i got a 86 prelude. there's coolant leaking at the bottom of the left corner. right under the coolant reservior. i thought the bottle was broken. then i pull some coolant inside of it. but there's no leaking. so the next day i back home and park the car. the coolant leaking again. i wondering is the radiator hose or the water pump? it won't leak when you driving. and it only leak after you drive at least an hour on freeway. anyone help?
