The torque specification is a 2-step process; tighten the vertical lower intake manifold bolts (the four middle ones) to 7 Nm (62 lb in). Tighten the diagonal lower intake manifold bolts (two on each end) to 7 Nm (62 lb in). Tighten the vertical lower intake manifold bolts (the four middle ones) to 13 Nm (115 lb in). Tighten the diagonal lower intake manifold bolts (two on each end) to 25 Nm (18 lb ft).

Upper Intake Manifold
Tighten Bolt/stud 25 Nm (18 ft. lbs)
Notice inch pounds and foot pounds. 62 inch pounds is 5.2 foot pounds.

intake manifold or head gasket? i know head gasket need a sequential order followed by how many degrees and Lbs of pressure. if its on the intake i doubt it needs an specific torque. just try not to crack the intake manifold since its made of plastic.

2.2L Engine & 2.4L Engines
These engines are not equipped with rocker arms. The camshafts directly actuate the valves.

3.1L Engine & 3.4L Engines
When install or connect the check the following:
- Pushrods and the rocker arms. Torque the bolts to 24 ft. lbs. (32 Nm). - Rocker arm cover using a new gasket. Torque the rocker cover bolts to 89 inch lbs. (10 Nm).
- Heater bypass pipe. Torque the screw at the water pump to 106 inch lbs. (12 Nm), the bolt at the cylinder head corner to 18 ft. lbs. (25 Nm) and the nut to 18 ft. lbs. (25 Nm).


About the INTAKE MANIFOLD...
- Intake manifold nuts and bolts and tighten to 89 inch lbs. (10 Nm)
- Pushrods and rocker arms. Torque the bolts to 89 inch lbs. (10 Nm) plus an additional 30 degree turn. - Lower intake manifold. Apply sealant to the threads of the bolts and torque the bolts to 115 inch lbs. (13 Nm).

Hope help.

Position The Intake Manifold Gasket On The Engine.Dowels May Be Provided To Hold The Gasket In Place During Manifold Installation.. The Use Of Silicone Sealer Is Required. Especially Where The Front And The Rear Seals Meet The Side Gaskets On V-type Engines. Installing An Intake Manifold On V-type Engines Can Be Difficult. It Is Critical That You Use Sealer Properly On The Engine To Prevent Vacuum,Coolant, And Oil Leaks.

Start All The Fasteners By Hand Before Tightening. This Will Aid In Bolt Hold Alignment. Then Torque The Intake Manifold Fasteners To Specifications. Use The Specific Torque Pattern Given In The Service Manual.. Basically The Pattern Will Be A Crisscross Pattern

Hello. The torque specs for the intake manifold manifold is 35 ft lbs
