1. Air cooling: air is circulated over cooling fins cast into the
outside of cylinders and cylinder heads.
2. Liquid cooling: has cavities in the block and head castings
called water jackets
a) Water pump pumps coolant through the system
b) Coolant mixture is designed to prevent rust and
electrolysis: 50% water and 50% anti-freeze.
