allright..my car would overheat for some fucked up reason so i just took out my thermostat. now the temp guage is nice and low when i check it...the thing is at night its SUCKS..the **** is cold...my question is what kind of thermostat do i need for a D15B engine..i put a 92-95 civic thermostat in but it still overheats..maybe its not even my thermostat **** i dont even know but the thing is when i check my lower hose of my radiator its empty (no liquid inside it at all (when i have thermostat in)) but when i take my thermostat out it flows. IT could not be my thermostat so what do all of u think it is. basicly i would like to know what kind of thermostat i need for my engine..and if its not the thermostat thats messing up then what is?? thank you for your input.(when i drive the temp guage just sometimes jumps way up to the highest it goes and then just drops down in like a sec. dont know what it might be..maybe bad sensor even, i dont know but please help me out.)
