2.2 General Motor Torque Specsby Anne Davis
The 2.2-liter engine belongs to General Motor's Family II, a group of straight-four piston engines originally developed in the 1970s. This engine displaced 134 cubic inches and was placed in such vehicles as the 1982 Chevrolet Cavalier. This engine became the base engine in small pickup models like the S-10 after 1994.
To ensure engine stability, engine bolts must be torqued or bolted down to a certain weight specification under manufacturer guidelines. The bell-housing-to-transmission bolt connects at 55 ft. lb. of torque on the 2.2 engine. The bolt connecting the cover plate to the transmission bolts at 45 ft. lb. Bolts on pre-1995 models connecting the engine block to the transmission, receive 18 ft. lb. and from engines made from 1996 until 1998, this bolt torques to 55 ft. lb. After 1999, it bolts to 35 ft. lb.
The bolt connecting the crankshaft to the engine block bolts at 70 ft. lb. of torque. On pre-1998 models, the bolt connecting the crankshaft position sensor to the engine block torques at 9 ft. lb. and in 1999, it bolts at 7.33 ft. lb. After 2000, the same bolt must be torqued to 5.92 ft. lb. The bolt connecting the cylinder head to the engine block bolts at 46 ft. lb. of torque. The bolt connecting the engine mount to the engine block bolts on at 39 ft. lb. and the oil-pan-to-engine block bolt torques at 7.42 ft. lb.
The connecting rod to crankshaft bolt receives 32 ft. lb. of torque. The flywheel and crankshaft attach together with 55 ft. lb. of torque. The vibration damper-hub connects to the crankshaft with 77 ft. lb. of torque.
The bolt connecting the bracket to the frame must receive 33 ft. lb. of torque. To prevent leaks, ensure that the oil pan drain plug receives 18 ft. lb. and connecting the exhaust pipe to the exhaust manifold attaches with 20 ft. lb. of torque. Connect the fuel rail to the intake manifold with 2.58 ft. lb. and attach the intake manifold to the cylinder head with 17 ft. lb.
