Have you ever lifted the hood of your car and noticed a label calling out specifications for your mobile A/C system? Did you ever wonder why it was there? Your car’s manufacturer put that label under the hood to provide necessary information for your service professional. Avoid removing this label from your car.
If your car’s A/C system is not cooling you off in a reasonable time frame to make you happy, take it to your service professional for an A/C check-up. Here’s what he or she will look at:
Thermostats open and close with changes in engine temperature, and sometimes become stuck. If stuck open, the engine never warms up properly and there is little or no heat from the heater. A stuck-open thermostat can also be a cause of poor fuel economy.
Stuck closed, a failed thermostat can cause engine overheating because the coolant
Extreme heat is still gripping much of the United States and summer long-distance travel is still on many people’s agenda. In order to make it through the rest of this record breaking hot summer make sure to have your service professional check your engine cooling system belts and hoses.
The cooling system hoses and belts can deteriorate over a period of time. The
Over the last few years, due to trends in styling, many newer cars do not have conventional grills up front. Very often, a closed panel resides, or the hood extends down to where a grill would have been. But all vehicles still depend on air passing through the radiator to provide engine cooling, and also for A/C system operation.
Many vehicles now have electric cooling fans that do not operate until necessary, when the engine coolant temperature climbs above a certain point.
The heater core is located inside the passenger compartment of the vehicle, quite often very deeply buried inside or under the instrument panel, or behind some other type of interior trim panel. Some SUVs and vans have two heater cores, a front and a rear.
A radiator has 2 tanks, one containing the inlet and one containing the outlet. These tanks, which can be at the top and bottom or sides, are usually made of aluminum, brass, copper, or plastic (most newer vehicles use the plastic type).
This particular cabin air filter came from a Volvo class 8 truck and it hadn’t been changed for three years! It was retired in favor of a replacement. We wanted to share this photo with you to show you how cabin air filters do their job
The water pump is the heart of the cooling system. It circulates the coolant through the engine, radiator and heater core. These days, certain vehicles (like some SUVs, vans and most hybrids) often have more than one water pump, and the auxiliary pumps are usually run by electric motors and controlled by a computer.
