11G176- THERMOSTAT BLANKING SLEEVE

Removal of the thermostat helps to reduce engine temperature; however a thermostat blanking sleeve should be fitted to maintain correct coolant circulation to the entire head. Failure to do so will cause overheating around #3 and 4 combustion chambers-with obviously disastrous results. When the blanking sleeve is used, it is also necessary to blank off the by-pass hose (not found on late heads) between the head and water pump.
