Thermostat, Engine Cooling


Thermostat Opening Temp. and Radiator Cap Max. Pressure, Cooper and Cooper S

Thermostat
the thermostat is located in the cylinder head and is retained by a plastic housing (aluminum on COOPER S).
The thermostat begins to open at 89-92�C and is fully open at 103�C.

the MINI COOPER thermostat housing also incorporates the cooling system pressure cap (MINI COOPER S system pressure cap is installed on the expansion tank).

Radiator Cap Max. Pressure



Both models use a pressure cap to pressurize the cooling system to 1.1 bar (16 psi) at which point the cap valve will lift to relieve pressure.
