i have a 97 gsr and i just put a new KOYO racing radiator in it. when i first start up my car car let it warm up and i drive around for a while the temp stays normal, then when i floor it the temp drops down really far ( stock temp gauge ). is this normal? this only happens when the car is just warmed up. now the main thing i wanted to question is, when i drive on the freeway for a while my temp goes up higher than normal. usualy its a little below the middle point, but at times it goes a little past the middle point. as soon as i turn the heat on the temp drops back to normal. then i slide the nob back to the blue area ( cool ) and the temp stays normal for a while then raises back up past the middle point again. i have my cooling fan hooked up to a manual switch and i have the fan on most of the time, but it doesnt seem to help. im sure the fan is blowing the correct way.
any responces will help.
thanks,
