Replacement Interval Guide
- Jaguar recommend replacement every 144,000 miles or 10 years (tensioner pulley must also be replaced).
- The previous use and service history of the vehicle must always be taken into account.
Check For Engine Damage
CAUTION: This engine has been identified as an INTERFERENCE engine in which the possibility of valve-to-piston damage in the event of a timing belt failure is MOST LIKELY to occur A compression check of all cylinders should be performed before removing the cylinder head.
