I am taking my car in for a timing bell replacement. My car is a honda accord 2001 6 cycl. The mileage is 80K still way under the manufacturer recommendation. I am thinking of replacing the oil pump and water pump. I am thinking that since the engine is already opened might as well get this done. I don't know if this is necessary. Are these items even closed to the timing belt area? Does anyone have any recommendation when this should be done ?
You should replace your water pump with the timing belt service. This is why: The belt from your timing belt turns your water pump if your water pump were to go bad and let's say seize up it could cause your timing belt also to fail. The other thing is that the labor to open everything back up would be a very high cost just to replace the water pump. It makes more sense financially to pay for the replacement of the water pump (30-60 dollars) than to go back in 20k miles into your new timing belt and have to take everything apart again to replace the water pump. The oil pump should not need replacing unless you have a vehicle with 300-400k miles and you are doing a rebuil engine. Use a quality synthetic oil and a quality oil filter and the oil pump should last for the life of the car.
Oil pump should be replace when engine is getting rebuild Oil pump at 80k = no Water pump with timing belt is preventive maintnanace thing. To replace water pump require removing timing belt. Most people just go ahead and pay extra to have water pump replace at same time with timing belt. Shop should just charge your cost of parts for water pump and coolant. water pump with timing belt is your call.
You should not replace them if they are still working. These items can work for ever or stop working as soon as they are installed.
