What is the role of a radiator?

The radiator is the primary part responsible for cooling your Lexus RX330 while you drive. The radiator helps to cool the coolant down that flows through the engine block. Without this system, the coolant wouldn't reach a low enough temperature and would go back into the engine while still hot. This could negatively affect the engine and various other components.

What are the various parts of a cooling system?

It's important to know the various parts involved with cooling your RX330 model.

  • Coolant bottle: Where all of the coolant is kept.
  • Overflow tank: Where excess coolant flows.
  • Radiator cap: The cap that goes onto the radiator to form a seal.
  • Hoses: The various hoses that help the coolant travel to the different components.
How do you replace a radiator part?

Replacing Lexus RX330 radiator parts is dependent on what part is affected. You will want to know what the different parts are when you open the hood. You can use your owner's manual to help identify all of the parts. Some parts may require moving components such as the engine cover, hose, or the front bumper out of the way. You should always follow the instructions that are provided to you and use the suggested equipment and tools to help you with the task.

What is a genuine OEM part?

Genuine OEM parts are those that are made specifically for Lexus. You can find OEM parts that are just like what was put into your Lexus RX330 at the factory. In addition to OEM parts there are aftermarket parts, which includes all of the other brands that make parts for your radiator.
