With age, the water pump on your 2001 Toyota Corolla will start to wear out and you will need to replace it.
Doing so, requires some skill, as the water pump is located in a pretty tight space an you will also need to unmount a few parts off the engine. So if you don’t think you can handle it, visit a service. Else, grab your toolbox and buy a replacement water pump compatible with your model. Here’s how to do it:
- Disconnect the battery terminal
- Remove the engine plastic cover by unscrewing the two bolts
- Take a 19 mm socket ratchet and loosen the accessory belt tensioner
- Remove the accessory belt
- Next, remove all cable connections from the alternator
- Unscrew all the bolts fixing the alternator on the engine and remove it to have better access to the water pump
- Remove the bolts from the water pump and take it out
- Don’t forget to replace the water pump's sealing gasket
- Put the new water pump in and screw it in place
- Do the same with the alternator
- Put the accessory belt back and tension it.
