  1. Install in the reverse order of removal.
  2. Fill with engine coolant.

(Refer to Cooling System - "Coolant")


The coolant must be injected according to the integrated thermal management module (ITM) coolant filling method.

  1. Start engine and check for leaks.


Radiator Leakage Test

  1. Wait for the engine to cool. Carefully remove the coolant reservoir tank cap and fill the radiator with engine coolant. Then, install it on the pressure tester.
  2. Apply a pressure tester to the radiator and apply a pressure of 125.3 - 154.7 kPa (1.28 - 1.58 kgf/cm², 22.44 - 18.17 psi).
  3. Inspect for engine coolant leaks and a drop in pressure.
  4. Remove the tester and reinstall the radiator cap.


Check for engine oil in the coolant and/or coolant in the engine oil.


Integrated thermal management module (ITM) is a device that controls the coolant flow rate according to coolant temperature. At initial startup, the integrated thermal management module (ITM) quickly warms up the engine by controlling the flow of the coolant and this fast warm-up helps improve the fuel efficiency. When the coolant temperature rises, the integrated thermal management module (ITM) adjusts the cooling water temperature by controlling the valves to regulate the flow of coolant through a radiator or heater.
