The replacement went in a whole easier than the old one came out since I didnt have a book or video on it. My daughter and I had it replaced within 6 hours and thought we did a good job for novices.

Radiator for 1999 Buick Best price every
This was the best purchase I made. To be honest it was the best price, after searching many different auto part stores. When I was told the day it would be delivered it came right on that day. I recommend 1A Auto to my family and friends. Will continue to buy my auto parts from 1A Auto
