To prevent being sprayed with boiling water and superheated steam, it is advisable to wait until the system has cooled before removing the radiator cap or to cover the cap with a sack before' unscrewing it and, before removing the cap altogether, to slacken it to the first notch so that any built-up pressure is dissipated. When the internal pressure is back to normal the cap may be removed with safety. Treat all radiator caps with respect, and if the radiator is boiling, cover the cap with a sack before removing it. — C. J. CROSBIE, Farm Machinery Instructor, Department of Agriculture, Christchurch.
