i need your opinion,
our everest has blown one of its coolant bypass hose coming from a trip from our farm. we stopped. then we saw water steaming out of the blown bypass hose... after being towed to our trusted mechanic shop, , upon replacing the bypass hose, we poured and filled the radiator to its full, but water is being spewed like a fountain on the radiator cap as the engine is running at idle..

upon searching and talking to other mechanics, their opinion is that the cylinder head gasket might have been compromised by the earlier incident of overheating... what i initially found out is that cylinder head leak symptoms include water rushing out from the radiator cap and bubbles coming out of the coolant reservoir...

any inputs will highly be appreciated
