For comfort and safety in the cold months, it is important to keep the heating system in your Lexus in good working condition. Here are some tips to help you maintain and ensure the effectiveness of your Lexus’s heating system.

Check Coolant Level: Not having enough coolant (antifreeze) can lead to insufficient heat inside the cabin. Make sure the coolant is at the recommended level for your specific model vehicle.

Flush Cooling System: Have your local Lexus repair shop flush the cooling system periodically to help remove debris and contaminants that may affect the heater’s performance.

Check Thermostat: Your thermostat may need some attention if it feels like it is taking a long time for your Lexus to heat up. This may be due to a faulty thermostat, so be sure to have an experienced ###name## technician check this out.

Heater Hose Inspection: Leaks, cracks and bulges may cause problems to the heater core. Damaged hoses will need to be replaced.

Heater Core Inspection: Leaks and clogs of the heater core will result in a poor heating performance, have this inspected.

Check Blower Motor Functionality: If you notice reduced airflow or strange noises coming from this component, you may need a replacement.

Warm Up Vehicle: Let your Lexus warm up before you take it for a spin. This will help let the engine reach optimal operating temperature and ensure that the heating system is warmed up for your comfort.

Whether it’s from low coolant level or a malfunctioning heater hose, you should not have to suffer from the cold when driving. Any qualified Lexus service shop will be able to inspect all of these components for you and make the necessary repairs.
