Re: I just purcgased a 1990 Lexus ls 400 and the coolant...
It does sound like the sensor is either dirty inside the tank or bad. You will have to remove the overflow tank and the sensor is torward the bottom of the tank and easily replaced.

If u have repaired coolant problem and light well not reset. Problem is not fixxed then. Look for something minor like cap on not holding correct pressure overflow tank has a sensor inside that may be bad.
I believe what this symbol is the radiator. It comes on when the coolant level is low. Take a look at your radiator coolant level and if low add some to the full mark. Do this when the engine is cold to avoid getting burned from hot water and steam.
I would inspect your wires at the starter. If you live up north then corrosion is bad, clean all wires going to starter. then clean wires to back of alternator. I seriously doubt that alternator is the problem, but if you remove it you can have it tested for free at most parts stores.
You're alternator has gone bad and the vehicle was running on battery power. The "clicking" sound is your now dead battery that does not have enough power to turn over the starter. You might also want to check your power steering pump for leak. This is a know problem with early LS400s and will most likey be the cause of the alternator failure. I just dropped $1050.00 to fix the very same promblems you have.
