2011 5.0L Coolant Leak
#11
I just finished replacing my hose and it still leaks...
Has anyone actually seen a crack in the reservoir tank or connector? I am afraid that there is another problem that could be pressurizing the coolant and causing the oring in the quick connector to fail. I will install a new tank this week and recheck.

not covered under extended warranty
Ford let me know this was not covered under the extended warranty.
Even if it was there is a large up front payment so even if a part is covered under the extended warranty the min. charge may be more than the part. That was the case in my turn signal switch as well.

I'm pretty sure mine was leaking in the fitting it's self not the actual reservoir. The RVT did hold up well for a month or so and now I'm back to the same problem. Perhaps I didn't put enough on to make a good seal. Anyways it's back to pulling her apart. Good ol' fords

I noticed that you used different RTV than I did when I fixed mine. I used Permatex red hi-temp. Not sure if that's the difference or not, though; because I replaced the tank, hose, and then added the RTV for extra insurance.

Ya the stuff I used is oil resistant and flexible. Got it from a buddy that works on heavy equipment. Said it should work better because it's industrial grade stuff. Apparently not the right application.

My 2011 F150, 5.0 has always had a slight whiff of antifreeze since new , after 39,000
miles a small puddle appeared under the power steering control box, after reading the posts , I found the lower pressure hose on the expasion tank wet, I removed cleaned and inspected the tank and hose(no cracks), reinstalled with a fuel sealant called Titeseal, (no success) I ordered a replacement hose and will retry, short of using an epoxy two part fuel tank sealant to permently attach the hose to the tank, Bill

Thanks for your advise , The new hose silicone seal appears to be coated with silicone dielectric grease, I'll probably buy a new tank to resolve this before it gets cold and have to deal with coolant fluid leaks , the stuff seems to corrode everthing it touches, Bill
