Bypass heater core on '94 UrS4

[Huw Powell]

On "most" vehicles (I'm not sure of the UrS4 setup), there will be two 
hoses fairly near each other on the firewall that look like they 
disappear into it.  The heater core is usually right there, with two 
nipples coming through the firewall, hoses clamped onto them.  That 
would be the ideal place, if you can get to it.
