Do not buy if you are trying to replace o-ring in hose coming from the overflow reservoir. My truck is a 2018 f-150 and the smallest o-ring was too big.

I keep a set or two of these on hand. Never know when that silly hose design will start leaking.

My water pump failed on my truck at 70K miles, so I opted to change all the O-Rings on the quick connect radiator hose fittings. What a dumb design, but here we are. Mine leaked at the Y-Pipe where they upper hose connects but only for a few miles and early on in my purchase. I picked it up in 2019 with 31K miles on it, but I figured I was deep into it already, so why not do this job, too.This kit contains the upper and lower radiator hose O-Rings, which are the same size and the largest two in the pack. The upper hose is the easiest, add it's the most accessible. The lower hose is a bit harder, but it's much easier to access if you remove the air cleaner and degas overflow bottle. The next largest O-Ring is for the Y-Pipe that connects to the thermostat. Ford wants you to buy the entire pipe when all you have to do is remove it to refresh it. Granted, it's a bit tight and hard to get those constant tension clamps off, but it's worth it. The smallest O-Ring is for the degas overflow bottle, and is super easy to access.In all instances, pick out the retaining clip with, of all things a pick and/or a screwdriver and needle nose pliers. There are videos that show how to do this. The O-Ring is located beyond the tapered Teflon looking thing at the end of the fitting. Use the pick to get under it and temove. Add a light coating of silicone grease or coolant to the new O-Ring and squeeze in half. Insert the rounded end beyond the Teflon thing and into its channel. Use your thumb to hold that end in place as you work the rest of the O-Ring into the channel with your other thumb. In all cases, make sure you hear the audible click upon reinserting the hose back in place and make sure that retaining clip is in place. Clean off coolant gunk on any male fitting with green Scotch Brite.

I needed one of the orings and it fit. Cheaper then the Ford dealership. Stopped the leak. 2015 F150 Lariat 5.0 Coyote motor.

I was able to replace the upper and lower, different sizes, O-Rings on the "T" water pump connector. Both were a perfect fit like the Factory supplied parts. The problem of the cold temperature leak is fixed.

Even though Amazon said it wouldn't fit in my 2013 F150 Eco Boost, the small one for the reservoir connector worked great. The old O-Ring was flattened out, and this sealed it up perfectly. We'll see how long it lasts, but so far so good.

Works great on my 2014 F-150, no more leak on the upper radiator hose "Y" connect, did the coolant flush as well

Did the job. I sold the truck shortly thereafter so I can't speak to it's long term effectiveness but the leak stopped & held pressure once replaced. Probably a good place to start on the Ford Y Pipe, as opposed to replacing the entire y pipe.

Like the title says, it fit and sealed perfectly on my truck. For reference, I told a friend about my experience with this product because he was experiencing a similar leak on his 2017 Mustang 5.0L. He bought the kit and called me to say he couldn't get the connection to lock in, so I went over to help. It turns out he didn't remove the old o-ring from the housing, instead he slid the new o-ring onto the spigot and tried to force the quick-connect over it. He was right, in that configuration it wouldn't go together. It took us 5 minutes to pull the old o-ring, install the new old and get the car buttoned up. No leaks for him either and once it was installed correctly, it snapped together without issue. This makes me wonder how many of the negative reviewers, who indicate poor fit are just not installing it incorrectly. Maybe an instruction sheet would help?

I had an anti-freeze leak and brought it to my mechanic to find the source. I usually do all my mechanical work myself but couldn't find where the leak was coming from. He told me to bring it to Ford and see if the block was cracked. I wasn't prepared to leave my truck at the dealership because I need my truck for work. Anyway, one morning I saw a HUGE puddle of anti-freeze in my driveway. More then I ever seen before. I popped the hood and found a puddle of fluid sitting on part of the frame and the plastic shield. I thought for sure it was my water pump but couldn't confirm. I took a rag and cleaned as much as possible to see where the leak was coming from. I then ran my hand near the thermostat housing and there was liquid on my hand. I then took my iPhone and recorded a video and noticed that their was a drip around the thermostat housing. I then cleaned the housing dry and waited a few minutes. Ran my hand and sure enough, it was wet. I cleaned it again and touched the bolts seeing that the fluid was dripping from there and they were dry to the touch. I then ran my hand on the hoses at the TEE and sure enough, there was the leak. I ordered the O-Ring kit, arrived the next day and VOILA, no more leak! One thing that upsets me the most is that there are hundreds of senors on new cars but they can't detect a leak. Go figure!

Good quality but hard to determine which O-ring goes where.
