i swapped a b16 into my ek, i followed the way my cooling system runs from my sohc(hoses). when i start my car, it overheats, when i mean over heat, about 3 minutes after i start it up, it starts boiling. the lower radiator hose isnt even hot, i swapped out my thermostat to a new one. still doing the same thing, still, the lower radior hose stays cold. i dont think i ran my hoses right. there is a "U" hose in the back of the motor that goes from the im to the block, should it go on the outside or the inner one? any pics of the engine bay from the passenger side will help a lot. thanks.
