# Service bulletin 144820364771

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.

- Type: Service bulletin
- NHTSA id: 10216669
- Published by NHTSA: 2022\-08\-01
- Manufacturer's number: 144820364771
- Manufacturer's date: 2014\-03\-11
- NHTSA component: FUEL SYSTEM, GASOLINE; ENGINE AND ENGINE COOLING

## NHTSA's summary

The coolant pump is sealed with a slip ring seal to the input shaft. To prevent the seal from drying out, a minor coolant leak is necessary to keep the seal lubricated. Excess coolant from the minor leak is discharged through two leakage holes on the coolant pump. This minor leak is normal operation of the coolant pump, and it is not responsible for coolant loss. This discharged coolant may dry and encrust the coolant pump \(Figure 3\).
