1Add the coolant type originally equipped in your vehicle.2Use of synthetic or synthetic blend motor oil is not mandatory. Engine oil need only meet the
requirements of Ford specification WSS-M2C930-A and the API Certification mark.3Indicates only approximate dry-fill capacity. Some applications may vary based on cooler size and
if equipped with an in-tank cooler.4Automatic transmissions that require MERCONLV should only use MERCONLV fluid. Refer to
scheduled maintenance informationto determine the correct service interval. Use of any fluid
other than the recommended fluid may cause transmission damage.5Your vehicle’s rear axle is filled with a synthetic rear axle lubricant and is considered lubricated
for life. These lubricants are not to be checked or changed unless a leak is suspected, service is
required or the axle has been submerged in water. The axle lubricant should be changed any time
the axle has been submerged in water.
