This is a water tank, also known as a radiator expansion tank or reservoir, for Volvo articulated haulers. It serves as a storage vessel for excess coolant, allowing it to expand and contract with temperature changes while maintaining system pressure. A cracked or leaking tank will result in coolant loss and potential engine overheating.

Cross-reference part number with serial number before ordering to confirm fitment. Keep original parts until new ones are confirmed correct. Record part numbers replaced for future reference.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The initial symptom of a faulty water tank is often a visible coolant leak or a persistent low coolant level. If left unaddressed, the engine may begin to overheat due to insufficient coolant in the system. Continued operation risks significant engine damage from prolonged overheating.
Ensure all mounting points are clean and free of debris before installing the new tank to achieve a proper seal. Do not overtighten the mounting bolts, as this can crack the plastic tank.
When replacing the water tank, inspect the radiator, hoses, and thermostat for any signs of wear or leaks.
