Lexus GS Coolant Loss

I had a similar issue with my Lexus GS. I would inspect the water pump and radiator hoses for any signs of leakage. It's also possible there could be air pockets in the system. Have you checked the cooling fan operation?

Thank you for your insight. When you had the issue with your GS, did the coolant level drop rapidly, or was it a gradual decline? I am trying to assess the urgency of the repair.

In my case, the coolant loss was gradual but noticeable. I recommend taking it to a workshop as soon as possible to prevent potential engine damage. I ended up paying 52€ for them to fix the leak.

I appreciate the confirmation. I will schedule an appointment with the workshop to have the cooling system thoroughly inspected and the leak addressed. Thank you for your help!
