When to Service Your 2003 Lexus LS430 Cooling System

It can be tough to know when to have your Lexus LS430 radiator serviced if you don't know what it does, but it's still extremely important. The radiator is in the cooling system of your car, and it helps your engine temperature stay within a safe range. When the radiator isn't working properly, your engine can overheat and potentially break down.

Staying on top of routine radiator maintenance for your 2003 Lexus LS430 is essential for long-term engine health. To keep your radiator functioning, Lexus recommends replacing your antifreeze or coolant at scheduled intervals but you can also take note of any signs your radiator is going bad.
