check top radiator hose goes to thermostat housing sound like its leaking if your engine leaking from left driver side on top of engine it has to be top radiator thermostat hose leaking.wait until engine cool down replace top radiator hose see if coolant leaking still occur if so you could have radiator leak.
If the hose itself is leaking replace the hose. If its the plastic fitting, remove the hose, remove the plastic fitting from the intake (should clip in), replace the o-ring on the fitting, reinstall the fitting into the intake, and install the hose onto the fitting.
ENGINE NOT GOING TO START IF GET TOO HOT FIRST THING I WOULD REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP THEN ADD COOLANT UNTIL COOLANT LEVEL CORRECT THATS WHEN THERMOSTAT OPEN UP AND TOP HOSE HOT.CHECK FOR LEAKING RADIATOR HOSES CHECK TOP RADIATOR HOSE CHECK BOTTOM RADIATOR HOSE.CHECK FOR LEAKS AROUND THE RADIATOR LOOK DOWN BELOW COOLANTS FANS CHECK FOR LEAKS AT RADIATOR CORES OR LEAKS AT THE RADIATOR PLASTIC SIDE CONTAINERS. CHECK FOR LEAKS AT WATER PUMP WEEP HOLE AND CHECK FOR LEAKS AT THE HEATER HOSES AROUND ENGINE BLOCK TO THE HEATER CORE HOSES. THERE IS A REASON CAR OVERHEAT.IF CAR OVERHEAT WHILE DRIVING YOU HAVE FAULTY THERMOSTAT OR LEAKING OUT COOLANT OR BLOWN HEAD GASKET.IF ENGINE OVER HEAT WHILE SITTING DURING A LONG IDLING PERIOD.YOU COULD HAVE FAULTY COOLANT TEMPERATURE SENSOR OR FAULTY COOLING FAN FUSE OR RELAY.HOT WIRE COOLANT TO SEE IF IT RUNS IF NO REPLACE FAN MOTOR. IF YES FAN MOTOR COULD HAVE FAULTY WIRE OR PCM FAILURE. CHECK ENGINE CRANKCASE IF OIL LOOKS LIKE MILK SHAKE ENGINE HEAD GASKET LEAKING.
Find the radiator hose that comes out of the top corner of the radiator on the drivers side of the car. The hose goes from the radiater to the engine. Where the hose goes on the barb bolted to the engine with two bolts, if you take the hose off and then the two bolts the thermostat will be between that hose barb and the engine block.
when your at a light and apply the brakes does the running get worse? if so you have a vacum leak. there is a temperature switch should be installed in the intake near where the top hose from the radiator goes in the motor this is like a 15 buck part. this will have 3 to 5 vacum lines to it make sure that these are not cracked or split and are all hooked up. one of these goes to your distributor check this hose.
another place that can cause this is in the air intake system there is a airflow meter this will create these kinds of problems as well. with the car hot and running pulle the hose off of one side of this and see where the butterfly valve is located it should be almost full open if not replace it
