Kit contents:


Early V8 and Diesel Engine Rotation Socket and Extension

27mm / 1 1/16" six point 3 in deep socket with short extension just the right length to fit into the front pulleys and clear the radiator on most early 6 clyinder, small V8 and diesel engines from the early 1960's up to 1985

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.

There are no quick levers to pull like on other models, but with the right tools and know how you can get the hood straight up quickly.

Use it to extract OR fill transmission, engine, power steering, brake reservoir, SLS tank and rear end fluid
