Ooooh yeah, my van's front heater smells like maple syrup.  So what's
the problem?  I'm not losing any noticeable level of coolant and don't
see any leaks when I pull the plastic cover off the front blower.  I've
heard heater cores go out, as does a small plastic connector fitting of
some sort (cracks?).  I'm assuming I don't see any leaks because it's
all just evaporating before it can drip off the core.  How do I
troubleshoot this one?

 

Thanks,

Andrew
