CHECKING THE ENGINE COOLANT LEVEL 62sa04a " 1 Reservoir cap 2 Upper line 3 Lower line Look at the see-through coolant reservoir when the engine is cold. The coolant level is satisfactory if it is between the"FULL" and "LOW" lines on the reservoir. If the level is low, add ethylene-glycol type coolant for a proper corrosion protection of aluminum components. The coolant level in the reservoir will vary with engine temperature. However, if the level is on or below the "LOW" line, add coolant. Bring the level up to the "FULL" line. Always use ethylene-glycol type coolant for a proper corrosion protection of aluminum components. See information in the next column. 299
