Tell Us More About Your Chevrolet Avalanche. View all models

AutoZone carries hundreds of thousands of parts and accessories.

Select your Year, Make, Model and Engine to find those that fit your vehicle.

Your Chevrolet Avalanche offers a great mix of utility and comfort. But, your comfort during cold-weather drives takes a hit when your truck's climate control system isn't working the way it should. If your Avalanche's windows are fogging up for no reason, you may have a malfunctioning heater core – a key component that permits your heater and defroster to function.

Other symptoms of a bad core include, a sweet smell inside your vehicle, coolant pooling on the passenger-side floor and very cold or warm air coming from your heater. AutoZone carries Avalanche heater cores to get your heater working correctly again. With trustworthy advice provided by helpful staff, along with our Loan-a-Tool Program, we make completing your project a snap.
