4. Install the new transmission cooler lines.
(1). When the engine is installed, the transmission cooler line bracket requires a new bolt to secure to
the one piece oil pan. Tighten to 10 Nm ± 1.5 Nm (88.5 lb-in ± 13.3 lb-in). (Figure 3)

15. Route the engine ground cable G105 so it crosses back over the harness after the split in the harness
guard. (Figure 10)
16. The original gray pushpin will no longer be in position to secure the bracket to the new one piece oil
pan. Loosely install the harness retainer onto the harness and secure after the engine installation. Refer
to Figures 11-12 for proper installation.
