Two. The shop manual calls them both "drive belts", one touches the alternator (top of engine compartment), air conditioner compressor, and water pump. The other (bottom of engine compartment) belt drives the Power Steering pump. There is no timing belt, this car uses a timing chain, which is completely hidden from view in a sealed portion of the engine compartment. The timing chain does not have a scheduled replacement interval and should only be replaced if there is damage which could be indicated by chain noise.
you cant
Toyota Echos have a timing chain rather than a timing belt so there is no need to change it.

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
Mine is a Toyota echo 2000 sedan. It does about 12 to 15 KMPL per 1 petrol litre.

If you are asking if you can tow with a Toyota echo, the answer is yes. See related link for a video of a Toyota Echo towing a small trailer (and off roading).
