Trailblazer 4.2 Engine R&R
The Trailblazer 4.2 is not an easy engine to pull. Besides just being tightly packed into the engine compartment, it also has the front axle shaft running thru the oil pan. This is NOT a step-by-step procedure of how to pull the engine. Rather it is a guide to what you can expect to run into if you do have to replace an engine. We hope it helps.
