pressure check to make sure it is a freeze plug auto parts rent pressure gauge/pump. if so they can be replaced how hard depends on where they are. some of these engines if anti freeze was mixed other than 50/50 head bolts pull out from block and engine blows head gasket. then block has to be heli coiled to fix.
