Assalamoalaikum, I have margalla 92 model. 3 days ago i noticed that heat was coming out of hood i parked the car and opened it, water was pumping out from the coolant bottle at that time i observe that bottle along with the radiator was almost empty but i filled up both and things gets easy.....but today again i heard an annoying voice, at first i thought it is from wheels but upon reaching my destination i pulled up the bonnet and remove the cap from radiator, water was boiling with some bubbles and coolant bottle was also empty(filled up 3 days ago) i used water to normalize the heat from radiator and filled it again..and yes my radiator also requires service due to rust in the water...what do you think servicing the radiator will resolve the issue or whether, its a gasket problem ..if its a gasket problem please tell me the cost of replacing it..SHUKRiYA
