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.

For automatic transmission with cooler lines which drain plug should be used? Radiator came with two. A short and long shaft one.
Dan M on Dec 2, 2017
BEST ANSWER: Thanks for your question! These radiators come with drain plugs if the factory radiator had one. The drain plug typically is installed on the radiator when you receive it. There may have been other fittings or adapters for the transmission lines and those are sometimes included separately and not installed so the two you have there may be for the other fittings. Thank you!
