Caterpillar 330B E330B Upper Radiator Water Hose 124-1701

The 124-1701 upper radiator water hose is supplied for Caterpillar 330B / E330B excavator cooling system repair. It is used to connect the engine cooling circuit with the radiator area and helps maintain normal coolant flow during machine operation.

This page should focus on the 124-1701 upper water hose application. The old product page used a general hose list with many different CAT hose numbers, which should be removed to keep the 124-1701, 1241701, CAT 330B and E330B product signals clear.

CAT 330B Upper Hose Fitment Notes

The 124-1701 hose should be checked for Caterpillar 330B, 330B L, E330 and E330B excavator cooling system applications. Because hose shape and routing can vary by machine version, the old hose sample should be checked before shipment.

Key Checking Points Before Order

Cooling hoses should not be confirmed only by machine model. The same model series can have different hose routing depending on engine version, cooling package and repair history. The removed hose shape and part number should be checked before quotation.

Part Number Check: Confirm 124-1701 or 1241701 from the old hose record, supplier record or removed sample.

Machine Check: Confirm Caterpillar 330B, 330B L, E330 or E330B application.

Position Check: Confirm that the required hose is the upper radiator water hose, not a turbo air hose or lower water hose.

Shape Check: Compare hose bends, length, diameter and both end connections with the removed sample.

Sample Check: Provide clear photos of the old hose from multiple angles before order.

Radiator Hose Replacement Notes

Before replacing the 124-1701 upper radiator hose, the cooling system should be inspected for aging rubber, coolant leakage, clamp damage, radiator blockage and abnormal engine temperature. A damaged upper hose can cause coolant loss and overheating during excavator operation.

During installation, the hose should be fitted without twisting or forced bending. The clamp position should be checked, and the cooling system should be refilled and tested for leakage after installation. If the old hose failed due to overheating, the thermostat, radiator cap and radiator condition should also be checked.
