2003 GMC Sierra 1500 Radiators

Carquest Premium radiators are designed and engineered for maximum performance, using the highest-grade materials to ensure all radiators meet or exceed original equipment (O.E.) fit, form and function. Carquest Premium radiators are built by manufacturers that meet IATF 16949 certified framework, an internationally recognized proof of quality in the automotive industry. Most modern vehicles use radiators with plastic tanks and our parts are engineered with integrated ribbing to prevent damage during thermal cycling. Carquest Premium radiators are also 100% tested to ensure a durable, leak-free cooling system repair.

Product Features:

• Thermal tested under real-life temperature simulations
• High tensile strength aluminum for maximum crimp strength
• Plastic tanks are engineered with integrated ribbing for added strength to withstand cracks, bowing and distortion during thermal cycles
• Thermal expansion slots extend core life and reduce failure rates by allowing improved core expansion and contraction during systematic heat cycles
• Oil cooler designs meet or exceed OE standards, keeping the vehicle¿s engine and transmission performing at optimal conditions
• OEM grade, premium fittings for transmission or engine oil coolers (where applicable)

DENSO is a leading supplier of radiators to OE car makers around the world. Manufacturers rely on our quality and innovation to remain on the leading edge of engine cooling technology. Our OE experience and know-how ensure our products provide unmatched performance, reliability and fitment. Radiator performance is essential for proper engine cooling and function. DENSO’s radiator configurations, tanks, fin pitch, core dimensions and materials meet OE manufacturer’s rigid standards. All DENSO radiators pass our strict durability and function tests. As the result, our radiators deliver reliable performance even under the most demanding conditions. Radiator types: Plastic tank with aluminum core. Plastic tank with copper core. Cross-flow and down-flow configurations. DENSO is known for the unsurpassed quality of its products. Plastic, copper or aluminum components: it doesn’t matter. Our DENSO radiators are dependable, lightweight and made to last. An investment in a DENSO radiator will pay dividends in the long run. Radiators can fail causing leaks or inefficient cooling. This can lead to your engine to run hotter which in turn creates excess wear and tear on the engine. DENSO radiators are designed with our First Time Fit® philosophy in mind. You get radiators that drop in easily without the need for adjustment, brackets or modification of any kind. Our radiators are precision built to provide the right part, the right fit, the first time.

Product Features:

• Fin Pitch – Superior fin waves provide a higher heat transfer.
• Flow Configuration – Available in cross-flow and down-flow configurations.
• Aluminum or Copper Core – Thin-tube construction assures maximum cooling efficiency.

An ACDelco GM Original Equipment Radiator is a heat exchanger located typically in the front of the vehicle, where air can flow through the fins while the vehicle is moving. A modern radiator is made from aluminum and plastic, while older vehicles used copper and brass. These radiators are corrosion resistant with optimal heat transfer characteristics. These original equipment radiators are engineered to fit your specific GM vehicle and will provide the same performance, durability, and service life of your factory original equipment radiator. The radiator is the heart of a vehicle’s cooling system, so get the GM quality you know and trust with ACDelco GM Original Equipment Radiators and Radiator Parts. Stay with the parts brand your vehicle came with and get peace of mind that the fit, form, and function is up to the high standards and specifications of General Motors.
