Stop your car as soon as you safely can and call us. You may have a simple problem like a broken radiator hose and if you continue to drive you could ruin the engine. Let's get it checked out now. Don't drive it to us, stop the car and call us.

Did you know that most of the energy in your gasoline is converted into heat, and it is the job of the cooling system to take care of that heat? 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. 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.

Inside your car's engine, fuel is constantly burning. A lot of this heat goes right out the exhaust system, but some of it soaks into the engine, heating it up. The engine block and cylinder head have many passageways to allow for fluid flow. These passageways direct the coolant to the most critical areas of the engine.

Common Cooling System Terms

  • Thermostat
  • Water Pump
  • Cooling Fan
  • Radiator

The thermostat's main job is to allow the engine to heat up quickly, and then to keep the engine at a constant temperature. It does this by regulating the amount of water that goes through the radiator.

The water pump is a simple pump driven by a belt connected to the crankshaft of the engine. The pump circulates fluid whenever the engine is running.

Like the thermostat, the cooling fan has to be controlled so that it allows the engine to maintain a constant temperature.
A radiator is a type of heat exchanger. It is designed to transfer heat from the hot coolant that flows through it to the air blown through it by the fan.

The cooling system of a car is very complex and involves many components that may break down and need to be replaced during the lifetime of your car. With over 30 years of experience, Target Auto Repair can diagnose and repair any part of this dynamic system. Trust us with your car care needs.
