Large O-ring does not work
Do not buy!!!Large O-rings do not work on 2012 5L F150!! It¡¯s to large and will not allow the tee to snap back in¡­

The fit was perfect
The product worked as advertised. Just a heads up when you change the seals replace all 3

Bought for someone else
I’m sorry that I’m unable to rate this product. I purchased it for someone else and don’t know the level of satisfaction they have.

It is what I ordered.
They fit fine but the o-ring that went on the thermostat housing. It leaks a little, that why I gave 4 stars. That is the only one that was not tight. Update: the little leak turned into a big leak and the o-ring for the reservoir tank started leak too. That why its a big old one star.

PERFECT EASY FIT
Thank you

Perfect fit and did the job
Replaced all orings within my F150 coolant system where there were the quick disconnects as I had a small leak. Worked great.

These o-rings may be all you have to replace if you have a coolant leak on your f-150
I purchased the entire plastic y connector, but found that there is nothing that can break on it. The leaks come from faulty o-rings. Dealer wanted $400 to replace the y connector, but all that needed to be replaced is the o-ring.

That these work and they do not sell them at the auto store.
This was the o-ring kit that goes to the radiator hose tee connector on my 2013 f150

worked, no more leaks
the old o rings I replaced were so worn out, surprised they lasted as long as they did.

Works great, cheaper than parts store
Good quality but hard to determine which O-ring goes where.

It came with 5 different size seals
I was able to use one of these seals for my F150. I installed it 11.10.2019. I have to drive it for a while to see if it fixed my radiator hose leak
UPDATE 11.12.19 Ive drove my truck 150 miles and there is no leak.

Stopped my T connector hose leak
I bought the whole kit just Incase I need others down the road but I only needed the o ring for the upper radiator hose on the non water pump side, which is typically where the 5.0s are leaking from. The o ring stopped my leak. I noticed a puddle under my truck when I left for work and found the leak. I topped it off and it had lost a little over half a gallon in the 4 days it took before I had the Oring.

Interior Dimension were wrong
I bought these to fix the dreaded 75K mile upper radiator hose leak ford is known for. On receipt of the package i made the change, and struggled to get the hose back on the fitting. It appeared to be secure, and i refilled the coolant system. All was good for a week of light neighborhood driving. However when hitting the highway , with stop and go traffic, the coolant system began to heat up. At this point the pressure appears to have caused the hose to come off the fitting. This spewed coolant all over my engine, causing the engine to overheat. I ended up having to be towed back home. And going to the Ford dealership. $10 later for a Ford OEM part and the situation was fixed. I then proceed to compare the inner diameter of the Ford OEM part, and these o-rings. These o-rings were smaller by a matter of millimeters. This prevented the hose from making a secure connection.

Did the job.
They worked great. Few months in after install and everything is working great. No leaks.

Fixed it easy
Fixed the coolant leak on the T pipe on my coyote 5.0 f150.

Fit
Fit like a glove. Stopped the leak

Perfect fit
Fix the problem

Shipping guarantee in 1 day didn’t happen
It was supposed to be one day shipping but it took 4 days. Truck has been down 3 extra days because of it.

Highly Recommend
Perfect fit, stopped all leaks.

right size
I used the coolant o-ring on a 2011 F150

Does not work
Did not fix the problem still have a leak

Came on time
Very good product

Fit perfectly on 2016 F150 5.0L XLT4x4
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 couldnt get the connection to lock in, so I went over to help. It turns out he didnt 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 wouldnt 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?

Great product
Print worked great on my 2012 f150

good price
works

Doesn’t fit, specs are off. DONT WASTE YOUR TIME!
If tried grease, soap, silicone lube, gun lube EVERYTHING! And cannot get the fitting to go back on. Slide right on if I put the old one back in!

Thanks guys for wasting hours of my time and patience.

Good quality o-rings
The full set of o-rings for the dreaded cold coolant leak was welcome and stopped my coolant leak when temps get below -20 C.

Fixes upper radiator hose leak – 2014 Mustang GT
This o-ring kit will repair the upper radiator hose leak at the plastic tee fitting on a 5.0 Mustang.

The o-ring on the radiator hose is located behind the white plastic ring inside of the hose quick disconnect. I didnt see it at first and thought this was the wrong o-ring kit.

Use a silicone-based lubricant to install the o-ring as well as grease up the fittings for re-installation.

Dorman products has a great YouTube video on the process.

Great cost and well made
Great fit good

2012 Ford Mustang GT
I bought this o-ring gasket seals just in case if I had to replace original for water pump, thermostat, and bottom pulleys replacement. Didnt end up using it, though looked exactly like original.

Satisfied
Fits perfectly came on time good purchase

Perfect.
Worked perfect. Saved having to buy all the hoses by just replacing the worn gaskets that caused me a slight pressure loss and ultimately warmer temps. A pick tool is handy to pull old ones and some non silicone OR dialectic grease to help the new ones slide on.

Y pipe leak? Try this.
Did the job. I sold the truck shortly thereafter so I cant speak to its 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.

Seals orings
Perfect

No more leak
Watched a youtube video showing how to stop my 2012 F-150 anti-freeze leak, this did the trick. Easy enough to do even with little mechanical abilities.

Great fit!!!
Great set of o-rings and a lot cheaper than the dealer!!!

didnt last
they did fit but after about 3 weeks had a leak again at the upper radiator hose fitting. took it apart and found that the new o-ring was getting flat just like the old one did after 8 years. now gonna have to try and find a set

Saved me a lots of money
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 couldnt find where the leak was coming from. He told me to bring it to Ford and see if the block was cracked. I wasnt 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 couldnt 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 cant detect a leak. Go figure!

does it fit
like

Impossible to fit
The rings are slightly smaller than the original ones I tried for about 1 hour to put one in to the T hose but it seems almost impossible to make them fit i tried heating them up to stretch them a little but it didnt help at all I guess I will have to look for another set

2013 F150 5.0 Coolant Leak Fixer
Just like all the other reviews say, if you have one of those Ford motors that have that dreaded coolant leak this might be a cheaper alternative than buying the fitting assembly.

Doesnt fit.
Only one of the Orings fit on my 2011 F150 XL 3.7L. Waste of money.

Not OME part
The O rings did work for 2 months but they failed after 2 months im going OME from now on.

It works
Worked perfect . Replaced orings on heater hose assembly and at the T connector on 2011 f150 5.0 .

They work
Replaced o rings on 2013 F-150. Took a lot of silicone spray to get them to lock on, but no more leak and have heat now!

Work great.
Great factory replacement.

F150 0 RING KIT
5 x O ring kit none fit.useless to me.

O-rings
Replaced o-rings on ford truck so far so good. Shipping service is good too.

Repaired leak
Repaired leak

Sealed right up
Fixed leaky hoses on 2011 f150. Great substitute for replacing complete hose disconnects

The o-ring set is easy to use
Used this o-ring set on my 2011 f-150

Super!
Good

Bag-O-o rings
Great price, that is why I bought this instead of the factory brand. Its an o ring. they seem to be good quality. I havent installed them yet, I just got them, but they seem to be good quality. My only gripe is when the package arrived, it was a small ziplock bag with 4 o rings and there wasnt a part number identifying each o ring. there was a picture in the description with the individual part numbers so I thought the package would show each o ring with a part number. Not a problem, thats why its not 5 stars.

Did not fit.
Save your money.

Stopped my leak
The answer to my coolant leak. 2014 f150 with 5.0 gas. Fairly easy fix, watch you tube. The lower radiator hose is a bugger to reattach.

Easily fixed the leaking coolant hose on the Ford F150
Works like a charm. I only needed one of the O-rings but bought these just in case.

Get the job done!!!
Works great on my 2014 F-150, no more leak on the upper radiator hose “Y” connect, did the coolant flush as well

Worked great on 2013 Eco Boost
Even though said it wouldnt 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. Well see how long it lasts, but so far so good.

Thank you..
Thank you..

Perfect!
I swapped my old o-ring with this one and havent had a leak since. Its been about two months so far
