For a number of maintenance operations, you need to be able to turn the engine over by hand. This includes valve adjustment, timing chain replacement, injection pump timing on diesel engines, checking and setting internal engine timing, draining the torque converter, and others. The best way to do this is to get the front crankshaft end bolt and rotate the engine clockwise (from the front) with a big ratchet wrench (see related products below). The problem is you need just the right length socket and extension. Too short and you can not get on the bolt head and rotate the engine. Too long and your wrench runs into the radiator or radiator fan shroud. Watch the video below as Kent explains the challenge and demonstrates the solution to rotating an engine by hand.
