Engine Torque Specifications

TORQUE





2.4L, EDG, ED3

CYLINDER HEAD






CAUTION: This engine was built with 2 different style cylinder head bolts. Each style bolt requires a different torque value. The bolts can be identified by the short bolt head (1) and the long bolt head (2).





If your bolt has the short head (1), use the following torque specifications:
First: All 30 Nm (25 ft. lbs.)
Second: All 61 Nm (45 ft. lbs.)
Third: All 61 Nm (45 ft. lbs.)
Fourth: All an additional 90°

CAUTION: Do not use a torque wrench for the Fourth step.

If your bolt has the long head (2), use the following torque specifications:
First: All 30 Nm (25 ft. lbs.)
Second: All 73 Nm (54 ft. lbs.)
Third: All 73 Nm (54 ft. lbs.)
Fourth: All an additional 90°

CAUTION: Do not use a torque wrench for the Fourth step.

HEAD BOLT REUSE/REPLACE










The cylinder head bolts must be examined BEFORE reuse. If the threads are necked down the bolts must be replaced.

INTAKE MANIFOLD






Camshaft Bearing Cap






Main Bearing Cap






CAUTION: There are different sets main bolts supplied with this engine. Each bolt set has a different torque value and engine damage could result if bolts are not torqued correctly. The bolts are not interchangeable.







If your bolt heads look like this (1,2), go to step A. If your bolt heads do not look like this (1,2), go to step B.

A. Tighten bolts using a three step method, in the sequence shown.
- Tighten bolts to 15 Nm (11 ft. lbs.)
- Tighten bolts to 27 Nm (20 ft. lbs.)
- Rotate an additional 45°.

B. Tighten bolts using a three step method, in the sequence shown.
- Tighten bolts to 15 Nm (11 ft. lbs.)
- Tighten bolts to 45 Nm (33 ft. lbs.)
- Rotate an additional 45°.

OIL PUMP [Balance Shaft Module (BSM)]






CAUTION: There are two different Balance Shaft Module (BSM) to engine block bolts used. 180 mm bolts with a lock-patch on the threads or 185 mm bolts without lock-patch. Do not reuse the 180 mm bolts. Always discard 180 mm bolts after removing. Failure to replace these bolts can result in engine damage. The 185 mm bolts are reusable. Install the same length bolts that were removed and use either four new 180 mm bolts or four 185 mm bolts.










The 185 mm (7.283 in.) length bolts must be checked for stretching. Check the bolts with a straight edge for necking (2). If the bolts are necked down, they must be replaced.

For new 180 mm bolts

Tighten new 180 mm BSM mounting bolts as follows:
a 15 Nm (11 ft. lbs.).
b 33 Nm (24 ft. lbs.) .
c Rotate bolts an additional 90° .

For 185 mm bolts

Tighten 185 mm BSM mounting bolts as follows:
a 15 Nm (11 ft. lbs.).
b 29 Nm (22 ft. lbs.).
c Rotate bolts an additional 90°
