----pre sometimes ung pressure ng radiator anjan lng yan.it happens lng na theres a problem with the coolant that you use (if meron) kasi if you dont know water alone as coolant creates electrolysis is water that can cause mga d inaasahang bagay.. check your coolant, coolant must be -35 to make sure that it is good and will not affect your car.
