Construction Note:

Due to new advances in radiator design and technology, this radiator may be constructed from materials that are different from your original. If so, the radiator will still fit and function properly but will be more efficient in cooling.


Radiators may incur bent cooling fins or small imperfections during shipping or manufacturing. A few bent fins or small dents and scratches do not affect the fit or the function of the part. Neither our 60 Day satisfaction guarantee, nor the manufacturer's warranty, cover these types of insignificant damages.

Transmission Cooler Note:

Some radiators are designed to be used on both automatic and manual transmission applications. These radiator may have fittings for an automatic transmission fluid cooler. However these radiators can be used on manual transmission models without issue and require no additional parts or modifications.

Radiator Jeep Wrangler 2002 TJ
I have a 2002 Jeep Wrangler TJ Sport 4.0L 6Cyl 5 Speed manual transmission. I bought it brand new. The radiator began leaking several years ago and I finally got the courage to try and change it myself. After much search and reading reviews I decided on the 1A Auto unit to fit the Jeep. (Pricing and free shipping a big factor in my decision) It installed in an hour. It fits PERFECT, all holes line up and runs at the manufactures recommended temperature. One HUGE bonus with this radiator that I didnt know when I purchased it is the holes for the fan cover are threaded so the factory screws go back in with no alterations. Many reviews that I read said all the aftermarket radiators had non-threaded holes only so you had to bolt on the fan cover. This was a great surprise!!. I recommend this product. 5 Stars out of 5! (This radiator will work on an automatic transmission as well. It does come with 2 sets of inserts for the automatic transmission cooler. I covered these up because they are not needed on the manual transmission.) Ordered it on a late Saturday evening and received it in Texas on Tuesday.

Great Purchase!
This is an excellent product identical to the one I replaced. It fit perfectly and had the added benefit of having several brass fittings included in case the one on the product didn’t work. In the words of The Terminator, “I’ll be back.�
