Timing belts need to be changed every five years or usually between 30,000 and 60,000 miles (whichever comes first). Chains last longer, needing to be changed at around 100,000 miles. Sometimes they’ll even last the lifetime of the engine.
Space does not allow us to mention all the diesel engines that have timing chains rather than belts, (in brief, all BMW, Mercedes-Benz, Honda, Kia, Hyundai, Subaru, Fiat/Vauxhall 1.3, plus more) but maintaining good chain life is mostly related to regular oil services.
How long do diesel timing belts last?
Depending on what schedule you may read, including information distributed by the manufacturers themselves, the average life span of a timing belt is between 60,000 and 105,000 miles or after 7 to 10 years regardless of mileage.
The belt is attached to a series of sprockets and pulleys in your engine, which determines exactly when the valves open to optimise your engine’s performance through the most efficient burning of the air/fuel mixture. Some diesel engines also have fuel pumps that are driven and ‘timed’ by the same belt.
