How to protect AC line from header and control arm?
My '94 Caprice wagon has ceramic coated headers. The AC hose runs very close to the headers and the edge of the control arm.
Several years back, the AC hose blew because it rubbed up against the control arm (the edge of it which moves up and down) and eventually wore through. My mechanic replaced it with some generic Chinese hose. That one failed due to heat from the header. The second Chinese hose got wrapped with heat shield stuff, but it also failed due to heat. Then I bought an AC Delco hose and had him install that with the heat shield wrap, and that one lasted.. until last weekend. (I'm not sure what kind of wrap it was--does it look like just regular header wrap? I'm done going to that mechanic so I can't ask him what he used.)
I haven't dug in to be totally sure, but I'm pretty confident that it rubbed up against the control arm again and wore a hole in it. The heat shield wrap seems to be sufficient for heat protection, but I'm looking for a definitive solution that won't rub through easily if the hose ends up touching the control arm as well. What do you guys recommend?
