Coolant leak in 12v

[Kneale Brownson]

Not familiar with the 12v set-up, but is the heater core located similarly 
to on the Type 44, in the space between the top of the firewall and the 
bottom of the windshield?    If so, it's possible (given the coolant 
spotted behind the US passenger wheel) there's a leak in the connection to 
the heater core, outside the box holding the core but inside the well 
behind the firewall, and that the fluid ends up going to a drain in the 
bottom of that well.
