Engine Coolant Checking the Engine Coolant NOTE: Be sure to read and understand Precautions When Servicing Your Vehicle at the beginning of this chapter. RWARNING The cooling fan is automatic and may come on at any time. Always disconnect the negative terminal of the battery before working near the fan. Your vehicle's coolant protects your engine from overheating in the summer and from freezing in the winter. Check the level of the coolant at least once a month. Simply look at the engine coolant reservoir located in the engine compartment. To locate the reservoir, see the diagram of your vehicle's engine under Engine Type, in this chapter. The coolant additives also protect the entire cooling system from internal passageway corrosion and these additives lubricate the water pump. The coolant should be serviced as noted in the Maintenance Schedule booklet. 217
