176-5330 Radiator Hose — Cat 3046 D3G

This radiator hose is a crucial component of the engine's cooling system, facilitating the flow of coolant between the engine and the radiator. Manufactured from high-quality, heat-resistant rubber compounds, it maintains its integrity under pressure and temperature fluctuations, unlike a cracked or swollen hose. Operators may observe coolant leaks, engine overheating, or steam escaping from the engine compartment when this hose fails.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first sign of a failing radiator hose is often visible coolant leakage, especially around the connection points. If ignored, the hose can split or burst, leading to a rapid loss of coolant and severe engine overheating. A ruptured hose can cause immediate engine shutdown and potential damage to critical engine components.

Installation Tip

Ensure the hose connection surfaces on the engine and radiator are clean and free of old gasket material or corrosion before fitting the new hose. Secure hose clamps firmly, but avoid overtightening, which can damage the hose or connection spigot.

Service Note

Inspect and replace hose clamps, and check the condition of the water pump and thermostat when replacing the radiator hose.
