Question: Are the heater hoses to the heater core attached to the cylinder head easily accessible from the top? Are they below or near the battery box?
My 2006 Ford Focus heater is blowing cold. It has been progressively worse (not so hot air) over the last few years, and now it seems like the heater core is blocked. It was barely warm enough last year in the Boston winter, so I knew this was going to happen. (I just thought I would be able to get one more year out of it, before I sell it next year.)
I located the heater core. The two hoses connected to the heater core are visible from the top. But they seem to be almost impossible to reach, either from the top or bottom. So, I am thinking it might be easier to reach the other ends of the heater hoses–where they are connected to the cylinder head. I am thinking they are attached at the rear of the cylinder head, where there is the battery and the air intake box. Am I correct? Are they relatively easy to access?
