is timing belt the common problem for that model
how much will cost to change timing belt, my car still running good . on 2002 Toyota Echo
First this engine does not have a timing belt it uses a timing chain, as far as replacement cost suggest as a Toyota dealers. I have had two echos 2003 200,000 + miles and a 2005 with 97,000+ miles and neither one has gotten to a point of needing a timing chain.
Toyota Echo does not use Timing Belt. It uses a chain - so you are in luck. No need to change it. :-)
