There are various things which could cause a cracked radiator. You should try to consult a professional on the matter.
If the radiator is cracked then the vehicle has ran dry on coolant. This would cause the radiator to crack if there wasn't any coolant.
The radiator hoses could be cracked, look where they are clamped to the rad. and engine. The radiator itself could be rusted or cracked somewhere.
Leaking and overheating from lack of pressure.
Best bet is to replace the radiator.
A cracked radiator would leak the fluid out, leaving no coolant for your engine which would cause your engine to overheat and be destroyed pretty quickly. So the answer is NO.
