111-2378 Radiator — Cat 3116 953B

This is a radiator designed to dissipate heat from the engine coolant, maintaining optimal operating temperatures for CAT engines. It is built to OEM specifications, ensuring efficient heat transfer and robust construction that withstands the vibrations and pressures of heavy equipment operation, unlike a clogged or leaking radiator. Operators may observe the engine temperature gauge rising into the red zone, steam escaping from the engine bay, or a noticeable loss of coolant when this part 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 is typically an engine temperature warning light or gauge reading higher than normal. If ignored, the engine can quickly overheat, leading to reduced performance and potential damage to internal components. Prolonged overheating can cause severe engine damage, including warped cylinder heads or seized pistons.

Installation Tip

Ensure the new radiator is properly flushed and filled with the correct coolant mixture before installation to remove any manufacturing debris. Do not overtighten the mounting bolts, as this can distort the radiator core.

Service Note

Inspect and replace coolant hoses, clamps, and the thermostat when installing a new radiator.
