Why does the radiator in my GS450h sound like it’s rumbling or boiling?

There’s rust in my GS450h radiator. Should I be worried?

Yes. Having rust in your Lexus GS450h radiator can cause leaks, a reduction in cooling efficiency, and even radiator failure.

To help prevent rust from becoming a major issue, it's important to properly maintain your radiator system.

Is It Time for Service on My 2011 Lexus GS450h Cooling System?

Not sure what a radiator does? That makes it difficult to know when to have your Lexus GS450h radiator serviced, but it's still extremely important.

Keeping up with regular radiator maintenance in your 2011 Lexus GS450h is essential for long-term engine health. Lexus recommends that you replace coolant (also called antifreeze) at certain intervals, but it’s also wise to keep an eye out for signs of a failing radiator.
