Mazda 3 Heater Core

Keeping your 3 in top shape is your top priority.

The vehicle in your driveway is head and shoulders above the rest when it comes to all the cars, trucks, and SUVs currently being driven today. You purchased your 3 because its best-in-class value and economical pricing struck a chord inside you; so why would you settle for second best when it comes to the highest quality auto parts? Auto enthusiasts know that dependability is built into each Mazda, and understand that only top quality replacement 3 parts will suffice when maintenance needs to be done. Anyone who drives a Mazda knows that when it comes to repairing their vehicle only the highest quality replacement parts will do.

Why Heater Core replacement is so important.

Believe it or not, your car or truck's heating system is closely tied to its engine cooling system. The engine of your Mazda 3 circulates liquid coolant throughout the block to absorb heat, and sends this liquid to the heater core (a small radiator) through a heater supply hose when you want to warm your vehicle's cabin. Your heater core sits inside a heater box, mounted behind your glove compartment, and you can find it by following the two heater hoses towards the passenger side of the firewall. To make a long story short, your Mazda 3 heater core acts like a radiator; in that it uses the engine coolant to emit heat for the blower motor to propel into the inside of the car.

Good products, great prices, the best people.
