No. 3 cylinder spark plug removal on 96 chevy blazer
For anybody that's having difficulty removing the spark plug from the #3 cylinder of a 4.3L vortec engine because the steering column is blocking it I have the answer to this problem.
The problem is that you can get the 5/8 inch socket on the plug but cant get a socket wrench attached to turn it because the steering column is in the way.
Use a 3/4 inch ratcheting crescent wrench (5" long) and a 5/8" spark plug socket (2 3/8" long) with a hexagonal head.
Push up the rubber steering column boot up and temporarily secure it out of the way with a plastic slip tie around the boot and the steering column. Put the socket on the plug by passing it under the steering coumn.
Put the ratcheting end of the 5 inch open faced cresent wrench on the hexagonal end of the 5/8 inch socket plug. It fits perfectly in the heat shield surrounding the plug and doesn't present any clearance issues with the steering column allowing removal in under 3 minutes.
