Repairing an engine cooling system

A method of repairing a coolant apparatus on an engine for a vehicle, comprising:

• a) circulating a coolant in a closed, free flowing cooling apparatus;
• b) disconnecting and removing a thermostat housing from the cooling apparatus and flushing the cooling apparatus with water or flushing agent after removing a bottom radiator hose or opening a petcock;
• c) reconnecting the bottom radiator hose or closing the petcock, and reconnecting the thermostat housing using a new gasket;
• d) providing an engine at a cold temperature and turning a heater to maximum on the engine;
• e) raising a front end of a vehicle holding the engine to an elevation of about 12-18 inches and using an antifreeze solution to pre-mix a predetermined composition together with an antifreeze solution, pouring the pre-mixed solution into a radiator in the cooling apparatus first, then topping off the radiator with additional antifreeze solution until the cooling system is free of air;
• f) tightening a radiator cap having air release stem;
• g) starting the engine and elevating the engine temperature to a temperature between about 130-210 degrees Fahrenheit, bleeding air out of the radiator cap or bleeder valve as air accumulates until leak/steam has stopped;
• h) stopping and cooling the engine;
• i) starting the cooled engine again and elevating the temperature to about 130-210 Fahrenheit, repeating step (g) two additional times within the same day;
• and
• j) after the third step (g), cooling the engine and reinstalling a new thermostat.
