ENGINE COOLANT CHECK
WARNING: Do not remove thecoolant reservoir cap when the engine ison or the cooling system is hot. Wait 10minutes for the cooling system to cooldown. Cover the coolant reservoir capwith a thick cloth to prevent thepossibility of scalding and slowly removethe cap. Failure to follow this instructioncould result in personal injury.
WARNING: Do not put coolant inthe windshield washer reservoir. Ifsprayed on the windshield, coolant couldmake it difficult to see through thewindshield.
WARNING: To reduce the risk ofpersonal injury, make sure the engine iscool before unscrewing the coolantpressure relief cap. The cooling systemis under pressure. Steam and hot liquidcan come out forcefully when you loosenthe cap slightly.
When the engine is cold, check theconcentration and level of the coolant atthe intervals listed in the scheduledmaintenance information. See ScheduledMaintenance (page 449).
Note:Make sure that the coolant level isbetween the MIN and the MAX marks onthe coolant reservoir.
Note: Coolant expands when it is hot. Thelevel may extend beyond the MAX mark.
Maintain coolant concentration within48% to 50%, which equates to a freezepoint between -29°F (-34°C) and -35°F(-37°C). Coolant concentration should bechecked using a refractometer. We do notrecommend the use of hydrometers orcoolant test strips for measuring coolantconcentration.
Adding Coolant
WARNING: Do not add coolantfurther than the MAX mark.
WARNING: Do not add coolantwhen the vehicle is on or the coolingsystem is hot. Failure to follow thisinstruction could result in personal injury.
