Hello,

It could be the water pump, but also it can be the cooling fans.
Do you know if they are coming on as they supposed to?
First you need to check the relays for the cooling fan and verify that they are good.

Here is an article on how to test relays:

If the relays are good then you will have to check to see if there is power going to the fan.
I have attached the diagrams for the relay and fan.

You can also test to see if you have a blown head gasket.
Here is a helpful article on how to to that:

Please let me know of any questions.

Thank you.
