Workshop findings: There are coolant marks in the area of the coolant pump housing (Figure 1, position 12), the coolant connector union (Figure 1, position 7) or the thermostat housing (Figure 1, position 14). After cleaning the coolant marks off and performing another leakage test, check for fresh coolant marks on the coolant pump drive (Figures 2 - 6). Figure 1.

Figure 5. Coolant marks on coolant connector union. Figure 6. Areas where coolant marks can be found. Technical Background The coolant pump housing is sealed off with a slip ring seal to the input shaft. To prevent the seal from drying up, a minor coolant leak is necessary to lubricate the seal. If coolant marks are detected in the area of the coolant pump housing during service and there is no customer concern about coolant level/loss, a replacement of the coolant pump housing is not allowed.

Production Solution Not applicable. Service 1. Fully complete the attached worksheet and attach it to the repair order. 2.
