The water pump in your 2005 Lexus 330 is used to transfer coolant from the radiator to the engine, helping to keep the engine cool. If your water pump becomes damaged or broken it can cause a serious problem to your vehicle, resulting in the engine overheating. If your water pump is damaged you should look to replace it as soon as possible. You can pick up a replacement part from your local auto store.

Locate the battery underneath the hood of your Lexus. Disconnect the negative battery terminal. This will allow you to work on the car without fear of electrocution.
Remove all of the coolant from the radiator and engine assembly. Ensure the engine is completely cool before carrying this out as a hot engine could result in a burn off the steam or the coolant itself.
