[Picture is Dodgerunner's, not mine. It's from an 85GT, was posted in an old thread.]
The hose connects to the lower side of the thermostat housing, underneath the thermostat. It runs towards the firewall, then curves toward the center of the firewall and goes downward. I assume it leads to the heater core.
Does anybody know a part number for that hose from Goodyear, Gates, or anybody? I'm looking at hoses on NAPA and RockAuto but I'm not sure any of them match. They love to use terminology like "Pipe-1" and "Pipe-2" .. I have no idea what those numbers are supposed to refer to. I don't see anything that looks like it on Fiero Store. NAPA has a couple whose names sound promising, but they don't look right: NBH 11602 "Heater to Pipe-1" http://www.napaonline.com/C...=NBH11602_0117482194 NBH 10853 "Heater to Pipe-2" http://www.napaonline.com/C...=NBH10853_0117482190
Thanks for the suggestion. But from the picture that looks just like Gates 21515 which I've replaced before: http://www.rockauto.com/cat...moreinfo.php?pk=2766 Assuming that's the same hose (it looks like it) - that one goes from the water pump to a connection at the trunk wall. I have that hose in my notes from when I replaced it last January.
might be the dayco 88351 looks like the one in the pick saged a bit the 88351 is a cut to fit hose. looks like the 88351 in the pick it is cut at a bend just keep it in mind this is what the one with the red line under it looks like. but unsure. the sag fooled me at first i was thinking it was the firist one. take a look at the dayco 88351 style see if it will reach and if any thing cut to fit if you can. any ways wish you luck finding the hose.
I've had some requests to have this one made. I can have some made. Need a few samples. Can be junky and be slit to get off.
One more vote of interest here. I can't send you mine though, it's on a daily driver and it's still holding on, just looks to be in questionable condition at this point. Since the time of this thread I had forgotten about this hose, but I'm sure it's not getting any better. I haven't tried the Dayco 88351 or ACDelco 88907557 which were suggested, but I did see a thread where jetman found them listed as belonging to one of the variants of the heater core connections up front: http://www.fiero.nl/forum/A...110502-2-106613.html
