Service bulletin TSB-17-001-09
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

Listing a model year does not mean every vehicle of it is concerned: the document says which.
| MC1100116 | 2018-12-10. Service bulletin. Coolant pump drain hose. Details The coolant pump is fitted with a radial shaft seal on the oil-side and on the coolant-side is a mechanical seal. Mechanical seals are reliable an durable, yet for technical reasons, they always exhibit minor seepage. The seepage amount is considered to be within permissible limits if the coolant does not need to be topped up between service intervals. The drain hole (arrow in the figure) of the coolant pump is in plain view. Even small, inevitable seepage is noticed and often perceived to be a faulty coolant pump. In many such cases, fault-free coolant pumps are replaced. In order to reduce misdiagnosis and repeat repairs, a drain hose is retrofitted. The hose diverts the seepage away from the field of view to under the engine. Yet large amounts of leakage that indicate a faulty coolant pump will be noticed. |
