i could use some help.
73 mgb roadster, radiator recored at a supposedly reputable shop, new
thermostat, plastic fan, dealer add-on air conditioning, new sending unit,
reads same as old sending unit, second gage hooked up reads about the same;
system flushed by running water through it in the last few year or so,
antifreeze/water mixture fairly new, prob 60/40 to 50/50, new heater control
valve and radiator cap.
car runs hot, infrared says about 220 after typical 15 minute drive through
neighborhood; needle about 3/4 on an 80 degree day. have had trouble with
engine running hot for last several months as i've been working through
replacing/testing various items in cooling system.
try removing thermostat? what else to check? could there be a blockage
somewhere and how to tell/find?
