I have a 1998 SC300, one morning when I was about to leave for work I saw a coolant leak on the floor. So I decided not to use it and just leave for another time for me to look at it. Last weekend, I was able to jacked it up and removed the plastic cover to see where the leak is coming from.

I started the car did not see any leak. So I let it running for awhile, shut off the engine and restart it again...still no leak. Then, I opened the AC, suddenly, it started leaking from the overflow hose continuously. What do you think it is?

thanks in advance.

You opened the AC? Or did you mean the coolant reservoir? Opening that will sometimes create enough pressure change that coolant will drain from the overflow hose.

I turned the AC "ON". Radiator and reservoir cap were covered.

Sounds like there is an air leak somewhere in your cooling system.
