2003 Mazda MPV anti freeze smell

Hi there,

Are you loosing coolant? Have the cooling system pressure tested with the heater on hot, this will show up any leaks in the system, if the heater core is leaking, look for any coolant around the low air out lets, get down and try to inspect up the vents with a torch, or even a stick with a bit or cotton attached but don't poke to hard at anything, just wipe around the lower vent tubes that you can reach looking for moisture. :D
