Awesome! Perfect fit! 2001 Sierra 2500HD
This radiator installed in a short amount of time and was a perfect fit in my truck. I got the 4 core and it replaced the leaking factory 1 core. It works perfectly and certainly no worries on overheating.

bad welds nd customer service
my radiatiors welds started blowing out coolant after just "2 years" really a year and a half, i contacted on the texting amazon thing and was told they needed an additional 80 dollars for shipping, i would not reccomment as the hoses are 20 years old and rubber and the radiator welds blew, i would go with something that has a better warrenty and customer service

Subpar to design
Fans are not strong at all on highest speed direct power they move half the air as the factory fan and shroud set up very disappointed.. the radiator itself isn't square the bracket that mounts it are 1 inch offset so it sits on truck crooked... construction is ok but definitely not made with specs in mind...wouldn't buy again. Which socks I have 2 other trucks I want to convert to power fans

Chinese Trash
100% my fault. I didn't do my research. This fan lasted less than 3 weeks. Spend the extra money and buy quality from USA.
