Mitsubishi Repair: Hose pipe busting again and again, blown head gasket, combustion gases


Question
Dear Sir, i am having Diahatsu Charade 1987 Achache Model, few days back water runs out in the radiator and sue to that the hose pipe connected to the radiator leaked, i have changed the hose pipe but from that day it is busting each hose pipe, why is it hapening? that is any problem in the engine? i have also checked the radiator there is no blockage. Kindly reply me as soon as possible.

Answer
I am understanding that after your radiator ran out of water, the radiator hose now either blows off or actually ruptures. I believe that as long as you are careful about bleeding the air out of the coolant system, then you likely have a blown head gasket/cracked cylinder head that is pressurizing the cooling system. That would explain the loss of fluid (into the combustion chamber and out the tailpipe) and the pressure in the system. There is a common easy test to check for combustion gases in the cooling system, I would recommend you have this done next.
