["Hydraulic"]
The timing chain tensioner maintains the correct tension on the timing chain automatically, compensating for wear over time and preventing the chain from slapping and jumping teeth. Signs of a failing tensioner include: a rattling noise from the engine on cold startup, cam/crank correlation fault codes, or visible chain slack when the timing cover is removed. Replace the tensioner during any timing chain service to ensure the new chain stays properly tensioned.
