Maintenance and care • an accurate temperature readout from the engine coolant gauge. The engine coolant must be maintained at the correct fluid level and concentration to work properly. If the engine coolant fluid level and concentration is not maintained correctly, damage to the engine and cooling system may result. When the engine is cold, check the level of the engine coolant in the reservoir. COLD FILL RANGE • The engine coolant should be at the "cold fill level" or within the "cold fill range" as listed on the engine coolant reservoir (depending upon application). • Refer to the scheduled maintenance guide for service interval schedules. • Be sure to read and understand Precautions when servicing your vehicle in this chapter. If the engine coolant has not been checked at the recommended interval, the engine coolant reservoir may become low or empty. If the reservoir is low or empty, add engine coolant to the reservoir. Refer to Adding engine coolant in this chapter. Automotive fluids are not interchangeable; do not use engine coolant, antifreeze or windshield washer fluid outside of its specified function and vehicle location. 207
