Page 19

NOTE: The following six steps detail the process needed

to loosen and remove the crank bolt. Manual vehicles have

the option of placing a passenger in the car to put the car

in first gear and apply firm brake pressure while turning

the crank bolt. Do not attempt this optional procedure if

the rear wheels are on the ground or vehicle damage and/

or injury could result.

95. Disconnect the oil level sensor electrical connector

from the passenger side of the oil pan.

96. Use a 10mm socket to remove the starter support

bracket bolt.

97. Use a 13mm socket to remove the two starter bolts.

98. Disconnect electrical connector at top of starter, then

use a 13mm socket to remove the nuts retaining power

wires to the starter.

99. Remove and set the starter and bracket aside.

100. Install GM Flywheel Holding Tool #J-42386-A to

prevent the crank from rotating while loosening the

balancer bolt and torque the bolts holding it to 37 ft-lbs.

101. Use a breaker bar and a 24mm socket to loosen and

remove the crank bolt. A long pipe slid over the breaker bar

can be helpful for increasing leverage.

102. Mark off with a piece of masking tape 1.5” from the

tip of the supplied drill bit.

103. Use a 24 mm socket to install the supplied bolt and

reamer guide to the end of the crank.
