245-9206 Reseroir Coolant Tank — Cat C15 C18

This reservoir coolant tank is an essential part of the engine's cooling system, holding excess coolant and allowing for expansion and contraction due to temperature changes. Constructed from durable, heat-resistant plastic or metal, it maintains system pressure and prevents coolant loss, unlike a cracked or leaking tank. Operators may observe coolant level drops, steam from the engine bay, or overheating warnings when this tank develops a fault.

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 faulty coolant reservoir tank is often a visible coolant leak, possibly accompanied by a low coolant level warning. If the leak persists, the engine may begin to overheat due to insufficient coolant, leading to steam escaping from the engine compartment. Prolonged operation with a compromised cooling system risks severe engine damage.

Installation Tip

Ensure all old coolant is drained and the mounting points are clean before installing the new tank. Do not overtighten the mounting hardware, as this can crack the plastic tank.

Service Note

Inspect all coolant hoses and connections for leaks or deterioration, and check the radiator cap's condition when replacing the coolant reservoir tank.
