JUST BOUGHT A 92 ES300. AFTER DRIVING THE CAR AND THE ENGINE GETS HOT, COOLANT BEGINS LEAKING FROM THE OVER FLOW TANK. AFTER THE ENGINE LOSES ENOUGH COOLANT, IT BEGINS TO OVER HEAT. THE HOSE ON THE CAP OF THE OVER FLOW TANK IS BROKEN. BEFORE THE HOSE ON THE CAP BROKE COMPLETELY, THE CAR WOULD BEGIN TO OVER HEAT WITH THE AIR CONDITIONER ON. COULD SOMEONE PLEASE HELP TROUBLESHOOT THIS PROBLEM.. I THOUGHT THAT IT COULD BE THE THERMOSTAT OR RADIATOR FLUSH NEEDED. IF SO, COULD U TELL ME HOW TO GET TO THE THERMOSTAT AND WHERE THE RADIATOR DRAIN PLUG IS LOCATED.. THANKS...........
i jus bought a 92 es300 that did the same thing. it turned out to be a bad intake manifold gasket.
