Phoenix, AZ facts on engine overheating

Although gasoline engines have improved a lot, they are still not very efficient at turning chemical energy into mechanical power. Most of the energy in the gasoline (perhaps 7­0%) is converted into heat, and it is the job of the cooling system to take care of that heat.

The engine in your vehicle generates a lot of heat which would easily damage the engine in just a few minutes if it weren’t for the water pump, radiator, and hoses that make up the cooling system. All automobile cooling systems today are liquid cooled. Water and anti-freeze is pumped through radiator hoses into the engine to cool it down. Then, the heated liquid flows into the radiator to cool off before it returns to the engine to cycle through again.

In fact, the cooling system on a car driving down the freeway dissipates enough heat to heat two average-sized houses!

The primary job of the cooling system is to keep the engine from overheating by transferring this heat to the air, but the cooling system also has several other important jobs.

The engine in your car runs best at a fairly high temperature. When the engine is cold, components wear out faster, and the engine is less efficient and emits more pollution. So another important job of the cooling system is to allow the engine to heat up as quickly as possible, and then to keep the engine at a constant temperature.

If you experience any of the following symptoms, it may be time to take your car in for servicing:

  • Thermostat light coming on or temperature gauge going up
  • AC not producing cool air
  • Liquid leaks onto the ground when your car has been sitting
  • Loose water pump pulley
  • A grinding noise when your engine is running
  • Steam or leaks near the water pump or gasket
  • A sweet smell emerging from the hood area

Although you don’t usually have to worry about freezing temperatures in Phoenix, when combined with water, antifreeze raises the boiling point of the liquid to withstand even higher temperatures – which we do need to worry about. If your vehicle uses a green-colored antifreeze, replace it every two years or 30,000 miles. Extended-life antifreeze is becoming more popular because it lasts up to five years. Just don’t mix the two together – they use chemicals that don’t mix well.
