502-4178 Coolant Tank — Cat C13

This coolant tank serves as a reservoir for engine coolant, maintaining the correct level and pressure within the cooling system to prevent overheating. Manufactured to meet strict OEM quality standards, it provides a durable and leak-free containment solution, unlike a cracked or corroded tank that can lead to coolant loss. Operators may notice coolant leaks under the machine, a frequently dropping coolant level, or persistent engine overheating if this tank 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 indication of a failing coolant tank is often visible coolant leakage, typically appearing as puddles beneath the machine. If left unaddressed, this loss of coolant will lead to engine overheating and potential severe internal damage.

Installation Tip

Ensure all hose connections are clean and free of debris before attaching them to the new tank to guarantee a leak-free seal. Do not overtighten the mounting hardware, as this can crack the plastic tank.

Service Note

Always replace the radiator cap when installing a new coolant tank to ensure proper system pressure regulation.
