- Coolant is leaking from the coolant reservoir where the heater hose plugs in it. We've got a 2011 F-150 with the 3.5 liter EcoBoost engine. Should be a simple job if everything goes smooth.

UPDATE: Leak has remained fixed since replacing the coolant reservoir.
Even replacing the coolant tank and hose it'll still leak after a couple of weeks, use part # B-71750 hose from AutoZone and a 1 inch to 3/4 inch brass barb coupling from Home Depot, cut the hose in a 90°, spray some WD40 on the coolant tank and hose, the hose will slip easily over the entire nipple, cut the quick disconnect end and join both hose with the brass coupling, use 2 clamps on the coolant tank nipple and 2 clamps on the brass coupling, this will fix it permanently I did it to my 2014 F-150 last month and it hasn't leaked since.
That’s what they should have done at the factory. I’m lucky enough to still be leak free but it’s just a matter of time. Manufactures always designing for easy assembly knowing full well it’s going to fail.
Good s***, Mike. I’ll be doing this exact job here soon.
Good luck! It’s an easy job. I hope you keep better track of your bolts than I did.
Hey Justin, If you want to reduce costs and avoid replacing the entire reservoir + filter housing check out this video --> th-cam.com/video/OOtr6761Hs8/w-d-xo.html
It's what I'm doing with my 2014 5.0 once the parts arrive at my door.
whats the part number for the large hose with the connector?
did you drain the radiator to remove the fluid from the overflow tank?
Did you try replacing the o-ring in the connection first before replacing the tank?
Late reply here but, yes I did. I was hoping it would be an easy fix like that but it kept on dripping sadly.
@carsbymike5154 I would say late reply!🤣 All good though. I did the same thing. Replaced o-ring first and that didn't work, so I replaced the whole tank and air box and that fixed my problem.
What is the part number for the old ring?
O ring part number
@oliverdunn1350 I think it depends on if you have the 3.5 Ecoboost or the 5.0 V8. Also, it depends on what hose is leaking. If you do a search on Google for the o-ring, you will get some really good results as far as o-ring kits to replace all the o-rings for your hoses and expansion tank. I don't think I used an OEM one. I just bought a bunch of random o-rings and matched them up to the one. I think it was the closest. I do know if you buy the o-ring from the dealership and it's stupid expensive for a an o-ring. I think it's between $10-$15. Hell for that you can buy a whole assortment of o-rings, which will work. If I'm not mistaken, my o-rings is a Tuff Ring. I found their o-rings to be thicker. Once I got it in the hose and the hose put back on my new expansion tank, she sealed right up with no problems.
Is that a factory part ?
The hose was a factory part but the coolant reservoir was a Doorman replacement. Besides price, availability was a big factor in going with the Doorman reservoir. If I remember right, the Ford part would have taken several weeks to get and I really didn’t want to wait that long.
What did they charge you for a new tank? OEM right?
The new tank was a Dorman replacement part from Rock Auto. Part number 603275. Cost $168 to the door. Not exactly cheap but Ford has OEM part listed for $269 right now. parts.ford.com/shop/SearchDisplay?searchTerm=8A080&storeId=1405&catalogId=251&langId=-1&searchType=keyword
I imagine there are some replacement sources that could be cheaper. I tend to use Rock Auto for the availability they usually have.
I’m going to the junkyard
