Hi working on my f150 Intake and have the shop manual but it's very vague. Can someone help with the toque specs for this.. Thanks in advance. i had to destroy 1 bolt then order all new bolts as they seem to be starting to rot. New intake manifold also. Have to drill and tap out one hole.. arrghhhhhh.

 

Install the manifold bolts loosely ,then tighten the intake manifold bolts in the sequence pictured.
Tighten to 89 lb-in.....

 

You mean inch pounds or foot pounds... just sayn. thanks again dude...

 

lb-in = inch pounds

89 foot pounds,, gonna stretch some bolts

 

If that is a plastic manifold, the spec has to be inch pounds. Don't know where this pound inch stuff comes from. 89 foot lbs will destroy a plastic manifold.

I would do it at 40 inch pounds first then take it to 89.

 

Thanks guys, ur the bestest as usual...

 

The abbreviation can be either way, lb-in ‘or’ in-lb.
Either way the meaning is one 12th of a foot pound...

 

I got it going and runs great too, I had 2 vacuum lines crossed, There are 3 in the rear of the throttle body, I had the one with the triple into one reversed with the one on the top. Also I had # 7 injector wire that I must have loosened up when I was working on it. Now just wondering how much Antifreeze it takes. The auto parts place says 2 would be enough. Although it is full to where it should be it seems I have to add a bit to keep it on the full when cold level. I picked up a gravity tester and will test it tomorrow just to make sure I got most of the water out of it from flushing it a few times... Thanks guys for all your help once again........
