For what its worth I already tried a search and looked in my chilton manuel but couldn't find the part number for the coolant hose running through the fire wall to the heater core. Does anyone have the part number for this hose or a suggestion as far as a replacement hose? I've only owned the car for < month and the hose broke on my way to school directly after the nipple going into the block and almost fell apart in my hands while trying to fix it; so for now I just cut off the ruptured portion, refilled the fluid to limp it home and have it sitting.
Thanks in advance to anyone who can help.

 

Ah, the infamous left-side heater hose claims another victim...Look it up on the Mazdatrix website, it's like $28, when you install the new one, cover the area under the oil filter with some black RTV, that'll keep the oil off of it for a while...

 

Mazdatrix it is. Thank you, thank you very much.

 

argh that one got me, too!
