KHH10850 Radiator Coolant Expansion Overflow Tank for Case CX290B, CX300C, CX350C

   Thank you for choosing SPARKLING MACHINERY.

   The KHH10850 radiator coolant expansion tank is manufactured from premium high-density polypropylene (polymer compound) engineered to survive extreme under-hood temperatures, constant pressure fluctuations, and chemical exposure from modern diesel coolants. Replacing a cracked, yellowed, or leaking expansion tank stops chronic coolant loss, prevents air from entering the cooling system, and protects your heavy-duty engine from overheating under maximum workloads.

The SPARKLING KHH10850 Radiator Coolant Expansion Overflow Tank is a reliable replacement component designed for Case CX290B, CX300C, and CX350C excavators. It supports the cooling system by receiving excess coolant as the engine temperature rises and returning coolant when the system cools down. This helps maintain a stable coolant level and reduces the risk of overflow, coolant loss, and engine overheating.
