Can a blown cylinder head gasket cause a radiator hose to blow off?

Yes, a blown cylinder head gasket can lead to excessive pressure in the cooling system, which may cause a radiator hose to blow off. When the gasket fails, it can allow combustion gases to enter the cooling system, increasing pressure beyond what the hoses can handle. Additionally, this can lead to overheating, further weakening the hoses and increasing the risk of disconnection. Regular maintenance and prompt repairs can help prevent such issues.
