1993 Ford Bronco Upper Intake Manifold Torque Sequence Diagram - 12-18 Lb Ft

Exploded intake manifold bolt diagram with numbered fasteners and a 16-24 Nm (12-18 lb-ft) torque specification.

AI caption · Photo 55 of 69

This document is a line-drawing diagram showing the bolt tightening sequence for attaching an upper intake manifold to a lower intake manifold. Six bolts are identified with numbered callouts (1 through 6), indicating the order in which the fasteners should be tightened. Callouts 1 and 2 point to two long bolts at the top center of the manifold; callout 3 points to a shorter bolt on the upper left; callout 5 points to a stud/bolt at the far left; callouts 4 and 6 point to studs on the lower right side of the manifold. The only text on the document is the torque specification printed beneath the illustration: 16-24 Nm (12-18 Lb Ft). A reader can learn the correct tightening order for the six upper-intake fasteners and the torque value to apply to each. The document itself does not state a year, make, model, or engine, but it was uploaded to a 1993 Ford Bronco gallery as 'Upper to lower Intake Torque Sequence' and accompanies other torque-spec scans (head torque, intake bolt torque) in the same album.
