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.

Direct Fit Replacement

Easy Install
I had a leak in my original radiator (2005 Matrix w. 215,000 miles). The shop quoted me nearly $350 to do the replacement. Ordered this radiator for about $62 shipped, got it in a few days. Install took about 45 minutes. Spent another $20 on coolant and at $80 installed Im up and running again. Car runs cool, heater works again. I have bought about a half a dozen parts from 1A Auto. All fit just as they should and performed well. Very satisfied!
