Derale 3/8" NPT Male x 1/2" Barb Straight Hose Fitting - D98102

Threads into 3/8" NPT, female cooler fitting to attach transmission line.


I ordered three items from etrailer; engine oil cooler D15503, brake controller 5535-3040P, and locking tailgate handle. The brake controller installed without a hitch and only minor issues with the tailgate handle. The engine oil cooler modification fought me throughout but some of the problems I caused myself. D15503 was the wrong kit ordered but was such fine quality I decided to keep the kit and order just the correct sandwich adapter D25772. This adapter fit correctly by the 18mm adapter nut did not. A local machine shop retapped this nut to fit on the engine side of the adapter. Additionally, the initial barb hose adapters from the initial kit will not fit within the new sandwich adapter. Once received everything assembled like clockwork. I do not recommend this method to anyone trying in install on a 2012 Toyota Tacoma. I could not have accomplished this installation without the help of Chris J. Please consider me a loyal customer. Thank you.

  • Recommended Combination Engine Oil and Transmission Cooler for 2011 Ford Explorer Limited
    The first thing you will want to check on your 2011 Ford Explorer is if it has a transmission fluid dip stick and a way for you to add fluid. On many newer vehicles, there is a special tool needed to even check or add fluid that the dealer has. If yours is like that then the cooler would have to be professionally installed. Derale combination cooler # D15902 is the one that I recommend. I have included a link to a video showing an example installation. It is on a different vehicle but...
