Timing Belt

Print

For vehicles frequently idled for extensive periods and/or driven for long distances at low speeds, it is recommended to change the timing belt at 60,000 miles (96,000km).

REMOVAL & INSTALLATION




CAUTION
If the vehicle has an air bag, you must wait at least 30 seconds after disconnecting the battery before doing any work. The SRS has a built-in backup which will allow the system to remain energized for a period of time after the power is disconnected.

2S-E Engine
