Timing Chain or Timing Belt?
I am driving a Toyota Avanza 1.3 Manual transmission with a mileage of 87+++ and I am concern about changing the timing belt. But after reading through several articles, I found that my Avanza does not use a timing belt, instead it uses a timing chain. The timing chain, however, does not need regular change (1) and has an almost infinite operating life (2). The only time to change the chain is when the mechanics found it to have been worn out (3). Luckily, the VVT-i technology lessen my worry. It varies the timing and applies oil automatically to the chain (4), resulting in extending its lifespan.
