1. Coolant Leaking from Weep Hole: It's the easiest way to see whether the water pump is in good condition.
2. Leaks Around the Mounting Gasket: The same as the weep hole leakage, it also visually shows that your water pump needs to be replaced.
3. Loose or Wobbly Pump Assembly: A common way to detect a failing water pump is to grab it physically and shake it by hand to see if there is a slight movement.
4. Squealing or Grinding Noises: To check its function, you can carefully listen to see if the engine has strange noises.
5. Internal Corrosion and Rust: Additionally, you can tell through the color and appearance. Discoloration and rough surfaces both indicate it needs replacement.
