What are some of the 2001 jaguar xj8 vanden plas problems?

The 2001 Jaguar XJ8 Vanden Plas is known to experience regular thermostat failure. Some owners report changing the part annually as preventative maintenance. A failed thermostat can cause overheating, a loss of coolant and eventually engine damage. The Vanden Plas' timing chain tensioners are also noted for being faulty. It's advisable to replace the plastic components of the timing gear as well as the water pump before they fail. Cost to re-install a timing chain tensioner ranges from $1,500-$2,000 in parts and labor. The throttle body is prone to getting clogged and d***y prematurely and the Jaguar's valve covers can become degraded with sludge at around 80,000 miles. When buying a used Vanden Plas review these issues before purchasing.
