When my wife was driving on freeway, the alternator belt broke and battery sign showed up. She also told that the temperature gauze showed high. Luckily she reached home with the battery fully charged. When I checked under hood, there was coolant spill surrounding water pump . I could not figure out where the coolant came from. Overnight parking did not show any further leakage of coolant. is there a need to change the water pump also.
Depends. On older vehicles they used multiple drive belts for the different components (my '88 Caprice had 3 belts), but most newer vehicles only use 1 belt called a serpentine belt which drives multiple components (my '00 Dodge Ram 1500) If you lose your serpentine belt it will set the battery light as the alternator is not outputting the correct system voltage, and since the same belt drives the water pump then yes the car will overheat. It's dangerous to keep driving like that, most newer cars have aluminum heads which will warp when they get tooooo hot = expensive repair
For one thing. Once the belt breaks your battery light will come on because the alternator can't charge the battery anymore and also your car will overheat if you have a serpentine belt because once the belt is broke nothing will move anymore including your water pump. Your leak probably came from the overflow tank which is normal when a car overheats. You don't seem to know much about cars so I assume that you really don't know where the water pump is. Change the belt and than hope to god that she didn't run the car to long while it was hot to crack the head gasket . oh and make sure you add enough coolant back to the cooling system before you start the car again
