Dorman 626-541 Engine Heater Hose Assembly Compatible with Select Ford/Lincoln Models (OE FIX)

I was having all of the same problems that I read about in the comments, and I hope this review saves someone some frustration.Watch a YouTube video before you startThermostat Side: When you remove the old T, check the thermostat side and make sure that the old O-ring and plastic O-ring retention fitting ring did not get stuck on the thermostat housing. Nothing should be left behind (you should see nothing but silver aluminum on the thermostat side). When I installed it the first time I thought that it was seated (it even made the click sound like it was locked in) correctly but when I went to pull on the T to verify I was able to pull it off, after inspecting everything I found that the O-ring and the plastic O-ring retainer was left on the thermostat.Upper Radiator Hose: The kit does not come with the replacement O-ring, you will 100% need to replace this O-ring, and is most likely the reason you are leaking coolant.Fitment: It's going to be a tight fit and when you are replacing with a plastic OEM T coolant can work as a lubricant. This however is an aluminum T and using some silicon (I used electrical connector silicon) as lubricant is going to be your best friend. Pull that hose off the T and lube it up and put the T back on the hose, you will need it to have some movement when installing. Once you get it on and connected to the block and thermostat the hose may not be seated correctly, if you lubed everything up really well you will be able to rotate the hose until it seats perfectly around the fitting.

Fit great on my 2014 Mustang GT coyote engine with no problems and no leaks. Better than from factory

Looks like a good replacement coolant hose wye for the 2013 F-150. The old ones were all plastic. This one has cast metal on the side that makes up to the thermostat housing. It may help the o-ring to be more stable. Order a new o-ring for the existing upper radiator coolant hose. The old one will be flat and hard.

Installed it on my Ford 2013 F150 4x4 last year. Was an easy install. No leaks. Great quality!

As other reviewers have said, the hose may be a little long and I did have to trim it which was a little frustrating so I docked it a star. In hindsight I should’ve gotten an OEM part. It did hold up to a 2800 mile road trip through extreme Arizona heat among other challenges.

This was a heavier duty match for my 2012 f150. This worked excellent for my radiator leak.

Like others said I have had great results with Dorman but this does not fit tight at all leaks. Went to replace orings and bought this because it was metal not plastic. Leaks. Going to get motor craft original now. And hose is to long. Hooked to brand new motorcraft hoses. Loose fitting compared to stock.

Perfect replacement, o rings previously leaking. Replaced the whole thing. Good fit
