What a waste

Question : My Suzuki ERV 1.3 litre (2002) has clocked 83,000km, which means it's time to have the timing belt changed. I was informed by Suzuki that when I change the timing belt, I should also change the water pump as well because if the water pump needs to be replaced (after I have changed the timing belt), I will have to replace the timing belt again. But replacing the water pump, which is still in good working condition, sounds wasteful. Also, is it true that cars which use timing chains instead of timing belts, do not need to have their chains replaced?

Answer :

1. The mechanic may be correct in a way because he may have found out in practice that the water pump usually fails not long after the timing belt is replaced and therefore suggests you replace it at the same time. However, you do not have to replace it as the labour to replace the pump at a later date is not that high and it it is not making any noise and operating perfectly well, I see no reason why you should throw away some- thing that is still good.

2. Timing chains, being made of steel, tend to last for a very long time and are seldom replaced, at least during the time the car is with the first owner.
