Because if dies on you after you have replaced the timing belt it will cost as much as replace the timing belt. If you do not know, in order to remove the water pump you need to remove the timing belt it's about $300-600 depending where you live. Do you really want to pay such money twice?
Yes, you should.
If the timing belt drives the water pump you should replace the belt at the same time as the pump.
4cyl. engine does not have timing belt,6cyl timing belt and water pump should be replaced every 100k miles
You should only have to remove the serpinine belt to change the water pump. The timing belt is inside the plastic covers. The serpentine belt is visible to you.
The water pump should be driven by the timing belt, yes. If you change the water pump, you might wanna change the timing belt and tensioner while you're in there.
The timing belt cover should be right behind the water pump .. So remove the water pump then remove the timing belt cover then remove the timing belt then do all them steps backwards
when should i change the timing belt on a mercury villager
I have a 2008 Subara Impreza. When should i change the timing belt? Do i also need to change the cogs, tension bars and water pump??
The water pump is loacted behind the timing belt. To change the water pump you should also do the timing belt.
behind the timing cover you should change the timing belt when you change water pump.
You do not have to, but if the water pump is timing belt driven it is highly recommended.
You do not have to change the timing belt to replace the water pump. You do have to remove the timing belt cover to be able to access the bolts that hold the water pump on.
