coolant reservoir tank 2002 pontiac grand prix

I did however notice my electric fan is not working or was not today but usually that makes the engine overheat at a stop? my radiator is curved from the impact a year ago but there is very little fin damage and it does not have a leak. today it was blowing ice cold air and usually i have notice that if my heater blows cold air i can step on the brake and the deceleration moves water through the engine and the heater core so it gets warm while braking and cold during acceleration.

my question is the operation of said vehicle, so it is erratically over heating and blowing cold and hot hot air, some days it will over heat 1 time and others like today it wouldn't stop looking like a steam engine from old. Anyway so when i hit the embankment it bent the Radiator just like the Raccoon did when i first got my charger the first time, to say I dont have good luck is an understatement.

Yes I was the moron that ran it thru a T road and in to a small ditch, which the insurance company totaled and I bought it back. I will start with my Charger was wrecked about 1 yr ago.
