Download INSTALLATION NOTE: • Always use Honda All Season Antifreeze/Coolant Type 2 and Honda Coolant Concentrate. Using a non-Honda coolant can result in corrosion, causing the cooling system to malfunction or fail. • To avoid burning out the element, do not operate the engine block heater unitl it is installed in the vehicle and you have added coolant. 1. Make sure you have the anti-theft code for the audio system and the navigation system (if equipped). 2. Disconnect the negative cable from the battery. 3. Allow the engine and all cooling system components to cool down. 4.

Remove the tower bar (six nuts, and release the vehicle hose). 6. Remove the vehicle bracket (one vehicle bolt). 7. Disconnect the vehicle connector from the ABS or VSA modulator, and release the harness clip from the vehicle bracket. 8. Get the heater harness.
