How do you add coolant to a Lexus IS250?
Adding coolant to a Lexus IS250 is a straightforward process that helps maintain the proper operating temperature of the vehicle's engine. This guide will walk you through the steps to safely and effectively top up the coolant level in your Lexus IS250.
Identifying the Coolant Reservoir
The coolant reservoir in a Lexus IS250 is typically located in the engine bay, often near the front of the vehicle. It is usually a translucent plastic tank with "COOLANT" or a similar label clearly visible. This is where you will add the new coolant.
Checking the Coolant Level
Before adding any coolant, it's important to check the current level in the reservoir. The coolant level should be between the "MIN" and "MAX" markings on the side of the tank. If the level is below the "MIN" mark, you'll need to add more coolant.
Selecting the Correct Coolant
Lexus recommends using a specific type of coolant for the IS250 model. Consult your owner's manual or contact a Lexus dealer to determine the correct coolant type and specifications for your vehicle.
Adding the Coolant
- Ensure the engine is cool before attempting to add coolant. Hot engines can cause the coolant to spray out, which can be dangerous.
- Slowly unscrew the cap on the coolant reservoir, being careful to avoid any hot steam or liquid.
- Pour the new coolant into the reservoir, being careful not to overfill it. Fill the reservoir up to the "MAX" mark.
- Replace the cap securely and tighten it.
After adding the coolant, start the engine and let it run for a few minutes. This will help circulate the new coolant throughout the system. Check the level again and top up if necessary.
Disposing of Old Coolant
If you need to completely drain and replace the coolant, be sure to dispose of the old coolant properly. Coolant is toxic and should not be poured down drains or onto the ground. Contact your local waste management authority for guidance on proper disposal methods.
By following these steps, you can easily and safely add coolant to your Lexus IS250, helping to maintain the health and performance of your vehicle's engine.
Can you just add coolant to the reservoir?
Remove the cap completely. If the coolant level is low, add the correct coolant to the reservoir (not the radiator itself). You can use diluted coolant by itself, or a 50/50 mixture of concentrated coolant and distilled water. When coolant rises to the cold fill line, replace cap and tighten it until you feel it click.
