Heating & Air Conditioning
HOW YOUR HEATING SYSTEM WORKS IN YOUR VEHICLE
Your vehicle’s heating & air conditioning system is based on two simple premises: Temperature and pressure. The system is designed to “cycle” during normal driving, to allow the coolant that’s circulating to do it’s job, and flow where it needs to flow when it needs to be there for you. As the engine temperature rises to nearly 200 degrees, several things happen that open up the system to go into “cool down”, and then cycles back and forth as a means of regulating the temperature.
If there’s a problem with the temperature monitoring, or the pressure in the system (usually between 16-20 psi), then your car may not run/cool the way it should, either causing one of several electronic devices to trigger warning lights, or the car may actually overheat.
Typical Heating/Cooling System Components:
- Cooling fans
- Water pump
- Heater/radiator hoses
- Heater core
- Coolant temp sensor
During a heating & air conditioning system inspection, we’ll examine all components as needed to help uncover the cause of the reported problem/symptoms. If there’s a leak in your cooling system, it can adversely affect the pressure in that system, which dangerously allows the engine to run very hot. It is extremely important to understand that on today’s modern vehicles, you should never drive a car that’s overheating. You might have an otherwise simple hose failure that is relatively inexpensive to repair, but driving it while overheating can cause damage that may cost thousands of dollars to remedy. Summary: If you even think your car is overheating…pull over safely and shut off the engine.
