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
