1640136011 Toyota Radiator Cap Sub Assy

The radiator cap GW0850 only have one pressure unit: 13LBS. It is suitable for most Japanese cars. The double rubber gaskets make the coolant cap fit perfectly. The top of this automobile universal radiator cap is yellow zinc plated. It looks colorful from different angles.  Product Description Most cooling systems from the 1950s onward are pressurized. As they heat up, the coolant and air above it in the radiator expands. The pressure builds up and suppresses the boiling of the coolant. Water can be taken to about 107°C at 4PSI above atmospheric pressure and to 121°C at 15PSI above.   The cap regulates the maximum pressure, preventing damage to the hoses and radiator. After turning the engine off, the system cools and the coolant contracts significantly. The cap therefore has a return valve that admits air from the atmosphere or coolant from an expansion tank, if fitted.   Technical Details Manufacturer Part Number: GW0850 13LBS Application…
