Okay, so I have traced my coolant leak to the dreaded lower intake manifold.

I have decided to take on this issue myself, rather than to pay someone labor.

Can anyone recommend some good step-by-step videos or articles on how to do this? I do not have a full shop manual, but I do have both a haynes and chilton manual.

Note: Although I am a new Blazer owner, and have been somewhat out of the game for some time at doing my own work, I have in the past done lots of work on my vehicles.

You can go to Alldata.com and get a subscription for your truck. It gives you the technical service manual for your truck the shops and dealers use.

I am in the middle of this repair, my lower intake is on the workbench for cleaning.

 

Thanks, Stovey

I will check them out. I just had an offer today from a friend at work who has experience working on Vortecs. I may take him up on it, it will save me a few hours of work, and hundreds if I paid for the labor.
