Car getting very hot with coolant tank full

Umm the fan comes on when its like 3/4 hot. And I didnt check upper/lower rad hose. Someone told us to add water or coolant directly to the radiator so I think we will try that and I will check the upper/lower rad hose are getting hot as well. I will be back in a bit. And thanks for your quick response.

Its a 2004 and our manual suggested adding to radiator. Im not sure what temperature the fan came on before. But now we added water directly to the radiator. Drove it around the block a few times, the temp is now fine. However the coolant tank has gone down by about half. Does this mean its been absorbed into the radiator or do we have some sort of catastrophic leak while were driving? We are supposed to drive a couple hundred k tomorrow for xmas. Is this gonna be safe if we have lots of water in the car to keep adding to the tank if needed? Thanks for your help. You rock.

Were not too sure where the leak is coming from, we just noticed a puddle when we first pulled out before all this happened. I peeked at the undercarriage and cant see anything dripping at the moment, so im not sure how fast its leaking. We originally added coolant only to the coolant tank. Im guessing that didn't work at first because the radiator was still bone dry. Now that the radiator has coolant in it, it seems fine. Im just worried about driving long distance, and im assuming everything is closed on holidays. In case you couldnt tell this is our first car and we only bought it recently - i.E. We know shiza about cars. It seems like the last owner took very good care of it tho. And all fluids were topped up b4 we got it. Weve driven it about 5000 k since then with no problems. Last time we drove it we took it thru a high powered car wash, maybe this somehow caused the leak? Do you recommend we try and find an open mechanic tomorrow before our roadtrip? Or do you think it would be ok to drive it anyways, keeping constant eye on temperature, and keep filling with h2o if needed. Its not very cold here.

Hm well the car seems like it was taken really good care of the owner was very organized with his paperwork etc. Radiator caps in great shape. Theres a bit of orange-ish colored sludge on the inside of the coolant and radiator tanks. Thats probably not good. But again - I know nothing. We might just give the trip a shot anyways keeping a constant eye on the coolant level and the temperature and turn back if its bad. I really REALLY appreciate all your advice. Have a wonderful christmas if you celebrate.

Never heard of auto zone so I will look it up and give it a try if they are open. Thanks so much again. You probably saved our christmas with your advice. Good kharma to you :) merry xmas.
