PLEASE NOTE: UPS Ground shipping only to the lower 48 states. Sorry no international. Even though this is a synthetic fluid it should be changed on high mileage wagons. I think some owners figure it will last forever. Not so, a partially plugged fitler and deteriorating fluid and lead to early failure of your pump and the power steering unit. REMEMBER - in these cars the same fluid drives BOTH the power steering and the self leveling rear suspension.
This wagon requires a VERY special synthetic fluid - DO NOT USE any other type of fluid!
