WARNING: Failure to follow engine block heater instructions could result in property damage or physical injury.

WARNING: To reduce the risk of electrical shock, do not use your heater with ungrounded electrical systems or two-pronged (cheater) adapters.

An engine block heater warms the engine coolant which aids in starting and allows the heater/defroster system to respond quickly. If your vehicle is equipped with this system, your equipment includes a heater element which is installed in your engine block and a wire harness which allows the user to connect the system to a grounded 120 volt A/C electrical source. The block heater system is most effective when outdoor temperatures reach below 0F (-18C).

Prior to using the engine block heater, follow these recommendations for proper and safe operation:

For your safety, use an outdoor extension cord that is product certified by Underwriters Laboratory (UL) or Canadian Standards Association (CSA). Use only an extension cord that can be used outdoors, in cold temperatures, and is clearly marked Suitable for Use with Outdoor Appliances. Never use an indoor extension cord outdoors; it could result in an electric shock or fire hazard.
Use a 16-gauge outdoor extension cord, minimum.
Use as short an extension cord as possible.
Do not use multiple extension cords. Instead, use one extension cord which is long enough to reach from the engine block heater cord to the outlet without stretching.
Make certain that the extension cord is in excellent condition (not patched or spliced). Store your extension cord indoors at temperatures above 32F (0C). Outdoor conditions can deteriorate extension cords over a period of time.
To reduce the risk of electrical shock, do not use your heater with ungrounded electrical systems or two pronged (cheater) adapters.

Also ensure that the block heater, especially the cord, is in good condition before use.
Make sure that when in operation, the extension cord plug/engine block heater cord plug connection is free and clear of water in order to prevent possible shock or fire.
Be sure that areas where the vehicle is parked are clean and clear of all combustibles such as petroleum products, dust, rags, paper and similar items.
Be sure that the engine block heater, heater cord and extension cord are solidly connected. A poor connection can cause the cord to become very hot and may result in an electrical shock or fire. Be sure to check for heat anywhere in the electrical hookup once the system has been operating for approximately a half hour.
Finally, have the engine block heater system checked during your fall tune-up to be sure its in good working order.

How to use the engine block heater

Ensure the receptacle terminals are clean and dry prior to use. To clean them, use a dry cloth.

Depending on the type of factory installed equipment, your engine block heater will use .4 to 1.0 kilowatt-hours of energy per hour of use. Your factory installed block heater system does not have a thermostat; however, maximum temperature is attained after approximately three hours of operation. Block heater operation longer than three hours will not improve system performance and will unnecessarily use additional electricity.

Make sure system is unplugged and properly stowed before driving the vehicle. While not in use, make sure the protective cover seals the prongs of the engine block heater cord plug.
