Looking at an 11 Sri insignia 2l 160bhp. Do they have belt or chain and when does it need changed. It has 183000 miles
Hi Alison,
Assuming you mean the diesel, it has indeed got a timing belt. It must be changed every 150,000km or six years, whichever comes first. If it has never been changed, we urge you to get it done ASAP.

Ask us anything motoring related and please provide as much information as possible so we can give you the most accurate advice.
