Step 1 - Anti-Freeze/Coolant
Fluid is used to dissipate heat away from the engine's block and cylinder heads.
Most engine's have an optimum operating temperature of around 200 degrees Fahrenheit
or about 93 degrees Celsius.
This temperature is maintained using a thermostat which is designed to allow
coolant to flow throughout the system. Normal water boils at 212 degrees Fahrenheit,
or 100 degrees Celsius, and freezes at 0 Celsius or 32 degrees Fahrenheit, where
as coolant boils at 223 degrees and freezes well below 32 degrees. Coolant is also
used to avoid corrosion which can damage vital engine parts such as gaskets and
The cooling system is held under pressure while under operation, between 13-15
psi (pounds per square inch.)
This additional pressure helps the coolant gain additional boiling point temperatures
at a rate of one degree for every two pounds of pressure. For example; when a cooling
system is held at 18 pounds of pressure it raises the boiling point by 9 degrees.
Always check the radiator coolant level when the engine is cold. Visit -
