and idler pulleys.The A/C bracket bolts to the engine on the passenger side with two bolts in the head and o Here's another trick. You can save a little cash by buying a replacement tensioner pulley as opposed to an entire new tensioner assembly. The pulley is attached to the tensioner with lefthand threads. This is because you use a lefthand (loosening) motion on the pulley bolt to release tension and remove the belt.Here's another trick. You can save a little cash by buying a replacement tensioner pulley Here's our finished serpentine system with all-new or rebuilt parts, including new tensioner and idler pulleys and a new Gates serpentine belt. This system is good for a minimum of 70,000 miles (and probably more), and we only spent $287.73, plus shipping. With a used alternator and power steering pump, you could get by for less than $200.00.Here's our finished serpentine system with all-new or rebuilt parts, including new tension « | 1 | 2 | 3 | » | View Full Article By Jeff Smith Enjoyed this Post?
