Inspect the timing chain for stretching prior to removal.

• Rotate the engine while watching timing chain tensioner plunger. When the plunger reaches its maximum extension, stop rotating engine.
• Measure the distance from the tensioner body to the edge of the chain guide as shown in illustration.
• If the distance is greater than 20.5 mm (0.81 in.) inspect the guide shoes for excessive wear.
• If the guide shoes are not excessively worn, replace the timing chain.
