Automobile batteries store chemical energy rather than electrical energy. Aside from working as a power source for electric cars and a starter for gasoline cars, the battery also works as an electrical equalizer, meaning that dangerous voltages are absorbed by the battery from the car’s electrical system. This protects the vehicle from being damaged by transient electric charges.

In Tucson, the extreme weather conditions can shorten the life of a battery. What this means is you’re not going anywhere without a properly working battery. Think of Cost Less Auto Parts first when you have battery needs. We’ll get you started. We carry:

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

The water pump uses centrifugal force to send fluid to the outside while it spins, causing fluid to be drawn from the center continuously.
The fluid leaving the pump flows first through the engine block and cylinder head, then into the radiator and finally back to the pump.

If your water pump needs replaced, we have a massive stock of water pumps to match your need, including new and remanufactured selections.

Serpentine belts make the engine go round. Check out Cost Less Auto Parts for all of your serpentine belt needs.

Automotive oxygen sensors—better known as O² sensors–make modern electronic fuel injection and emission control possible. They help determine, in real time, if the air–fuel ratio of a combustion engine is rich or lean. Since oxygen sensors are located in the exhaust stream, they do not directly measure the air or the fuel entering the engine.

When an O2 sensor fails, you’ll be heading our way to pick up the proper replacement part—we’ll be ready for you!
