Worth replacing timing belt while changing water pump?

[Brabbit]

My truck has 170k miles and my water pump is leaking. I've read a lot of conflicting advice about changing the timing chain. Some people say change it while your there and other people say not to touch it because timing chains are good for the lifetime of the engine. I was wondering what y'all think.

Water pump replacement doesn't really get you all that close to the timing chain,but at 170k it probably wouldn't be a bad idea to replace it and the guides/tensioner

Don't even think about it IMO. Timing chain is a much deeper job than a water pump.

If you're thinking the serpentine belt, absolutely go for that.

Yes change the serpentine belt. If fhe timing chain isn't causing noise or other issues leave it be.
