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 before it is installed in the vehicle and before you add coolant. Follow steps 29 through 31 and increase the concentration rate of coolant to 60 ±2%. 5. Remove the tower bar (six nuts and release the vehicle hose).
