3.4L Torque Specs

In the 3.4L V6, the crankshaft bolts to the engine block with 37 ft-lbs of torque. Both the crankshaft position sensor and the camshaft position sensor require eight ft-lbs of torque to attach to the engine block. The cylinder head bolts require two steps to receive 44 ft-lbs of torque to join with the engine block. The large bolts joining the front plate and the engine block require 35 ft-lbs of torque and the small bolts joining them require 20 ft-lbs. The rear bolts of the oil pan require 20 ft-lbs and all other oil pan bolts require 8.08 ft-lbs of torque to attach to the engine block.

The connecting rod attaches to the crankshaft with 15 ft-lbs of torque delivered in two distinct steps. The flywheel-to-crankshaft bolts require 60 ft-lbs of torque. The engine's vibration damper or hub attaches to to the crankshaft with 79 ft-lbs of torque.

The camshaft housing in this engine attaches to the cylinder head with 20 ft-lbs of torque. To prevent leaks, the oil pan drain plug should receive 18 ft-lbs of torque. The engine block-to-transaxle bolts require 55 ft-lbs of torque. The studs joining the exhaust manifold and the cylinder head receive 13 ft-lbs of torque. The bolts on 3.4L V6 engines manufactured in 1995 that join the exhaust manifold and the cylinder head require 18 ft-lbs of torque, and those manufactured after that year require 9.67 ft-lbs. The intake manifold nuts and bolts receive 30 ft-lbs of torque to attach to the cylinder head. The spark plug attaches to the cylinder head with 11 ft-lbs of torque.
