2. INSTALL OXYGEN SENSOR Installation

3. INSTALL CENTER EXHAUST PIPE ASSEMBLY

NOTICE:
* For vehicles with the exhaust heat recirculation system, if the center exhaust pipe assembly needs to be removed and reinstalled, the temperature switch should be replaced. This is because glass material is used in the temperature switch element and the element can be easily damaged in the removal and reinstallation procedures of the center exhaust pipe assembly.
* When installing the heater water hose, ensure that the exhaust heat recirculation system is filled with coolant. Otherwise, the electric water pump may be damaged.
