vehicle overheated, acted like low on coolant but was not. Changed coolant, thermostat, and flushed system. Overheated again. Replaced radiator and waterpump. Noticed water in the oil when changing oil and filter. I suspect intake or head gasket. This would never have been a problem on an older vehicle with standard antifreeze and gaskets.
