What is the proper torke for lower intake bolts on 2005 equinox
First, without a picture to guide, orientation of the bolt torque pattern. Looking back toward the engine from the front; Forward refers to the bolt position toward the front of the car / aft is toward the cars rear:
1st bolt is forward, 3rd from the left
2nd is aft, 3rd from left
3rd is forward, 2nd from left
4th is aft, 2nd from left
5th is forward, 1st on the right
6th is aft, 1st on right
7th is forward, 1st on left
8th is aft, 1st on the left
The following is from the GM 2005 Chevy Equinox service manual;
Maximum gasket performance is achieved when using new fasteners, which contain a thread locking patch. If the fasteners are not replaced, a thread locking chemical must be applied to the fastener threads. Failure to replace the fasteners or use thread locking chemical MAY reduce gasket sealing capability.
Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners to avoid damage to fasteners and systems.
IMPORTANT: All lower intake manifold bolts need to be cleaned, free of any foreign material, and reused - only if new bolts are unavailable. Use GM P/N 12345382 (Canadian P/N 10953489) or equivalent and apply to the old intake manifold bolt threads.
IMPORTANT: Manufacturer recommends the center bolts be fully torqued before the diagonal bolts to assure proper seal ability.
IMPORTANT: Lower intake manifold bolts in positions 6 and 7 should be torqued to specification using a crows foot type tool.
Install the lower intake manifold bolts.
a. Tighten the lower intake manifold bolts (1, 2, 3, 4) in sequence to 7 N-m (62 lb in) on the first pass.
b. Tighten the lower intake manifold bolts (5, 6, 7, 8) in sequence to 13 N-m (115 lb in) on the first pass.
c. Tighten the lower intake manifold bolts (1, 2, 3, 4) in sequence to 13 N-m (115 lb in) on the final pass.
d. Tighten the lower intake manifold bolts (5, 6, 7, 8) in sequence to 25 N-m (18 lb ft) on the final pass.
