Question:

water pump is bad?

my water pump is making this quot;chuckingsound, and i was wondering if bad water pump creates these sound? and also, do i need to replace the serpentine belt at the same time?

Answer:

I was trying to recreate the noise , being a Chuck I thought it would be easy but I can't :)). You should replace the belt for preventive maintenance and the radiator hose ( if applicable) as well...
my water pump dont make any noise. maybe its the belt.
pump is probably bad, and yes the timing belt needs to changed at the same time so you don't have to pay labor when the time comes to change it.
Make sure it's the water pump, but yes, they can make noise. It's never a bad idea to replace the belt when doing that kind of work. It's already off, so there is no labor, but if it's newer, it's not necessary.
In a water pump, you have what is called an impeller= the part that you can not see. The other side is the drive pulley in between them is a bearing. This is the source of your noise. Replacing the water pump will make the noise go away. As for the belt, If this is a timing belt driven pump, yes replace the belt. If this is a serpentine accessories belt, look at the condition, any cracks, fraying or obvious damage. use your own good judgement. Suggest you also replace the thermostat, this is a good preventative maintenance practise. Refill the cooling system with a 50/50 mix of water and coolant. Good Luck
