When to change a cambelt on a citroen C5 1997cc 03 plate?

The cambelt on a Citroën C5 with a 1997cc engine typically needs to be changed every 60,000 to 80,000 miles or every 5 to 6 years, whichever comes first. It's important to consult the owner's manual for specific recommendations and to consider the vehicle's service history. If there are any signs of wear, such as cracking or fraying, it's advisable to replace it sooner. Regular maintenance can prevent potential engine damage from a belt failure.
