IS200 Cam belt and water pump
Yeah I think the dealer will not normally replace the tensioner. I guess they could say that people would complain if they always changed it, especially if it didn't look like it needed doing (i.e. it would cost more).
It can be useful to change both. Firstly, if the tensioner is worn at all, then it will cause increased wear on your new cam belt.
As for the water pump, in order to replace this, you have to take all the belts off to do this part. So unless you can be sure your water pump will last till the next cam belt change, it makes it cheaper to change it at the same time as the cam belt. Of course, that depends on exactly how long your water pump is likely to last, and that can be difficult to tell ! You can always have a look at it and see if you can see any leaks. Mine looked fine to me, but when it came off I saw it had been leaking from underneath.
Soz to re-start this thread but if the water pump has a leak is it a problem with the pump or just a worn out gasket? mines defo got a small leak but would rather just get the gasket done if that's all it'd need.
