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!
