It looks like the heater core in my 99 V-70 was leaking more and for longer than I thought. It seems the carpet underlayment (the dense foam with the gray plastic coating) has done a very good job of soaking up a bunch of coolant.

It also looks to me that it is not very practical to completely remove the underlayment for rinsing and drying. It is one piece from side to side, and appears that it was installed rather early in the assembly process. For example, before the steering column, rack, and heater blower were installed.

The only practical thing I can think of is to cut it as high above floor grade as I can, clean it, dry it, and glue it back down again.

Anybody have a better idea? Anybody know the trick to removing the rubber foot rest on the driver’s side?

Thanks,
Charley
