Hi,
Really need help on solving the problem about the coolant lamp turns on and off. I made sure the resonator was full with coolant. However, after driving a about 25-30 minutes, the lamp would turn on. I changed a new radiator cap, new thermostat, same problem, but could not find any leaks. Any help would be appreciated. Thank you very much.

Welcome to the club movies_fun
I think something might be clogged in the radiator tubes you might need to get them drain or flushed.This job might cost alot and it will take the mechanic about 6 hrs to do for the 90-94 LS.
Make sure you are also using the right coolant,because Lexus uses a special kind that you cannot get in stores.
Also you could check the sensor of the coolant that is on top of the coolant box,up plug it and plug it back in,it could also be dirty.
There might be others that might give you more info like Loule
