I can't locate the heater hoses on my '02 Santa Fe. I do all the maint. on this machine, I've replaced the timing belt, plugs and wires (that was a bit of a pain) and done all the regular maint. required by the shop manual. The only hoses I can see enter the firewall are about mid engine compartment and can only be seen from underneath the beast. These hoses? are only about 1/2" diameter. I didn't trace them to the engine end as I thought they were too small for heater hoses, and they have no clamps like I'd expect to see. Am I missing somethin'? Are these the heater hoses? I feel like a dummy askin' this, but if someone can clue me in.. Thanks!
