1969 EL CAMINO 350 DOUBLE GROOVE WATER PUMP PULLEY UPGRADE
This water pump pulley is a must-have for anyone looking to upgrade their 1969 Camaro, Chevelle, El Camino, or Nova. Faithful reproduction includes correct part number stamping and coding as original. Also, some of the later style aluminum water pumps with a serpentine-belt drive system used a reverse rotation pump.Water Pump Pulley - 396/375HP Deep Single Groove - 1969 Camaro Chevelle El Caminoġ969 396/375HP Deep single groove pulley. For a long pump these measurements come out to 7-inches for the small block long pump and 7-1/4-inch (7.250-inch) for the big block long water pump. Again, though, the best way to confirm is by measuring from the gasket surface to the water pump pulley hub surface. Like the short pump visual clues, if the alternator is mounted to the passenger side of the engine it is most likely a long water pump application. The gap is approximately two finger’s widths wide and most people can slip a good portion of their hand between the engine and the water pump as a simple test. Similar to the short water pump, you can usually spot a long water pump installed on an engine by the extra-large gap between the back side of the pump and the engine’s timing chain cover. The long water pump appears similar in design to the short water pump, however, it has longer cast “legs” that move the main body of the pump away from the engine. Starting in 1969 GM moved to the long water pump for cars and 1973 for light trucks. The big block pump’s mounting spacing is different as well, but obviously that can be difficult to determine with the pump off the engine, so always confirm the “height” of the pump is correct for your needs. Big block “short” pumps measure in at 5-3/4-inch (5.750-inch). The Corvette used its own version of a short water pump from 1971-1982 due to engine compartment clearance issues with a special 5.795-inch height, so be aware of those as well. Small block “short” pumps measure 5-5/8-inch (5.625-inch). Use a straight edge or a ruler placed across the pulley hub face. Place the pump on a flat surface with the shaft pointing up. If the water pump is unmounted, you can take a measurement from the pump’s gasket surface to the pulley’s mounting hub surface to confirm that it is indeed a short water pump. Short water pump applications placed the alternator on the driver’s side of the engine. Another quick visual check if the engine is complete with all accessories is where they are mounted. While this is not definitive, it is often used as a quick “junk yard” test. The water pump is usually easy to spot when installed, as the relationship between the water pump back plate and the engine’s timing cover does not allow your hand any room between the two.
GM used the short water pump on car applications up through the 1968 model year (and 1972 for light trucks) except for the Corvette, which used the standard short pump through 1970.
