1999 Pontiac Trans Am - Bolt-On Inspiration - Part 2
|
After one final check, the back four intake manifold bolts are slipped into the manifold and retained with rubber bands. The manifold is then carefully lifted into the engine compartment and pushed far enough back so that the MAP sensor, brake booster hose, and vacuum lines can be attached. Next, the manifold is pushed into position, and the intake bolts are hand started. Once positively located, the 8mm intake bolts are snugged down with a 11/44-inch air ratchet before being torqued to 44 in-lb on the first pass, and then to the final torque specification of 89 in-lb. The bolts are torqued using a specific tightening sequence that starts on the center bolt of the passenger side and then goes in an alternating bank pattern from left to right and from the center out.
