My guess is that you have a combustion leak from a blown head gasket, cracked head or cracked block. A combustion leak will result in excessive cooling system pressure, which could in turn lead to a cracked radiator. A professional will be able to validate this theory by checking for hydrocarbons in the cooling system. The team at YourMechanic would be happy to assist you in the diagnosis and repair of your cooling system problem.
