113-9539 Radiator — Cat 3306 3406

This radiator is a critical component of the engine's cooling system, dissipating heat from the coolant to prevent overheating. Constructed from durable materials designed to withstand high temperatures and pressures, it offers superior heat transfer compared to a clogged or leaking radiator. Observable symptoms of a failing radiator include frequent overheating, visible coolant leaks, or a sweet smell of ethylene glycol.

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 most common symptom of a failing radiator is the engine temperature gauge consistently reading higher than normal. This can progress to coolant loss and visible steam from the engine bay. Prolonged overheating can cause severe internal engine damage.

Installation Tip

Ensure all old coolant is completely drained and the system is flushed before installing the new radiator. Make sure the mounting brackets are secure and the radiator is properly aligned to prevent vibration damage.

Service Note

Replace the radiator cap and inspect all coolant hoses and clamps for cracks or swelling at the time of radiator replacement.
