In my 90 integra i have a new dual core 92-95 civic radiator,new thermostat,nearly new headgasket and i took my waterpump off and inspected it to see if it was fucked but it spun freely and i see no coolant around the weep holes.and it still overheats.

 

ok..i change my thermostat yesterday which i found out it was bad so i change it then i drove it a few time around my block real hard which it didnt over heat at all so i thought i fix the problem but today while i was driving to the store it started overheating again and i wasnt even boosting, i was driving for about 30 min. ok now im thinking of adding the oil additive-restore ---- and mayb check my water pump , n also i change my oil before i put a new thermostat and i didnt see no coolant in it, so does this mean its not the head gasket?
