My car overheated one day and I opened the radiator cap and there was no coolant at all. I filled it up with coolant/water and changed the radiator cap. Now I notice that reservoir cap (not the radiator cap)is sizzling out coolant once the car has been driving for a while. I have refilled my car three times with coolant ever since my car first overheated. A mechanical checked and he said there was no leak in the radiator or anything. Just today I drained, flushed, and filled my radiator with new coolant. I also added some leak sealer thing to it. What else should I do now?

Also, I gave my brother my car to get the AC fixed. I've noticed that there was a AC evaporator box in my trunk so I'm guessing he changed that. He replaced the fan for the AC too because he old one was not working. The problem is that I don't think the fan is working. How would I go to fix the wiring of the fan?

My car also leaks some kind of liquid INSIDE of the car when the AC is on. It's some kind of cold liquid that only leaks when I corner, mostly on the passenger side. The mechanical blew the little tube thingy (if you know what I'm talking about), but it's still happening. The AC is getting weaker too. It also squeals when the AC is on, only when I'm stepping on the gas though.

I car has a lot of problems, I know. It would be nice if you could help me reduce it.

 

I hate stopleak...
is the car still overheating? did you replace the thermostat? is there air in the cooling system (does the heater work?)

as far as your AC...thats water leaking from the evaporator case. sounds to me like something is put together incorrectly...

check your belt tension VS another cars belt tension...sounds to me like your belt is loose.
