Compatible with radiator on my 2000 Buick Lesabre 3.8
The Jiffy Clips holding transmission lines connected sometimes cannot be removed, even using the correct tool. I got three of the four clips on my lines off, but for the last I had to cut the pipe with a Dremel cutoff wheel and then remove this fitting from the radiator using a socket wrench. The factory fitting is extremely tight in the radiator and take a lot of force to unthread and remove from the radiator. However, with sufficient torque the fitting will come out without damaging the radiator. A LOT of torque to remove. These Dorman replacement fitting come with thread sealant already installed, and the thread right in easily. The standard GM transmission line metal pipes fit right in and seal properly. Note: It may not be obvious, but the Jiffy Clips are designed to not have to be removed. The removal tool fits around the pipe and spreads the clips without removing them. The pipe pulls out through the removal tool. To connect the pipe to the fitting, just push it in with the Jiffy Clip already in place. It will go in and lock.

2014 GMC 1500
I ended up using these to add a transmission cooler to my 2014 GMC Sierra 1500. I did need to use a rubber washer inside because I was using a brass connector.

Leaky O-Rings
Bad O-ring. I bought 2 of these for the transmission oil cooler on my 2001 Chevy Suburban. The fitting is the correct thread, and the thread sealant is nice. I lubed the o-rings with silicone grease, but the o-rings still leaked on both fittings. Like other's have said, not worth saving $2 over OEM. Plan on replacing the o-rings before installing if you want to save some hassle.

Make sure you clean the threads in the radiator
Worked out nice . Good value for the money

Fits original radiator only
So this gets a 5 star because it fits the original radiator. I couldn't use them however, because the secondhand car that needed them had another radiator in it but they would not fit it. I had no idea the radiator had been replaced so I couldn't use them. Not the vendors fault.

Some Dorman stuff is good, this not so much.
Doesn't work as well as the OEM version.
