The D21 series offers a small-scale version of big-rig utility, but staying warm on the job requires a functioning heater. When you're dealing with a punctured heater core and foggy windows, order AutoZone's premium heater core replacement for Nissan D21 pickup trucks.

Your Nissan D21 heater core is an essential part of your heating system and is also responsible for operating your defroster. Faulty cores lead to coolants leaks in your cabin, and they often disperse freezing air even when you set your dial to high heat. Plus, all that lingering moisture fogs up your windows and reduces your visibility, but the high-performance D21 heater cores from AutoZone can keep your temperature consistent. The high-strength heating tubes evenly dissipate heat throughout your cabin, and we offer easy Same Day Store Pickup (in most cases) so you can quickly and easily complete the installation.
