I have a bad radiator in my 07 Monte Carlo SS with the 5.3 can anyone tell me how difficult this is going to be to change the shop that I took it to once $1,020 to do it and I just feel like that's a rip off any help would be greatly appreciated

 

I never did this on a 5.3 LS4, but on the 3.8, it is pretty easy. No real surprises. I want to say part is around $200 (give or take) and time is maybe 2 hours assuming things go right.
