2011 Honda Accord Engine Block Heater Installation Instructions


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. Place a clean drain pan under the radiator drain plug, then remove the drain plug from the bottom of the radiator to drain the coolant. Remove the radiator cap to increase the flow. 5. 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. Using a tape measure, install a wire tie with clip to the heater harness at each of the measurements shown. 9. Disconnect the two vehicle connectors. 10. Release the vehicle harness holder from the vehicle bracket (two hooks). 11. Using a 10 mm hex socket, remove the drain plug from the engine block. Coolant remaining in the engine jackets will flow out the hole when the plug is removed.
