Review: 2006 gmc sierra 1500 crew cab with 5.3 - Installed in a 2006 gmc sierra 1500 5.3 crew cab everything worked and no leaks easy installation. Only problem and not really a big problem is the electric fan slip in clips are impossible to make fit right. The electric fans bolt on the top like factory and it’s sits in the bottom of the support anyway and the slide clips aren’t needed. I bent them slightly out the way and it’s been doing great just took a 5 hour trip and it runs cooler than before very please. High quality part will buy again.
Review: Leaking after 7 months - I purchased this radiator August 2025. I just made a report of it leaking and waiting to hear from the seller. I thought it would last me way longer than 7 month...SMH. Hope they can make this right cause it was too expensive not even last a year.

### ⭐⭐⭐⭐ Good product, with exceptions.
*by J***E on July 5, 2026*

Im using this on a 2000 Silverado 5.3 swap. Fits as good as OE radiator. However if you have OE Fans which I do, the E fans will have some clearing issues. Primarily the plastic cover that runs horizontally on top and bottom. You can trim it with dremel a couple of centimeters and fits snug. It increases coolant capacity a bit not by much. I am running 165* thermostat and seem to be keeping up at highway speeds. However the reason for 4 is because they seem to offer 1 year warranty, only after doing research did I find out it is another Chinese company, so getting a warranty is probably never going to happen. I'll update if it doesn't hold up the time test.
