Maintenance and Specifications When the engine is cold, check the level of the engine coolant in the reservoir. • The engine coolant should be at the "FULL COLD" level or within the "COLD FILL RANGE" as listed on the engine coolant reservoir (depending upon application). • Refer to scheduled maintenance information 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. Note: Automotive fluids are not interchangeable; do not use engine coolant, antifreeze or windshield washer fluid outside of its specified function and vehicle location. Adding engine coolant When adding coolant, make sure it is a 50/50 mixture of engine coolant and distilled water. Add the mixture to the coolant reservoir, when the engine is cool, until the appropriate fill level is obtained. 226 2005 Five Hundred (500) Owners Guide (post-2002-fmt) USA (fus)
