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.
Review: OEM quality - OEM fit and finish, and much cheaper than the dealer. Used this for my 2017 Yukon XL. These trucks are easy to R and R the radiator, it's only about a two hour job with basic tools.
