Gary,
Many high line (cold climate) cars have intergral aux coolant pumps that
help the climate control steady the heater output due to RPM variation.
Low line cars do not. So most cars lines in Northern Europe and possible
Canada offer an add-on pump for low engine speed compensation. Mine was
for a BMW 316i and fits into the engine output hose to both heater
cores. My heater/defroster output will "burn" your fingers at idle. At
higher speeds the engine coolant pump is adequate and I switch it off.
Regards, JP
