Used to remove transmission cooler line check valve. Amazon had the best deal online.

This does not fit Jeep Patriot even though both Amazon and Hayden says it does. Threads are 5/8" - 18 with 45% flare. The threads on the Jeep are 9/16" -18 I then ordered the 396 which has the correct threadings, but the flare angle is incorrect. Very frustrating.

Didn't actually work for my application ('98 Jeep ZJ Grand Cherokee 4.0), even though the fit guides say they do. Jeep changed the radiator in the '98 ZJ, and used different transmission line fitting too, so these didn't fit. But, they're still pretty good quality fittings, and I'd try ordering Hayden fittings for other vehicles if I was doing another transmission cooler

This part will NOT fit a 1999 Jeep Grand Cherokee despite what Amazon indicates. I learned the hard way through a ton of research that the transmission cooler line adaptor/fitting is ONLY sold from the OEM with the radiator (so you have to purchase the entire radiator assembly to get it). My advice if you need this just this part is to visit a local junkyard and inquire if they have any 1999 - 2004 model Jeep Grand Cherokee's on hand that you can strip.

We're exactly what I needed to install the cooler on a 2000 keep Cherokee. These are a must for the inline Hayden cooler.
