I started noticing I smell antifreeze so humm, I think I'll look. Well the little thing on the water inlet housing where you add coolant is leaking. It apears to come up higher than the gasket. Is that thing totally replaceable, or is it the cap. Anyone know? Or have a part number handy for the whole thing. I went to the mazda dealer and they were like we dont know give us a part number

 

my car has the EXACT same problem. i have been told that it is the thermostat as well as the plastic part.. im going to the mazdadealer this weekend to get the parts.. i will let you know how it all works out for me.. looks like about a 30 min job if i dont have to drain the coolant.. (ick)
