The 1G-FE is an in its VVT-i configuration, meaning a broken timing belt will cause the valves to strike the pistons. On non-VVT-i versions, it is generally non-interference, but proper alignment is still mandatory for the engine to run. Replace the timing belt every 100,000 km (60,000 miles). Step 1: Preparation Disconnect the negative battery terminal. Drain the engine coolant.
