AFTER you have had it running and driven to reach maximum temperature, do you get good heat(HOT)? IF 'yes', I recommend verifying ACTUAL engine temp. , with an infra-red thermometer. I suspect a faulty sending unit, or improper parts installation. Engine/radiator cooling fans NEVER come on , unless you turn on A/C (or defrost), correct?
Fans dont run radiator has cardboard in front of radiator except 4" square. If head gasket was out should over heat in summer and it doesnt its been cold in winter for last 3 yrs. Time to trade it thanks. If coolant was blocked then it should over heat
