Good copy of original part. Price at top of the mkt.
Yes very good service I like your company and parts you deliver to me good quality
Arrived on time. Part was exactly what I ordered and a perfect fit.
This fit just like the factory radiator in my 2007 Jeep Commander 5.7L Hemi. The price was great as well as the quality, it has been in for 3 weeks now with now issues.
The radiator was a perfect fit and seemed to be good quality but the packaging was very poor! There was only foam on the ends of radiator inside the box and the over flow tube was poking through the box even and the foam ends were all broken up but the box didn't look beat up from shipping!? I did a leak test on it prior to installing it cause I had my doubts whether it would leak or not! Radiator seemed to be of very good quality so don't make sense to me why packaging is so poor quality!? Thanks, Scott Collins
This was my second purchase from 1A Auto and I'll tell you, I didnt need both sides of my brain to place and complete the whole order process. Enough said. ?? 1A Auto Thanks!!!!
