It depends on your experience and a car you have. Some cars have water pump very easy replaceable. Other cars (most of them) have water pump behind the timing belt. It should take you from 2 hours up 6-7 hours.
how much labor time does it take to change the water pump on an 07 impala
2 hours max....
It's recommended to change the water pump at the time when you replace the timing belt.
the water pump is turned by the timing belt and it is recommended that you change the belt at the same time as the water pump
If the water pump is driven by the cam belt then change the water pump at the same time.
No, but it can be recommended on a system where the timing belt runs the water pump.
A water pump has a "weep" hole. When the seals start to wear out the water pump will still start to leak from this hole. When this happens it is time to change the water pump.
If the timing belt drives the water pump you should replace the belt at the same time as the pump.
If the pulley wobbles or coolant is leaking out, it's time to change the pump. Or, if you have a vehicle with a timing belt and it's time to change the timing belt, you may actually save money in the long run if you change the pump at the same time since most of the labor is already done with the belt change.
what year firebird?
in with the timing belt change them at the same time
the water pump is under the timing cover, if you replace the water pump, it is also a good time to change out the timing belt... Honda recomends changing water pumps when you change the timing belt...
