1. Antifreeze and/or coolant are both necessary for your coolant system to do its work. This prevents freezing and deters corrosion. Your antifreeze should be changed every 24,000 miles or two years, whichever comes first.

2. The cooling fan - this keeps your engine cool by ensuring air flow through the radiator. This fan may be electric or mechanical, depending on the make and model of car you drive. If these fans fail, your engine may overheat. You mechanic can check the fan belts and drive belts to make sure that these stay in working order. Any cracked or loose belts should be replaced immediately.

3. Your radiator cap should fit snugly; check the fit of your radiator cap annually if not more often. Don't try removing the radiator cap while your engine is still hot - you could seriously burn yourself.

4. The coolant reservoir - this where the fluids which the coolant system relies on go. If these get low, your mechanic will refill your reservoirs to keep everything running smoothly.

5. The thermostat - just as in your home, the thermostat in your car regulates temperature. A poorly functioning thermostat can lead to low energy efficiency, overheating and engine knocking.

Is it normal for water to evaporate from a car engine's cooling system?
A couple months ago, my car's temperature gauge was a little higher than normal, and it ended up being that I had nearly no water in the cooling system. Is it normal for water to evaporate out of the cooling system or is a loss of water nearly always due to a leak?

Secondly, is it bad for the car's water pump to continue to operate when there is low water or no water?
