COOLING SYSTEM Engine (Block) Heater WARNING! Use a solution of half ethylene glycol antifreeze and half water for best heater performance. Do not use more than 65 percent concentration of antifreeze, as a shortened heater life will result. Do not use the heater if there are any signs of problems. Engine block heaters can cause fires resulting in death, personal injury, equipment or property damage if not properly maintained and operated. Regu- larly inspect the engine block heater wiring and connector for damaged or frayed wires. Contact your au- thorized dealer or the manufacturer of the heater if you are in need of repairs or information.
Failure to comply may result in death, per- sonal injury, equipment or property damage. After servicing the cooling system, operate the vehicle for a day or two before using the heater. Trapped air inside the engine needs time to escape. 5 CAUTION Always unplug the block heater be- fore starting your engine. Damage to the cooling system could occur if not turned OFF (unplugged). 5-86 Y53-6077-1B1 (03/17)
