The Radiator Coolant Tank Shunt Hose provides an alternate path for the coolant to flow when the thermostat is closed. This allows the coolant to bypass the radiator and circulate directly into the engine. The shunt hose ensures continuous coolant flow and prevents engine overheating, during cold start-ups when the thermostat remains closed. By providing a bypass route, the shunt hose helps maintain optimal engine temperature and prevents potential damage from overheating.Attributes:• Withstands -10 kPa vacuum pressure• Resist high temperatures generated by the coolant circulating through the unitApplications:The Radiator Coolant Tank Shunt Hose ensures proper coolant circulation and prevents engine damage by allowing the coolant to bypass the radiator and flow directly into the engine when the thermostat is closed, maintaining optimal engine temperature.
