Answer 2

The same engine in the 2004 - 2007 Malibu, but with 3.5 or 3.9L displacement, are torqued to 44 ft lbs in the first step and are tightened an additional 130 degrees in the second step. If you are standing so the front of the engine is on your left, number the bolts across the top, from the front to the back (left to right) as 5-3-2-8 and the bolts across the bottom as 7-1-4-6 This should produce a diagram 5-3-2-8 7-1-4-6 The bolts are torque-to-yield on this engine, so it is essential to use new bolts.
