The Radiator Header Tank is an integral part of the machine's cooling system. It acts as a surge tank to accommodate coolant volume fluctuations due to temperature changes and houses the filler cap for the system. The tank is made of durable plastic and is connected to the radiator and the rest of the cooling system via hoses.Attributes:• Withstands the high temperatures and pressures associated with the cooling system• Manufactured to precise specifications and is built for durability and reliabilityApplications:The Radiator Header Tank serves as a container to collect coolant overflow and provides a convenient location for monitoring and replenishing the coolant level. The header tank helps prevent air pockets from forming in the cooling system by providing a location for coolant expansion and contraction.
