Frequently asked questions

Frequently Asked Questions

6 common questions answered

What are the signs a 2018 Lexus NX 300h needs a coolant service?Signs include a higher-than-usual temperature gauge, a sweet smell, a puddle under the front of the vehicle, or coolant that looks rusty, cloudy, or low.

These symptoms can indicate depleted coolant or a leak, so a pressure test helps determine the cause. Do not open the cooling system when it is hot or recently running because it remains pressurized. Check it only when cold and arrange an inspection if a warning sign appears.

  • Temperature gauge running higher than usual
  • Sweet smell or puddle beneath the front of the vehicle
  • Rusty, cloudy, or low coolant in the reservoir
What is included in a coolant service on a 2018 Lexus NX 300h?Coolant service drains and refills the system with the manufacturer-specified coolant type and concentration, pressure tests for leaks, and inspects related components.

The inspection covers the hoses, cap, radiator, and water pump area. Together, these steps evaluate coolant condition and help separate routine service from a leak requiring repair. You can schedule service at Nalley Lexus Roswell for the complete check.

  • Drain and refill with the specified coolant
  • Cooling-system pressure test
  • Inspection of hoses, cap, radiator, and water pump area
How often should the coolant in a 2018 Lexus NX 300h be changed?The manufacturer's published maintenance schedule for the 2018 Lexus NX 300h settles when coolant should be flushed or replaced.

That schedule is the authority for routine replacement rather than appearance alone. Coolant condition can also be tested during a service visit between scheduled points, especially when symptoms appear. A test can help identify whether service is due or whether a leak needs repair.

  • Follow the manufacturer's maintenance schedule
  • Test coolant condition during a service visit
  • Inspect for leaks when the level drops or symptoms appear
What kind of coolant does a 2018 Lexus NX 300h use?The manufacturer specifies the coolant type for the 2018 Lexus NX 300h, and that specification should guide the service.

Coolants are not interchangeable, so the correct product should be confirmed for this vehicle before a refill. Colour is not a reliable guide to what is in the bottle. Nalley Lexus Roswell can perform the refill using the specified coolant type and concentration without relying on colour as identification.

  • Use the manufacturer-specified coolant type
  • Do not treat different coolants as interchangeable
  • Do not identify coolant by colour alone
Can I just top off the coolant in a 2018 Lexus NX 300h?Topping off restores the coolant level but does nothing for the additive package, and a level that keeps dropping indicates a leak rather than normal consumption.

A low reservoir should be evaluated instead of repeatedly filled without finding the reason. The system is hot and pressurized after running, so any check should be performed cold. A pressure test and component inspection can distinguish depleted coolant from a leak that needs repair.

  • Top-off restores level only
  • Dropping coolant suggests a leak
  • Check the system only when cold
