CATCooling System

1643599 Radiator — Cat 315B 317B

This radiator is a critical component of the engine's cooling system, responsible for dissipating heat from the coolant. Constructed from durable materials designed to resist corrosion and pressure, it ensures efficient heat exchange unlike a radiator with clogged passages or leaks. Operators may notice a rapid increase in engine temperature, steam from the engine bay, or coolant loss when this radiator is failing.

Installation & Application Notes

Flush cooling system with distilled water before refilling. Use pre-mixed coolant — never plain water, which causes corrosion. Pressure-test system after any cooling repair. Check thermostat by immersing in hot water — should open at rated temperature.

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 is often a noticeable increase in engine coolant temperature, especially under load. If ignored, this can lead to severe overheating, potentially causing significant engine damage. Continued operation with a compromised radiator risks catastrophic engine failure due to sustained high temperatures.

Installation Tip

Ensure all sealing surfaces are clean and free of debris before installing the new radiator to prevent leaks. Do not reuse old radiator clamps, as they can lose their tension and lead to coolant leaks.

Service Note

Replace the radiator cap and inspect all coolant hoses and the thermostat when installing a new radiator.
