## Questions & Answers

**Q: My 06 Silverado has an 8.1 liter engine... Will this fit? If not which one do i need?**
A: I have a 2004, same chassis...the radiator fits perfectly, just like the one it is replacing....

**Q: Will fans turn on when A/C is turned on?**
A: Dear customer
The COOLINGBEST radiator fan will automatically turn on when the temperature reaches about 185°

**Q: Will this fit in a 2008 chevy suburban 5.3**
A: The radiator worked on my 2001 Tahoe but with some moderate to major modifications to mounting brackets and the double fans should have independent relays but only one is supplied for both, make sure you take overall height and width measurements,, in my case it WAS NOT a straight forward bolt on situation like it’s supposed to be, if you’re not willing to make moderate mods, don’t get into a situation you’ll regret, I needed the extra cooling capacity but I should’ve went for the 4 row radiator only,, instead of the one with dual electric fans that makes mounting so much more difficult,,,

**Q: Will this fit a 2002 2500hd 8.1 engine with the 5 speed allison transmission? If so does it also have the 5/8 quick connects?**
A: Yes and yes

## Customer Reviews

### ⭐⭐⭐⭐⭐ Awesome!  Perfect fit!  2001 Sierra 2500HD
*by A***R on November 20, 2024*

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
*by M***W on February 13, 2025*

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

### ⭐⭐⭐⭐ Well made and efficient
*by J***S on April 15, 2022*

Easy install. Fits as it should and has lowered my temperature
