engin overheating, bad gas milege, what elese!!! frig

ayte guys here is the lowdown,my clutch fan wasnt engaging, so i replaced it with another, so while unbolting the fan i had to loose the tension bolt for the powerstering pump, i thought it was turning, it snaped!! frig, so i checked it , the belt was still thight, it didn’t move an inch (rust was good this time), so it was still driveable, i guess? now when i drive the rad is dumping all the fluid into the resivor !!! :shock: and it’s overflowing, while i was comming home tonite the temp needle was high :shock: wtf, so i checked the rad hose the top hose was hot and with presure, the bottom was cold?? i could see the resivior was full and overflowing, , what could this be, is the water pump not working or it the rad cloged? ( could this eva happen) now that was problem 1
2 bad gas milege, i changed the fuel filter, no i didnt put the 300zx one, makes no sense, ther car is stock, the spark plugs are good, tips are good, i belive my o2sensor maybe toast, i think my engine is running rich, exhaust is poping when slowing down,
thats all for now, hope i dont encounter any more problems
have any of u guys experienced this yet? feedback will be greately appriciately , thanks

Check for air in the cooling system or you could have a bad thermostat, are you getting heat in the car?. If you think your o2 sensor is bad change it, it will cause your car to run rich (bad mileage) check for exhaust leaks for the poping.
