Engine overheating Fan motor replaced but engine still overheating

Disconnect the ECT (engine coolant temperature) sensor with the key on, the fan should start in default and stay running, if it doesn't run check for voltage at the fan motor connector, if voltage is present and the connector is not burned looking or discolored replace the fan motor. If the fan has no power try jumping the relay socket to power up the fan motor circuit, if that works replace the fan motor relay under the hood. You gave no make, model or year and engine type so that is about all I can help.

on that motor they are prone to blowen head gaskets you need to do pressure check of the cooling system

FIRST OF ALL I WOULD REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP THEN CHECK SEE IF COOLING FAN RUNNING.WHILE CAR OVERHEATING. IF NOT CHECK COOLING FAN FUSE AND RELAY.IF ALL IS GOOD THE ENGINE COOLANT TEMPERATURE SENSOR COULD BE FAULTY.HOT WIRE SEE COOLANT FAN WORKS IF NOT, COOLING FAN MOTOR BAD NEED REPLACING.IF COOLING FAN MOTOR WORKING PROBLEM COULD BE IN FAN MOTOR WIRING OR PCM FAILED.

Do you think that it's overheating because the temperature light is on? If so, then it's possible that you have a bad temperature sensor and not an overheating engine.
Look for other signs of engine overheating :
1. Sluggish engine operation.
2. Detonation upon acceleration (pinging).
3. Rough, uneven engine idle.
4. Coolant boiling in overflow tank.
If your vehicle is experiencing these symptoms, then overheating is indicated. One of the most common cases of overheating is a bad thermostat. Another common problem is a faulty cooling fan or fan circuit. The cooling fan can be checked by running the engine at operating temperature and turning on the AC control. if the fan does not come on, then a problem with the fan circuit is indicated. The thermostat can be checked by placing a cooking thermometer on the motor near the upper radiator hose where it attaches to the motor. the temperature should not go above 225deg. If it does, then replace the thermostat. If the temperature stays at or below this rating, then replace the temperature sensor. I hope that this information helps you with your problem and thank you for using Fixya.com.

WARNING : Be very careful when working around cooling systems when the engine is at operating temperature. DO NOT open the radiator cap (if equipped) or even the overflow tank cap when the system is hot. Always wear safety glasses. Remember that electric cooling fans can operate at any time, even after the engine is off. Keep hands away from fan when working in the engine compartment.

WHEN CAR STARTING OVERHEATING MAKE SURE COOLANT LEVEL DIDNT GET TOO LOW. IF NOT I WOULD REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP IF OVERHEATING WHILE SITTING IDLING COOLING FAN NOT COMING ON.CHECK COOLING FAN FUSE AND RELAY IF ALL IS GOOD.CHECK COOLING BY HOTWIRING IT.IF RUNS YOU HAVE A BAD COOLANT TEMPERATURE SENSOR OR FAULT IN WIRE CIRCUIT.IF FAN DONT RUN WHEN HOTWIRED REPLACE FAN MOTOR.IF CAR STILL KEEP OVERHEATING CHECK ENGINE OIL LOOKS LIKE MILK BLOWN HEAD GASKET.IF OIL LOOKS OKAY YOU NEED RADIATOR AND ENGINE FLUSHED OUT.

It could be the radiator fan motor if all sensors and relays have been changed.......unplug the coolant temperature sensor the fan should come on and stay on unless the motor is bad or it is not getting electrical current.

Is the water pump leaking coolant? If not, then why do you think it's bad?

If the engine is overheating, there are several other things to look at before you consider the replacing the water pump.

Are the fans electric motor driven, or fan belt driven? If fan belt driven, replace the fan clutch. If electric motor driven, check the fan control module and/or fan motors to make sure all is good there. Fan control module tend to fail in weird ways, so if nothing is wrong with the motors, replace the module.

Always, always, replace a thermostat that has overheated. Once overheated, they consistently fail. Make sure you properly refill the radiator with coolant after the stat is changed.

Check that the bottom radiator hose does not collapse.

Check the radiator for corrosion. Boil the radiator out, or have it done, or replace the radiator.

replace your cooling fan motor relay because if you dont eventually your radiator will explode and this will cause your engine block to crack and then if your fan isn't blowing the engine will continue to overheat and the engine will seize and then you need a new engine. A cooling fan motor relay is around $30.

Is the engine itself hot? or the car? If the engine is warm, check the engine coolant, and see if their are any holes or leaks..

IT COULD BE THE FAN FUSE OR FAN RELAY, IF THE FAN IS DRIVEN BY THE ENGINE TRY CHECKING THE FAN CLUTCH. IF THE FAN SPINS FREELY WHILE IT IS COOL, THEN WAIT FOR THE ENGINE TO HEAT UP AND SHUT THE ENGINE OFF AND TRY TURNING THE FAN BY HAND. IF THERE IS LITTLE OR NO RESISTANCE THEN REPLACE THE FAN CLUTCH. IF THE FAN IS ELECTRIC THEN REPLACE THE FUSE AND RELAY LOCATED UNDER THE HOOD IN THE FUSE PANEL. HOPE THIS HELPS. PLEASE KEEP ME POSTED. THANKS FOR AN HONEST RATING AND FOR USING FIX-YA. BEST OF LUCK.
