Frequently Asked Questions

6 common questions answered

What are the signs a 2018 Lexus IS 300 needs a coolant service?Signs include a higher-than-usual temperature gauge, a sweet smell or puddle, and coolant that looks rusty, cloudy, or low.

These symptoms can indicate depleted coolant protection, a leak, or another cooling-system condition. The system is under pressure and hot after running, so checking it should be done cold. A service visit can determine whether the vehicle needs coolant maintenance or repair.

  • Temperature gauge running higher than usual
  • Sweet smell or puddle under the front of the vehicle
  • Rusty, cloudy, or low coolant in the reservoir
What is included in a coolant service on a 2018 Lexus IS 300?The service drains and refills the coolant, pressure tests the system, and inspects the hoses, cap, radiator, and water pump area.

The refill uses the coolant type and concentration the manufacturer specifies for this vehicle. Pressure testing helps identify leaks that a level check may not reveal. The inspection helps separate routine coolant maintenance from a condition requiring further repair.

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

That schedule is the authority for replacement timing on this vehicle. Coolant condition can also be tested during a service visit between scheduled points, especially if warning signs appear. A pressure test can help identify a leak rather than simply confirming that service is due.

  • Follow the manufacturer's published maintenance schedule
  • Request a coolant-condition assessment between scheduled points
  • Book an inspection if the level drops or the gauge runs hot
What kind of coolant does a 2018 Lexus IS 300 use?The manufacturer specifies the coolant type for the 2018 Lexus IS 300, and the correct product should be used for the vehicle.

Coolants are not interchangeable, so selecting fluid by appearance can create a compatibility problem. Colour is not a reliable guide to what is in the bottle or what the vehicle requires. Park Place Lexus Grapevine can service the system using the manufacturer's specified coolant type and concentration.

  • Use the coolant specified by the manufacturer
  • Do not treat different coolant products as interchangeable
  • Do not use colour alone to identify coolant
Can I just top off the coolant in a 2018 Lexus IS 300?Topping off restores the coolant level but does not restore the depleted additive package or address a leak.

A level that keeps dropping indicates a leak rather than normal consumption and calls for an inspection. The cooling system is under pressure and hot after running, so do not open it then; checking should be done cold. A technician can assess coolant condition and pressure-test the system.

  • Adding coolant changes the level, not the additive condition
  • A recurring low level can indicate a leak
  • Check the system only when it is cold
