About Heating and Air Conditioning (A/C)

Cooling System

This system is designed to prevent your car from overheating. The system consists of a radiator, a water pump, the thermostat, hoses and antifreeze/coolant.


A petroleum based solution used in most automobiles to keep the water in your coolant system from freezing in colder climates and boiling in hotter climates. It also protects copper and aluminum parts throughout the cooling system from corroding and deterioration.

Coolant Flush

The technician will remove the drain plug from the radiator and the drain plug on the motor. After draining the coolant, the technician will replace both drain plugs and fill the cooling system with a mixture of 50% coolant/antifreeze and 50% water.

Cooling System – Expansion Tank

This tank is designed to handle the overflow from the cooling system. As the engine heats up, it warms the coolant, which expands and overflows into the tank.


The fan pulls the air from outside the vehicle through the radiator to reduce the temperature of the coolant inside the radiator. The fan is essential to avoid overheating.


This is the primary unit to keep the engine from overheating. Cooler air from outside the engine compartment passes through the radiator’s core that is filled with hot coolant/anti-freeze from the engine. The air reduces the temperature of the coolant/anti-freeze before it returns back to the engine.

Thermo Fan Switch

This heat sensitive device controls when the vehicles electric fan is turned on and off. When the engine gets hot, this device turns the fan on.


The thermostat controls the flow of the coolant/anti-freeze and allows quick warm-up. As the engine heats up, the thermostat opens and allows cooler water from the radiator to travel to the engine.

Water pump

This pump sends anti-freeze/coolant throughout the cooling system and is powered by a drive belt.
