Does the Toyota iQ utilize a timing belt or a timing chain for its engine system?

Question

Accepted Answer

The Toyota IQ comes equipped with a timing chain in its engine, which is a superior choice to a timing belt because it does not require regular replacement. Timing belt replacement is a pricey maintenance task for cars, typically needed every 60,000 to 100,000 miles, whereas a timing chain is durable enough to last beyond 300,000 miles. It is advisable, however, to inspect the chain annually to ensure it remains taut and clear of any obstructions. It is also important to remember that the water pump, which is driven by the chain, may still need to be changed approximately every 100,000 miles to maintain proper circulation of coolant in the engine and prevent overheating.
