Hyundai Tucson: Cooling System / Integrated Thermal Management Module (ITM)

- Components

1. Integrated Thermal management Module (ITM)

1. Water inlet pipe
2. O-ring

- Description The Integrated Thermal management Module (ITM) is a device that controls the coolant flow rate according to coolant temperature. At initial startup, the 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 ITM adjusts the cooling water temperature by controlling the valves to regulate the flow of coolant through the radiator or heater. - Removal and Installation

   

• Be careful not to damage the parts located under the vehicle (floor under cover, fuel filter, fuel tank and canister) when raising the vehicle using the lift.(Refer to General Information - "Lift and Support Points")

Integrated Thermal Management Module (ITM)

   

• Be careful not to allow the static electricity or any voltage is applied to ITM.

• Keep away the magnetic objects (Ex. magnet) from the ITM.

• When disconnecting the ITM connector, recheck that the engine and all power supplies are shut OFF.

• When connecting the ITM connector, moisture and oil in the connector must be completely removed and foreign materials should not enter.

• When replacing the ITM connector, be sure to use the specified connector.

1.Disconnect the negative battery terminal.

2.Remove the engine cover.(Refer to the Engine And Transaxle Assembly - "Engine Cover")

3.Remove the air intake hose.(Refer to the Intake And Exhaust System - "Air Cleaner")

4.Remove the engine room under cover.(Refer to the Engine And Transaxle Assembly - "Engine Room Under Cover")

5.Drain engine coolant by loosening the drain plug.(Refer to the Cooling System - "Coolant")

6.Disconnect the radiator upper hose quick connector (A).

7.Disconnect the radiator lower hose quick connector (A).

8.Disconnect the heater hose (A).

9.Disconnect the ITM connector (A).

10.First disconnect the ATF warmer hose (A) and then oil cooler hose (B).

11.Loosen the water inlet pipe mounting bolt (A).

Tightening torque : 9.8 - 11.8 N.m (1.0 - 1.2 kgf.m, 7.2 - 8.7 lb-ft)

12.Remove the ITM (A).

Tightening torque : 9.8 - 11.8 N.m (1.0 - 1.2 kgf.m, 7.2 - 8.7 lb-ft)

   

• Do not dismantle the actuator and collector because ITM is supplied as an assembly unit.

   

• When removing the ITM, loosen the bolts and nuts shown in the below.

13.Install in the reverse order of removal.

   

• Always use the new ITM rubber gasket.

• Always use the new water inlet pipe O-ring.

• When installing the water inlet pipe, apply anti-freeze or soapy water to O-ring.

14.Fill engine coolant.(Refer to Cooling System - "Coolant")

   

• Be sure to fill coolant following the ITM coolant filling method.

15.Check the coolant leakage by starting up the engine.

16.Recheck the coolant level.
