How it works.
Frequently asked questions.
What happens if the timing belt breaks?
On an interference engine - most modern engines - a broken timing belt lets the pistons hit the open valves, causing major internal damage that often costs a lakh or more to repair. On a non-interference engine the car simply stops running. Either way, replacing on schedule is far cheaper than the alternative.
Does my car even have a timing belt?
Many newer engines, including most current Maruti Suzuki and Hyundai petrol engines, use a timing chain instead, which is designed to last the life of the engine and needs no scheduled replacement. Check your owner's manual or ask your service centre - this calculator applies only to belt-driven engines.
Should I replace the water pump at the same time?
Usually yes. On many engines the water pump is driven by, or sits behind, the timing belt, so most of the labour overlaps. Replacing both together saves a second teardown later and is standard workshop practice in India too.
