Lincoln Aviator: Maintenance / Engine Coolant Check
WARNING: Do not remove the coolant reservoir cap when the engine is on or the cooling system is hot. Wait 10 minutes for the cooling system to cool down. Cover the coolant reservoir cap with a thick cloth to prevent the possibility of scalding and slowly remove the cap. Failure to follow this instruction could result in personal injury.
WARNING: Do not put coolant in the windshield washer reservoir. If sprayed on the windshield, coolant could make it difficult to see through the windshield.
WARNING: To reduce the risk of personal injury, make sure the engine is cool before unscrewing the coolant pressure relief cap. The cooling system is under pressure. Steam and hot liquid can come out forcefully when you loosen the cap slightly.
WARNING: Do not add coolant further than the MAX mark.
When the engine is cold, check the concentration and level of the coolant at the intervals listed in the scheduled maintenance information.
Note: Make sure that the coolant level is between the MIN and MAX marks on the coolant reservoir.
Note: Coolant expands when it is hot. The level may extend beyond the MAX mark.
Maintain coolant concentration within 48% to 50%, which equates to a freeze point between -29°F (-34°C) and -35°F (-37°C). Coolant concentration should be checked using a refractometer. We do not recommend the use of hydrometers or coolant test strips for measuring coolant concentration.
