well yesterday evening, my car started running hot and steaming on battery side on 2001 Honda Accord

It was steaming making abound steaming on the right side,I noticed where the top radiator hose is going to thermostat on the housing of the thermostat it had a bolt missing. I'm thinking it's the thermostat but not sure..after I put water in radiator again it was at norm temp then did it again.. Same thing when I stopes no water?please help thanks.

avoid driving your car if overheat,check the hoses where is leaking and seek help to diagnose if you're not sure.
i had the same problem and it was low coolant level. i first filled my radiator and then the extra coolant vessel upto the level. Now, it's been like a month and it's not having any more trouble. Good Luck!
