Water Pump on 2016 Leaf

The yellow warning light came on a few days ago and we took the car to Nissan. They ran diagnostics for 3 hours and finally said the water pump needs replacing. They want $1060. Having read some earlier posts I have some questions that maybe some on this forum may be able to help with.

Is there only 1 pump on the 2016 Leaf? The reason I asked this is while I was still there I did a quick search on my phone and people talk about passenger and driver side pumps. I asked the folks at the dealership about this and they said there's only one.

I also read that people can hear a faulty pump making a noise. But I have not detected a noise. Can the yellow light be something else?

You can probably tell that I don't trust the folks at the dealership very much. They do seem intent on extracting as much money as possible from you, and I don't trust them at all.

Earlier posts on water pumps sound like this is relatively easy to fix, and the part seems to be about $2-300. However, they were discussing a 2012 Leaf. Does anyone know if the 2016 model is any different?

This topic is helpful, and links to the topic you have probably already read, which is even more helpful. The pump location probably changed after 2012, but should be the same for the '13 - 17 Leafs. (Just my guess.)
