Started with no heat from heater then overheated with no water in radiator and oil was real low. Fluids were replaced but still no heater. I question if there is water in radiator at all. Now engine runs terrible does not shut off, but feels like it has a bad spark plug or two. Is it in safety mode? Is another way to get water in radiator besides the overflow container?

Hello,

You can remove the upper radiator hose and pour the water in when the engine is off but you should not need to do that. To me it sounds like you have a blown head gasket which causes the heater not to work and the engine to over heat. Here is a guide please follow it and report back:

Please let us know what happens.

Cheers, Ken
