1993 Pontiac Lemans-Import 1.6L TBI SOHC 4cyl

Application:

Cylinder head bolt torque sequence

Note :

Torque sequence ----------------

| 8 4 1 5 9 |

| 7 3 2 6 10 |

----------------

Step 1: Torque in sequence 18 Ft/Lbs

Step 2: Torque in sequence 60 degrees

Step 3: Torque in sequence an additional 60 degrees

Step 4: Torque in sequence 30 degrees

recheck final torque in sequence

>*** CAUTION *** <

Engine uses Torque To Yield head bolts (TTY) that

permanently stretch during the initial installation.

New head bolts must be used when cylinder head is

replaced or re-installed to obtain proper torque.
