Hello and thank you for using JustAnswer. My name is XXXXX XXXXX I will do my best to help you with your Chevy problem.

Replacement of the manifold gasket is pretty straightforward, should take about 2.5-3 hours.

Do you think someone who has never done this before should be able to follow your directions and be successful at this?I would probably number everything I take apart so I can mate everything back together(1to1,2 to 2 etc.)Do you have to tork(no sure how to spell)manifold nuts down in order or just tighten them in order?



Expert:  Dave Nova replied 5 years ago.
I do thing that someone with some mechanical experience can tackle this job. Take some pictures with your cell phone or camera of the electrical connectors and vacuum lines as you go. It will be a big help in getting it back together correctly.

The manifold nuts should be torqued to 25 Nm (18 ft. lbs.) in the sequence shown below during reassembly.

So taking the nuts off one way and putting them on another? I just checked,the part goes for $11.00.Then new anti-freeze and new oil and filter. Probably less than $50.00 to do the job if I don't screw up.So on a scale of 1-10 (I have mechanical experience ) what do you think your confidence level would be?


Expert:  Dave Nova replied 5 years ago.
Yes, take the nuts off one pattern, then installation is the reverse. This helps to keep the manifold from warping. I am fairly confident that you can do this job. I would give you a 7 or 8 on a scale of 10.
