Radiator Cap Typ-A 1.3 Bar Radium Engineering Black - USA-RAD-18-0076-A13 - The radiator cap is an essential part of an upgraded cooling system. Radium caps are engineered to safely improve cooling efficiency by managing the boiling temperature. A higher radiator pressure effectively raises the coolant boiling point, providing an extra safety margin and preventing air pocket cavitation at the water pump.  NOTE: Traditionally, "radiator" caps are mounted to the radiator but can also be found on coolant expansion tanks Each OEM replacement radiator cap is manufactured from stamped stainless steel for durability. All 18-0076-X1X radiator caps are electroplated black. Unlike OEM caps which use natural rubber gaskets, these radiator caps feature premium silicone sealing elements for long lasting durability.  1. 1.1Bar (16.0psi)2. 1.3Bar (18.9psi)3. 1.5Bar (21.8psi) COMPATIBILITY Below are popular vehicles with their respective radiator cap style used from the factory.
