SOURCE: replacing intake manifold plenum
what the hell is the question here? nothing. remove old one and put new one in.
SOURCE: HOW TO REPLACE INTAKE MANIFOLD ON A LINCOLN
answer , very carefully ...
drain coolant , remove and mark all vacuum lines , make a schematic to diagram your hose routing, disconnect and plug all fuel lines, remove distributor and mark location of rotor, disconnect battery, remove any necessary cables, brackets and or accesseries, remove intake mounting bolts, note length of bolts and reference location, pry up on intake , remove intake, scrape old gasket off , must be very clean to reinstall new gasket or you will cause a leak..
SOURCE: intake manifold gasket replacement? radiator has a
nah its pretty simple for the upper intake. 10 to 12 bolts.
SOURCE: need head bolt, intake manifold, and exhaust torque specs
Cylinder Head Bolt Step1- (25 FT.Lbs) Step2(45 Ft.Lbs) Step3(65Ft,Lbs).....Intake Manifold(35Ft Lbs)....Exhaust Manifold Center (20Ft Lbs) All Others (20 Ftlbs).....Thanks
