Removal procedure
Caution! To prevent injury, do not remove the expansion tank cap when the engine and radiator are hot, as heat maintains pressure in the system. Hot fluid and steam may escape under high pressure.
1. Drain the coolant from the engine cooling system to a level below the thermostat housing. Follow step "Draining and filling the cooling system" in this section.
2. Remove the timing belt. See Section 1B, "Engine Mechanical System - 2.0 Diesel".
3. Remove the timing belt tensioner.
