my heating system decided to not blow out hot air on the day it is
into the single digits...the only thing i can think of that i did is
last week i filled up my antifreeze and after about 1 quart realized
that i did not dilute it with 50/50 water to antifreeze, so is it
possible that too much concentrated coolant is doing this...my engine
heat gauge stays way below cold and does not even creep up after
driving for an hour
