Perfect Fit - Perfect OEM replacement. Perfect Fit Review: This is the best quality replacement radiator I could find at the best price! - This is the Original Equipment perfect match part for a 2014-2019 Silverado 1500 with a 5.3-litre engine. I called GM parts online and confirmed it was the right radiator for my 2019 Silverado 1500 LD LT 5.3-liter before purchasing and it worked perfectly and is still working great now after a few weeks in use. The job itself is quite a bit of work. It is about a 5-6 hour job depending on your experience level. The desertcart price was the best I could find for this radiator and since it is an OEM part, it fit perfectly. I looked at other radiators and did not find any that did not have several negative reviews about fitment issues. So to me it was worth paying a little more rather than getting a cheap knock off. I had a hard time even finding a house brand radiator in my area and the one store that had this one had it priced way higher making the desertcart price a great value! My truck runs at the perfect temperature now just like when it was new and no more leaks. ## Features - Lightweight; the radiators have a positive heat transfer to weight ratio - Corrosion-resistant aluminum designed core helps optimize the radiators long lasting - Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE) - GM Genuine Parts are designed, engineered and tested to rigorous standards, and are backed by General Motors - GM Engineers design and validate OE parts specifically for your Chevrolet, Buick, GMC, or Cadillac vehicle - GM regularly updates production and service part designs to integrate new materials and technologies ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08MWSRK5J | | Best Sellers Rank | #702,378 in Automotive ( See Top 100 in Automotive ) #2,885 in Automotive Replacement Engine Radiators | | Brand | GM GENUINE PARTS | | Customer Reviews | 4.1 4.1 out of 5 stars (20) | | Date First Available | February 6, 2020 | | Exterior | Machined | | Item Weight | 10.6 pounds | | Item model number | 21927 | | Manufacturer | GM Genuine Parts | | Manufacturer Part Number | 84208890 | | Model | GM Original Equipment | | Product Dimensions | 46.25 x 25.88 x 7.62 inches | ## Images ![21927 (84208890) Radiator - Image 1](https://m.media-amazon.com/images/I/81iyx+-SudL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect OEM replacement.
