Information on
leaks
The shaft sealing surfaces inside the coolant pump are lubricated by the coolant, meaning
that a certain leakage flow should always be expected. A low leakage flow is permitted.
The coolant pump requires a certain warm-up time after being started for the first time or
upon restarting after a long period of downtime. An increased leakage flow can occur dur
-
ing this warm-up phase. The leakage flow will normally sink back down to a low level after
the warm-up phase. If this is not the case then contact After-Sales Service.
