Removal and Installation
  • To avoid damage, carefully disconnect the wiring connectors by holding the connector body.
  • Label all wires and hoses to avoid incorrect connection.
Water Temperature Control Assembly
  1. Disconnect the negative battery cable.
  2. Remove the engine compartment cover. (Refer to Engine and Transaxle Assembly - "Engine Compartment Under Cover")
  3. Loosen the drain plug and drain the engine coolant. (Refer to Cooling System - "Coolant")
  4. Remove the air cleaner assembly. (Refer to Intake and Exhaust System - "Air Cleaner")
  5. Disconnect the upper radiator hose (A) and lower hose (B).
    When installing the radiator hoses, install them as shown in the illustrations.
  6. Disconnect the WTS and gauge connector (A).
  7. Separate the engine wiring protector installed on the water temperature control assembly.
    When installing, be sure to install the original wiring protector mounting bolts. If other bolts (longer or larger) are installed, the water temperature control assembly may be damaged and coolant leakage may occur.
  8. Disconnect the throttle body coolant hoses (A).
  9. Disconnect the heater hoses (A).
  10. Remove the water temperature control assembly (A).

    Tightening torque: 19.6 - 24 N·m

  11. Install in the reverse order of removal.
  12. Fill the radiator with engine coolant and check for leaks. (Refer to Cooling System - "Engine Coolant")
  • Fill the engine coolant.
  • Fill the radiator and the coolant reservoir with engine coolant.
  • Bleed air from the cooling system.
  • Start the engine and let it run until it warms up (until the radiator fan has cycled 3 or 4 times).
  • Turn the engine off. Check the coolant level in the radiator and add coolant if necessary. This allows trapped air to be removed from the cooling system.
  • Tightly close the radiator cap, then restart the engine and check for leaks.
  • Clean the battery terminals and cable terminals with sandpaper, reconnect them, then apply grease to prevent corrosion.
Water Outlet Pipe
  1. Remove the intake manifold. (Refer to Intake and Exhaust Systems — Intake Manifold)
  2. Remove the water temperature control unit. (Refer to Cooling System - "Water Temperature Control Assembly")
  3. Remove the water center pipe (A).

    Tightening torque: 9.8 ~ 11.8 N·m
    Do not reuse the water pipe O-ring.
  4. Install in the reverse order of removal.
