How Much To Replace Timing Chain Mini Cooper. Get a free detailed estimate for a repair in your area. The cost of timing chain replacement for most cars is on average between £500 and £1,300.

This is made up of the cost of materials for the timing chain and labour for the replacement. Some automakers recommend changing a timing belt between 60,000 and 100,000, others don’t. But not in all cases as paulw123 says they wear sprockets aswell as the chain so i would do it every 150k as precautionary maintenance.
