I need a new timing belt and I'm getting that done soon, but my mechanic says that water pumps are usually replaced along with the timing belt at the same time. Does it really need replaced?
not dont have to replace unless it was leaking it but it is off now and wouldnt cost anything in labor since hes taking it oof so get to what he need to fix but no it dont have to be replace til it leaks
no until it starts leaking.
yep replace at the same time better safe than sorry it'll cost more if it leaks later and you need to replace it
i have a nissan pickup and i changed the timing set at 88k miles and opted not to change the water pump. bad move, since my water pump was driven from my timing chain. the new timing set put more stress on my water pump than the old slacked one did, and about 6000 miles later the seal on the inner water pump shaft started leaking and filled my oil with water. it took about a week for the mechanic to diagnose the problem and cost me 550 dollars in labor and parts. should've changed the water pump when i changed the timing set. could've saved 300 dollars in the long run. now if you have a belt driven water pump, like that in a chevy truck then it should be fine.
What kind of car? That info would help. Well, usually on most import cars and some domestic, the timing belt runs the water pump. If this is the case, then yes i would be replacing the water pump with the timing belt because if you don't then when the pump leaks you'll end up paying almost the same money again for water pump job.
