Product Overview
The water pump circulates coolant through the engine and radiator. Leakage from the vent area, bearing noise, shaft play, overheating, or visible coolant loss around the pump are common reasons to inspect or replace this component.
Thermo King cross-reference catalogs connect this pump family with 11-9356 / 5D44653G02 and several older service numbers. The engine application is more useful than a broad “Thermo King” label because refrigeration units use multiple diesel engine families.
Key Features & Performance
- Cooling-system circulation: Restores coolant flow through the engine when the original pump is leaking or mechanically worn.
- Application-specific mounting: Designed around the matching engine's mounting face, hub/pulley arrangement, and hose connections.
- Service repair: A practical repair point when pump bearing or seal wear is confirmed rather than replacing unrelated cooling components.
