How do you flush the coolant in a Lexus?

Flushing the Coolant in a Lexus
To flush the coolant in a Lexus, you can follow these general steps:
1. Gather the necessary materials: You will need one gallon of distilled water, one gallon of coolant, a flushing kit, a hose, and scissors.
2. Prepare the vehicle: Park the car on an incline if possible, with the front higher than the back. This will help reduce air bubbles in the cooling system. Allow the car to sit for at least two hours after driving before opening the coolant system to avoid any potential burns.
3. Locate the upper heater core hose: Open the hood and find the upper heater core hose. This hose will be hot if the car is even lukewarm. Slice it open and strap the flushing tee into it. Choose the largest tee that fits.
4. Connect the flushing kit: Connect the flushing kit to the flushing tee. The kit will have specific instructions on how to attach it properly.
5. Flush the system: Turn on the hose and let the water flow through the system until it runs clear. This will help remove contaminants from the system. Be sure to follow the instructions provided with the flushing kit for the specific procedure.
6. Drain the system: Once the system is flushed, remove the flushing kit and reattach the upper heater core hose. Locate the radiator drain plug (petcock) and drain the water from the radiator. Close the drain plug once all the water has been drained.
7. Refill with coolant: Fill the radiator with a 50/50 mixture of coolant and distilled water. This will ensure the proper concentration of coolant in the system. Be sure to follow the manufacturer’s recommendations for the type of coolant to use in your specific Lexus model.
It’s important to note that the maintenance interval for coolant flushes may vary depending on the specific Lexus model and the type of coolant used. Consult your vehicle’s owner’s manual or contact a Lexus dealership for the recommended maintenance schedule for your vehicle.
Please keep in mind that these steps are a general guideline, and it’s always recommended to consult the vehicle’s owner’s manual or seek professional assistance for specific instructions tailored to your Lexus model.
