Do I need to change my Insignia's belt?
Hi I have 66plate vauxhall insignia estate 1.6 tdi does the engine require a timing belt change 79.000miles bought second hand thanks John
Our answer:
Hi John,
The 1.6 diesel engine uses a timing chain, not a belt. It doesn't come with a set replacement schedule as it's theoretically designed for the life of the engine.
