I just found a coolant leak on my FD and can't identify what this hose is to get a replacement. Could any of you name this hose or provide the part # to this hose so I can order one through mazda? On one of the pictures, you can see where the hose was punctured from that metal peice that holds the ss line down. This hose is located near the firewall, below the oil filter. Thanks!

 

Here's the hard line that it connects to. The hard line runs from the driver side to the passenger side firewall. The 2nd picture shows the hose on the end of the hardline on the passenger side. Thanks.

 

That's the hose going to your heater core. Call Malloy mazda and ask for Ray, give him a description of the location of the hose (or just tell him the rubber hose going to the heater core) he'll know.

 

Thanks a lot!! Is there anyway to drive the car for another day or two like this? Or is it too risky? There's a small needle sized puncture that leaks about a hamburger sized puddle after the car sits the whole day.

 

i wouldnt drive it... it blows you either overheat or your stranded.

 

Your coolant system is pressurized. It doesn't take much to turn a small leak into a gusher so I wouldn't recommend driving it until you fix it.
