Thermostat vs Water Pump: Cooling System OE Checks
Thermostats and water pumps belong to the engine cooling system but perform different functions and use different references. The requested component should be stated before a quotation is prepared.
State the cooling-system component
Confirm thermostat, thermostat housing, water pump or another cooling component. Record whether the supply is a component only, a documented assembly or a kit, and do not assume a gasket or hardware is included.
Match the OE to the engine
Verify the exact OE number with model, chassis, engine code, displacement, production range and market. Do not infer opening temperature, impeller design or other specifications unless documented for the exact reference.
Wholesale RFQ checklist

- Documented gasket, seal or hardware contents
- Quantity, packing and destination
- VIN or catalog evidence where alternatives exist
