Does the 2007 Toyota Corolla have a timing belt or chain?

All configurations of the 2007 Toyota Corolla include a 1.8L 4Cylinder engine, which is driven by a timing chain. Depending where Your school of thought falls, this can be either a good thing or a bad thing. On one hand, timing chains are designed to last for 250,000 to 300,000 miles, so it's likely that the rest of Your Corolla will fail before the timing chain does. On the other hand, if something goes wrong -- You could be in for a repair in the $3,000 range. Timing belts tend to nickel and dime You, but they're by and large much less expensive to fix. Since chains aren't designed to be replaced, the swap is much more labor intensive. To help mitigate this, it's important to take good care of Your timing-chain-driven engine, so hopefully no stretching or other damage occurs.
