HD Radiator

Use OEM-quality NAPA Heavy Duty Radiators
for fast, easy installation every time.

NAPA Heavy Duty Radiators are manufactured to meet ISO 9001: 2000|FM 70893 quality standards, and are 100% leak tested. They meet or exceed OEM specifications and include accessory packs for easy, drop-in installation on all applicable vehicle models.

Every radiator is built to exact fit for easy installation, and innovative hardware (such as clevis pins) is included so the core can properly expand and contract, and to avoid header leaks.

Stress relief cuts reduce stress on the headers, and a special funnel-shape design permits the tube to be fitted precisely in the header to insure a strong and durable tube-to-header solder joint.

Complete medium- and heavy duty truck radiators from NAPA Radiators are manufactured from the highest quality materials and workmanship.

Each unit is produced using high quality tooling to manufacture the core and tanks. Our complete radiators are 100% pressure-tested and specially packaged to ensure that they arrive in perfect condition—ready for a quick and easy drop-in fit. And there are no core charges. See NAPA store for warranty details.
