Technical Service Bulletin To avoid repeat repairs or incorrect repairs, make sure to locate the leak precisely. Ensure that the coolant level has not dropped due to insufficient bleeding during production or due to a previous repair. Note: Traces of coolant (small quantity) on drip cup (refer to figure 1). Due to lubrication/cooling of the seal, up to 3 ml may escape over the course of 100 hours of operation. This is quite normal and does not constitute a reason for a complaint. Figure 1: Traces of coolant on the drip cup.
