For automatic transmission with cooler lines which drain plug should be used? Radiator came with two. A short and long shaft one.
Dan M December 2, 2017
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!
