There is no timing belt in a 2002 Echo. It has a chain, and there is no service interval for it. If it starts making noises, have it checked out. It could last for hundreds of thousands of miles.
Toyota Echos have a timing chain rather than a timing belt so there is no need to change it.
2001 Toyota Echo doesn't have a timing belt.
For my 2002 Echo it is 3.7 Liters with a filter change.

The Echo has a chain. I tried to get a mechanic to change the belt once, he informed me that it had a chain.
Its a chain drive so no need to worry about anything related to timing belt ;) Cheers
I checked the Gates website ( they make timing belts etc. ) and they don't list a timing belt for a 2005 Toyota Echo so it must be a timing chain . I did a Google search and the Toyota website shows the 2000 to 2005 Echo as having a timing CHAIN
