id0112q5801200

Warning

•  Never remove the cooling system cap or loosen the radiator drain plug while the engine is running, or when the engine and radiator are hot. Scalding engine coolant and steam may shoot out and cause serious injury. It may also damage the engine and cooling system.

•  Turn off the engine and wait until it is cool. Even then, be very careful when removing the cap. Wrap a thick cloth around it and slowly turn it counterclockwise to the first stop. Step back while the pressure escapes.

•  When you are sure all the pressure is gone, press down on the cap using the cloth, turn it, and remove it.

1.  Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)

2.  Drain the engine coolant. (See ENGINE COOLANT REPLACEMENT [SKYACTIV-G 2.5T].)

3.  Remove the plug hole plate. (See PLUG HOLE PLATE REMOVAL/INSTALLATION [SKYACTIV-G 2.5T].)

4.  Remove the air cleaner, air hose and fresh-air duct component. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [SKYACTIV-G 2.5T].)

5.  Remove the battery and battery tray. (See BATTERY REMOVAL/INSTALLATION.)

6.  Remove the air inlet pipe. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [SKYACTIV-G 2.5T].)

Thermostat Cover Removal Note

1.  Place the cloth on the transaxle case around the area under the thermostat cover.

2.  Slightly loosen the two thermostat cover bolts and use the cloth to absorb the draining engine coolant.

Caution

•  Do not remove the thermostat cover completely at this time because the engine coolant remaining in the engine will drain out.

3.  After the engine coolant stops draining, remove the thermostat cover.

Thermostat Installation Note

Caution

•  Do not apply oil (such as engine oil, ATF) to the rubber seal part of the thermostat. Otherwise, the O-ring could swell causing a seal malfunction.

1.  Install the thermostat with the jiggle pin aligned with the notch of the water outlet.
