The Torque Specifications for a 3.4L Pontiacby Anne Davis
The 3.4-Liter engine is a member of GM's 60-degree V6 engine family. General Motors, the parent company of Pontiac, began producing members of this family in 1980. GM first manufactured the 3.4-Liter V6 in 1993 and placed it in passenger cars like the Chevrolet Camaro, Pontiac Firebird and Pontiac Aztek.
In the 3.4-Liter V6, the front A/C compressor mounting bolts require 36 foot-pounds of torque to join to the engine block, and the rear ones require 19 foot-pounds. The crankshaft-to-engine-block bolts receive 37 foot-pounds of torque in two steps. The crankshaft position sensor attaches to the engine block with 8 foot-pounds of torque. The rear bolts of the oil pan require 30 foot-pounds and the other bolts require 8.08 foot-pounds of torque to join with the engine block.
The connecting rod joins to the crankshaft with 15 foot-pounds of torque. The flywheel, also known as the driveplate, and the crankshaft attach together with 60 foot-pounds of torque. The engine's vibration damper or hub bolts to the crankshaft with 79 foot-pounds of torque.
To prevent leaks, the oil pan drain plug should receive 18 foot-pounds of torque. The fuel rail joins to the intake manifold with 7.42 foot-pounds of torque. The oil pan requires 8.08 foot-pounds and the oil pump requires 40 foot-pounds of torque to join properly with the engine block. The spark plug attaches to the cylinder head with 11 foot-pounds of torque. The engine's throttle body and intake manifold join together with 18 foot-pounds of torque. The valve-cover-to-camshaft-housing bolts receive 8.08 foot-pounds of torque.
