Engine Coolant:
- An engine coolant (also called an antifreeze) is a special fluid that runs through your engine to keep it within its correct operating temperature range.
- It is made from either ethylene glycol or propylene, water, some protection additives and is usually green, blue or even pink in colour.
Engine Coolant properties:
An efficient cooling system removes 30 to 35% of the heat generated in the combustion chamber.
- Coolant should remove heat at a fast rate when the engine is hot.
- Coolant should remove heat at a slow rate when the engine is started until the engine reaches its normal operating temperature.
- Coolant should not remove too much heat from the engine. Too much removal of the heat decreases the thermal efficiency of the engine.
- It should have a Low freezing point
- It should have high thermal conductivity.
- It should have high thermal stability.
- It should have a high thermal specific heat
- It should circulate freely in the coding system.
- It should prevent frequency and rust formations.
- It should be reasonably cheap.
- It should not waste by vaporization.
- It should not deposit any foreign matter in the water jackets/radiator.
