Perfect Fit
September 24, 2017
The radiator was a perfect fit and easy to install. The installation video helped but you don't need to remove the fan. There is plenty of room once the fan shroud is disconnected.
Great service and great product.. I give you a 10

2005 Dodge Ram 1500 - Radiator replacement
October 12, 2017
Saw the same radiator at my local auto parts store for twice as much as I paid for this one, price is 5 star. Unit shipped the same day, I ordered it on a Thursday and it got here on Monday (no Sat Delivery, that cost more than the part). When the part got here, the box looked good, the radiator was sealed with caps and came with mounting hardware. I've never changed a radiator, but I am mechanically inclined; I watched their installation video and it was spot on and very helpful. I also read other reviews from customers that have purchased this particular radiator for a Dodge Ram, someone mentioned that it was "unnecessary to remove the fan before you remove the fan shroud" - so I thought, great, I'll save time and I don't have a wrench big enough to take the fan off anyway. I found out that you cannot remove the fan shroud with the fan mounted - my workaround was taking the 4 bolts off the back of the fan clutch to remove the fan as those bolts are much smaller, this was fairly

received the radiator within four days. installation took about 2 hours. the product was the exact same as the oem that was removed. also the video was very helpful.
Great Value
February 5, 2018
Was a little skeptical about purchasing this online because the price was almost $100 cheaper than local auto chain stores. Quick delivery, no problems installing it myself, and is running fine. It blows me away that it was less than half the price I would have paid buying it locally. I have this company bookmarked for future needs.
Great buy!
February 9, 2018
This was a perfect fit and works great! The installation video was also helpful. I would recommend this radiator if you need a replacement. It was about half the cost of what they wanted at the local auto parts store. Fast delivery!
Great oem match
February 22, 2018
This was a great match to the oem radiator in my 2006 dodge ram 1500. The how to video was very helpful. I will continue to use 1A auto whenever possible.

The radiator was cheaper on this site and the video installation was very helpful. A mechanic was going to charge me $463 total, I purchased radiator, hoses, clamps and antifreeze for $200. 1aauto saved me $263, I’m not a mechanic but I can follow instructions very well. Thanks

Got this for our sons Dodge pickup it is working out fine bolted up easy just like the factory one no problems whatsoever definitely will shop again like we have before thank you for your great products at reasonable prices
Fairly easy repair. (It didn't make me overheat anyway.) Haha get it...
April 6, 2018
Product shipped in a very timely manner. This one has plastic on the sides, the one I was talking out was all aluminum.. So it comes with clip bolt retainers and 2 new rubber mounts. I had to run to the hardware store and get new bolts to fit in the clips. Not a big issue but something to keep in mind. It was my first time replacing a radiator and the 1A Auto YouTube channel sure helped for step by step labor process. Overall very pleased with the whole experience. Definitely recommend to others and I'll be a repeat customer!
Dodge Ram 2500 Radiator installation
November 20, 2018
Looked good and well made, however the clips they provide to hold the fan shroud to the radiator are not the same size as the ones on the OEM radiator which are larger so you have to take the old clips off the old radiator to be able to use the original shroud mounting screw. The problem then is that if you use these OEM screw the are to long and will puncture the radiator tank so you have to cut them down or get shorter screws. This was supposed to be a direct replacement radiator which while close you have to be careful of screw lengths and damaging the tank on the upper right hand side. It you puncture it you'll have to do it all over again. The Video they have for this product is not correct and does not mention the screw length problem.....be carful. Other than the fit problem it works well. Strongly recommend replacing the upper & lower Rad hoses as well as the thermostat while replacing the Rad.

It looks like a very well made radiator and the finish on it is good. It was shipped and packed very well and it arrived without a single ding. It fitted the truck nicely. I gave 4 stars for i have it for only a few weeks but will update later as it goes. So far it works properly.
Perfect Price, Perfect Fit

What a pleasure to have radiator that doesn't leek thank god advanced auto should be ashamed of themselves
Exact fit, good quality, poor packaging
February 18, 2019
I recently swapped out my original radiator with this part from 1A Auto. The new radiator was an exact match to the original part, making installation extremely hassle-free. The only negative was the packaging of the radiator for shipping. The box was ripped and extremely beat up when it arrived. (there were several large holes in the box.) Fortunately, it didn't look like the radiator was damaged, so I didn't bother returning it. Not entirely sure if this damage was due to poor packaging or rough handling in transit.
It worked!!!

Exact fit for my 2004 Dodge Ram 2500. The instructional video also helped, saved me $500 Thanks 1A Auto

Got this radiator to swap out the cracked one on my 2008 Fodge Ram 1500 Mega Cab. Perfect fit better then the OEM super easy to install will be buying upper and lower control arms in the near future. Also cant beat the price and received in 3 business days well worth it!!!

Perfect Fit - Even came with new bushings!
July 29, 2019
My first order and I was not disappointed. The radiator was a perfect fit and came with all the bushings and clips needed. The one from the local store did not have the correct bracket slots for the transmission cooler, this one was exact. It arrived on time and was a great price. I will definitely order from A1 again.

Fit like a dream

Pull out the old leaking radiator from my 2004 ram 2500 that I have been adding fluid to for the past 6 years. New one slid right into place. The new captive nuts didn’t fit my existing bolts so I had to cannibalize the old ones. Now I can sell the truck. Thanks guys, Dean
Worked like a charm
June 15, 2020
The radiator fit as expected, and went in with no issues. Spent more time waiting for the old radiator to drain.
