What's involved in replacing the rear heater hose. I have a distinct
smell of antifreeze when the rear fan is on. Went feeling around for
the on off valve, grabbed a hose and got a shot of antifreeze on my
habd. Obviously a bad hose here.

Is it a quick and easy job (Ha) or should I plan for a day. How long is
the hose?  Any other hints?

TIA
