WARNING: This page is about a different variant/trim than selected.
Inspect the timing chain guides (3, 7) and timing chain tensioner pivot arm (1) for cracking or wear.
- Replace the timing chain guides if wear exceeds 1.12 mm (0.045 in) depth on the chain guide surface.
- Inspect the timing chain tensioner (13) shoe for wear.
- Replace the timing chain tensioner if shoe wear exceeds 1.12 mm (0.045 in) depth on the chain guide surface.
- Inspect the timing chain (4) and actuators (2, 5) for wear.
- Inspect the camshaft actuator faces for signs of movement.
- Inspect the camshaft actuator teeth and chain for signs of excessive wear, chipping, or seizure of the timing chain links.
- Inspect the timing chain oil nozzle (6) for collapse or cracks at the bolt boss. Discard and replace the oil nozzle body if it is damaged.
- Verify oil nozzle oil flow with compressed air.
- Inspect the timing chain tensioner (13) for scoring or free movement.
- Inspect the timing chain tensioner washer. If damaged, replace the timing chain tensioner.
- Inspect the crankshaft sprocket (12) for excessive wear or chipping.
- Inspect the balancer chain (8) for wear.
- Inspect the balancer chain guide (11) for wear.
- Inspect the balancer chain tensioner (9) for wear.
- Inspect the balancer shaft driven sprocket (10) for wear or chipping.
