Freon (refrigerant) is always added to a vehicle’s AC system through the low-pressure side, also known as the low side service port. You should never attempt to add refrigerant through the high side port. Why Freon Goes in the Low Side How to Identify the Low-Pressure Side Tips for Adding Freon Safely Final Answer Freon…
Yes, but only indirectly. In most gas-powered cars, running the heater doesn’t directly consume extra fuel like the air conditioner (AC) does. However, the car’s engine needs to be running to power the heater, and while the engine runs, it burns gas—whether the heater is on or not. How the Car Heater Works Does the…
Indirectly, yes. While your car’s water pump doesn’t directly operate or control the air conditioning (AC) system, it plays a key role in keeping the engine cool. If the water pump fails, it can cause the engine to overheat, and many modern vehicles will shut off or limit the AC system to reduce the load…
Yes, a car’s air conditioning (AC) system sometimes needs to be recharged, but it’s not part of regular maintenance like oil changes or tire rotations. Instead, AC recharging typically becomes necessary when the system loses refrigerant over time or due to a leak. If your AC isn’t blowing cold air like it used to, a…
Yes, the air conditioner (AC) in a gasoline-powered car indirectly uses gas. While the AC system itself doesn’t burn gasoline directly, it relies on the engine—which runs on gas—to power the AC compressor. This extra load makes the engine work harder, causing it to burn more fuel and reduce fuel efficiency. How the AC Uses…
Yes, many Valvoline Instant Oil Change (VIOC) locations offer AC recharge services. If your car’s air conditioning isn’t blowing cold air, Valvoline can check your AC system and recharge it with refrigerant, helping restore its cooling performance. However, not every Valvoline location provides this service, so it’s best to call ahead or check online for…
Yes, a small amount of oil does enter the cylinder, but it is normal and part of the engine’s operation. However, excessive oil in the cylinder can indicate an issue that needs attention. How Oil Gets Into the Cylinder 1. Normal Oil Flow 2. Burned Oil in the Combustion Process When Oil in the Cylinder…
Yes, indirectly. While the water pump and the air conditioning (AC) system are separate components, a failing water pump can indirectly affect your car’s AC performance. The water pump is responsible for circulating coolant through the engine and radiator to keep the engine temperature regulated. If it fails, the engine can overheat, which can impact…
Yes, low coolant is one of the most common causes of engine overheating. Coolant (also known as antifreeze) plays a critical role in regulating your engine’s temperature by absorbing heat from the engine and transferring it to the radiator, where it’s released into the air. If the coolant level is too low, the system can’t…
If you’re in need of windshield washer fluid and wondering whether you can find it at CVS, the answer is yes, many CVS Pharmacy locations do sell windshield washer fluid. However, the selection and availability can vary depending on the store and region. CVS typically stocks basic automotive maintenance products, including fluids for vehicles, especially…
