Coolant under drivers side mat?
 

Exactly what the title says. Bought a used '99 Volvo S80 T6 and there is coolant under the drivers side mat??? any ideas ??? any ideas on how to clean it up???

Leaking heater core.

anybody know where I can get the heater core O-rings in Canada?????

those can be ordered online at many places. make sure you pull out heater core to inspect for any cracks. it may be the heater core and not just the rings.
