Rediator change
Great service ! Ordered the radiator for my 2004 Jeep Liberty and had id within a week. The install was fairly simple but without a 1A Auto video as a guide, the removal was a little difficult. Especially not knowing the little nuances that came up as I tried to remove the old one. Ive done others but not on a vehicle that was this young. The install was fairly straight once you know where all the parts that attach go. All in all, this was for someone that has some experience working with their hands.

Just as advertised
radiator arrived when they said it would. Fit as it should. One little problem though. one of the square nuts to attach electric fan had came out and was lost. Took one out of the old radiator and good to go. Im sure it was a fluke deal. Would buy the same radiator again

Customer Q&A
Ask a question to 1A Auto customers who purchased the product
how hard are these to install?
Jim L December 20, 2016
Not difficult at all. Only problem I had was with removing the lower radiator hose. I ended up cutting it off and replacing with a new one.
Juan C December 20, 2016
Not hard at all. Be sure to watch the install video, its very helpful. Took me about an hour.
David W December 20, 2016
Based upon the application, you will need to remove certain pieces such as the upper and lower radiator hoses. You will also be required to place other components to the side based upon your vehicle set up, and the video showing the replacement should assist with this procedure.
Alex P December 20, 2016
It took about 30 minutes and it was not very difficult. Just take you time and dont damage the aluminum fins when you insert it in place.
Ed M December 20, 2016
Very easy. Not my first radiator swap, bought one from napa 5 years ago, so I was already familiar with the process. 1A Autos fit like the factory. Still works great 2 years later.
Richard P December 21, 2016
Very easy, I did it without removing the grill, but would be faster with the grill off to access the bolts to the power steering cooler. Save the rubber grommets off the old radiator as the new one does not include these. Drill the rivets out on the bracket for hood latch, may have to bend it out of the way a bit, disconnect all lines and hoses, remove any bolts connecting the evap coil and it will lift right out, Carefully install radiator in reverse. You can use small bolts/nuts to replace rivets on bracket or find the large rivets at the auto part store.
Michael R December 22, 2016
The product description says that it "does not include mounting brackets for the automatic transmission oil cooler." Are these brackets available for purchase or can they be removed from the old radiator?
Bernie C February 4, 2018
You would have to swap over the original brackets to the new radiator.
