Block drain plug location?
no block drain plug,you drain from radiator,is a plastic twist plug on bottom.
Ok. I drained radiator, changed upper hose, and cleaned resevoir bottle. then started the lumina and couldn't get hot air at operating temp. Did I do some thing wrong?
you should try using a low phosphorus coolant and check your thermostat
replace the thermostat,if that dont fix it your heater control may be bad.
also you need to blead the air out of the cooling system,should be a bleader valve close to thermostat housing,if u cant find it ,remove the cap off plastic container where u put antifreze in crank let it idle with defrost on fan on high,just let it idle it will get rid of the air in the system,it will burp out collent just let it run until this stops,may take a hour,refill put cap back on,air is out of it.
