Affected Vehicles
Condition
The coolant reservoir is diagnosed to be leaking and intended to be replaced.
Technical Background
May be caused by the coolant hose -1- between coolant reservoir and radiator or the coolant hose -2- between coolant reservoir and engine which may
have internal cracks.
Internal cracks can cause coolant to get inside the coolant hose material and leak from connections to the coolant reservoir (arrows) due to the capillary
effect.
