Clean our the V12 air bleed screw on on XJ6 Jaguars
On the top of the radiator on V12 Jaguars, there is an air bleed tube assembly that allows air to escape from the cooling system. There is a hollow screw that allows air to pass into this system, and this screw is located in the top of the radiator. Over time it gets gunked up, and prevents the air from leaving the system. This can contribute to overheating.
