'95 Kia Sportage overheating

My neighbor has a 1995 Kia Sportage that is overheating…he said the last time it got hot a stream of water shot up onto his windshield. He has been unable to find a leaky hose, etc. Could this be the head gasket?

A simple pressure shold be able to find the source of the leak. Good news probably not a head gasket.
