What is the torque spec for the intake manifold on a Chevy 305?
Most repair manuals usually call for 25 lbzperiodz/ftzperiodz on aluminum and 45 lbzperiodz/ftzperiodz for iron, but since it's almost impossible to get a torque wrench on the 4 bolts in the center, you'll probably have to use an end wrench and take your best guess at getting them all about the same. Start in the center and work clockwise.
Answer #2For a 96 to 2000 Chevy pickup ( 8th VIN number M ) models were you use the plastic gasket with the rubber seals, you will torque three times in a sequence.
- First to 27 Inch pounds (3 ft. lbs).
- Second to 106 Inch pounds (8 ft. lbs).
- Finally to 11 Foot pounds (11 ft. lbs).
As for the sequence of tightening the bolts. There 8 bolts four in front and four in rear of engine, but you have to look at them as being two rectangular patterns, an inter and an outer.
Rear
5 6
3 2
1 4
7 8
Front
- The inter rectangle beginning with the Front Left bolt closest to the center of the engine, number 1.
- Then you will cris cross to the opposite corner of the inside rectangle, the bolt on the Rear Right bolt nearest the center of the engine, number 2.
- Then the Rear Left nearest the center of engine, number 3.
- Then back to the front right nearest the center of engine, number 4.
- Then the outer rectangle starting with the Rear Left is number 5, from here you will make a z pattern.
- Then cross over to the Rear Right bolt furthest from you which is number 6.
- Then cris cross to Front Left, number 7.
- Then cross over to Front Right, number 8.
Do this Three times starting with 3 Ft. Lbs. then 8 Ft. Lbs. then finish with 11 Ft. Lbs.
If you do not have a Torque wrench, 11 Ft. Lbs. is not Crank down as tight as you can.
11 Ft. Lbs. is Just pretty snug with lots of room to go still, using a regular 3/8 Drive ratchet. Not a breaker bar for more torque.
