This is a radiator water tank, an essential component of the engine's cooling system responsible for holding and distributing coolant. It is constructed from durable materials to withstand thermal expansion and contraction cycles, ensuring efficient heat dissipation and preventing leaks, unlike a corroded or cracked tank. Observable symptoms of a failing water tank include visible coolant leaks, a persistent sweet smell of coolant, or a significant drop in coolant level without an apparent cause.

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.
The most immediate sign of a failing radiator water tank is visible coolant leakage, often seen as puddles under the machine or staining on the tank itself. If the leaks are minor, the engine may overheat intermittently, or the coolant level may drop gradually. If left unaddressed, a severely compromised tank can lead to a rapid loss of coolant, resulting in engine overheating and potential severe engine damage.
Ensure all mating surfaces are clean and free of old gasket material before installing the new water tank. Do not overtighten the mounting bolts, as this can distort the tank or damage the sealing surfaces.
When replacing the radiator water tank, inspect the radiator cap, thermostat, and water pump for proper operation.
