It Works
Easy drop in replacement for my OEM, it arrived with a broken mounting tab on the bottom, but there was still enough plastic left that I was able to mount it. I do not blame A1 for this since I found the broken piece in the shipping box, I would give it five stars but the packing itself was partly to blame for the busted tab.

Excellent product, great price
My mechanic told me I needed a new �go to� parts place... 1A Auto. When I showed it to my mechanic, he said “order it!� Arrived quickly as usual, and installed easily. Fit perfectly and I no longer have fluids on my garage floor.

My new radiator arrived in the specified time and in excellent condition, thanks to the great packaging. looked great and came with everything needed for a install that went very smoothly. thought i might have had more problems with the cooling system, but the new radiator has the truck running great and took care of the fluctuating temp gauge. thanks !
