Could it be anything other than blown head gasket , cylinder block or head crack
I have a 2004 Dodge Durango Hemi SLT with 185+ thousand miles. My car had been running hot and my dad told me to add water to the radiator the water I added wasn't cold and I let the engine cool down before I added the water. It ran well after but when I left work tonight I went to the gas station to check the radiator reservoir and when I turned the radiator cap water overflowed (I did bot fully removed radiator cap) The car wasn't hot and the car had been driven for less than a mile. There is no smoke coming from the exhaust pipe nor is their any water in the oil. I have come to term with the fact that the car may be done but I would like to know if there could be another problem that's not as severe.
Doesn't sound that severe. If you have a small leak, your coolant level will go down and the engine will overheat more quickly. The overflow bottle is pressurized, never remove when warm or hot. Best to find the leak and repair. You can pressure test the system to detemine where the breach is.
If you are concerned about a blown head gasket, have it block checked, that will tell you if you have a problem. But from what you have stated, do what Tom suggested, it sounds like you have a small leak in the cooling system and if it is not corrected then that is when the real trouble begins.
