Have Ford Questions? Ask a Mechanic for Answers ASAP
Tim, this is where I need help. Can you tell me which hoses are the heater hoses? Can you find a drawing on the firewall area that have these two hoses?
Tim, I'm back. You have the following, what I do next?
Oh, the location of these hose are far below the plan of the firewall. I will give it a try
Let you know when I have some thing.
Thanks, XXXXX XXXXX you later.
Great expert Tim, we now have better heat (not very hot still, though) and your advice helped me to improve the heater.
(since there is no way I can reach to those hose clamps, I use an alternative by squeezed shut the bypass hose with a hose clamp then flush the right hose (from engine to fire wall) with high pressure water. In the process, I saw a huge amount yellow water got flushed out. I let it floush untgil the water turnedd back to clear again. Initially, I though this is it, but unfortunately, the heat still not increase. My last try was to clamp the bypass hose for good and in this way, when the car is driven, the heat is somewhat better.)
Tim, can you be more detaail on why you think the heating core is bad?
Thanks. I will add some radiator flush/cleaner from AutoZone. May also add some CLR.
It costs $400+ in labour to replace the part (had to remove dash board) this is not a small expense.
My problem is unable to access these two hoses. I can see them, but the space is not enough for me to get the tool to it.
Also, what chemical you are referring to? I do not know the chemical flush used by the PROs.
Thanks Tim, I will try and see if I can make it.
Merry X'mas and Happy new years to you.
