C 220. How do l find the fuse for electric fan?

blocked radiator, blown head gasket, new thermostat in wrong
If the overheating is occurring at standing , low speeds or high rpm low road speed conditions , replace the viscous fan hub as it is not driving the fan properly
If you have electric fans check
bot fuses, engine coolant sensor, relay, fans and wiring

How hot is it getting in degrees F? Some electric fans won't even turn on, till around 220 degrees F. Does the fan turn on at all?
As far as overheating, does the coolant recovery reservoir fill up in a hurry?
Sometimes after opening up the cooling system, you get air in the system that may cause temp gage to react.
What about your thermostat? Did you check for coolant flow through the radiator? Another thought might be a head gasket issue, I'd check everything else first.

if engine over heating coolant over flow jug will boil over you will see steam.sound like you have either faulty engine coolant temperature sensor or could have faulty fans relay or fuse or pcm problem if coolant fans dont turn on.have garage with code scanner that can do a snap shot on coolant temperature sensor check see how hot coolant temperature is see if coolant temperature over 220 degrees engine getting too hot.could have faulty water or blowed head gasket check engine oil on oil dip stick look milkly you have blowed head gasket. i use infra red laser thermometor check see how hot engine is over 107 celsius engine is overheating.

Your electric fan should come on around 220 degrees or so, if it does not you need to replace the sensor on the left front side of the block. The fan should come on immediately if you have AC and turn it on. If it does not check the relay in the fuse box under the hood, and related fuses. Unplug the electric fan and turn the ac on and check for power. It could be your fan motor quit. Usually if the fan does not come on when the AC is turned on, and it does not come on when car reaches 220 degrees, the motor is most likely the culprit.

OVERHEATING CAN BE CAUSED BY LOW COOLANT,TOU COULD HAVE TOO MUCH WATER IN COOLANT SYSTEM YOU NEED 50/ 50 MIXTURE OF ANTIFREEZE AND WATER TO RAISE BOILING POINT.IF COOLANT OKAY, IF VECHICLE OVERHEATING DURING SHORT DRIVE COULD HAVE BAD THERMOSTAT AND FAULTY RADIATOR PRESSURE COOLANT CAP. IF THERMOSTAT OKAY CHECK WATER PUMP IF WATER PUMP WEEP HOLE LEAKING.YOU NEED NEW WATER PUMP.IF VECHICLE OVERHEATING WHILE VECHICLE SITTING IN A LONG TRAFFIC LINE.CHECK TO SEE IF COOLANT FANS RUNNING IF NOT CHECK COOLING FANS FUSE AND RELAYS.IF ALL IS GOOD. YOU COULD HAVE ENGINE COOLANT TEMPERATURE SENSOR CODE SCAN FOR FAULTY PCM. HOT WIRE TO SEE IF COOLANT FANS WORK IF NO FAN MOTOR BAD IF YES COOLANT FANS WHEN HOT WIRED. FAULT COULD BE IN THE COOLANT FANS WIRES MAKE COOLANT FANS RECEIVING POWER IF NOT YOU HAVE BLOWED FUSE OR BAD RELAYS.

If there is bubbles occurring even inside the top part of the radiator (where you have the coolant put in), you may have a leak on your head gasket. You may be loosing coolant through the engine.

If you have the 4.0L six cylinder those run hot. 210-220 degrees. If the cooling system is fine, both fans are working and it's not overheating you can try adding a bottle of "Water Wetter" to the coolant. I also changed my radiator cap to an 18psi which seemed to help run slightly cooler. You find it at the autoparts store.

REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP.CHECK MECHANICAL COOLING FAN.SHOULD HAVE RESISTANCE WHEN TURN WITH HAND.IF FREEWHEELS FAN CLUTCH NEED TO BE REPLACED.CHECK TO MAKE SURE AUXILIARY ELECTRIC COOLING FAN RUNNING HOT WIRE COOLING FAN IF FAN RUNS.YOU HAVE FAULTY THERMO SWITCH LOCATED AT THE BOTTOM OF RADIATOR ON THE LEFT HAND SIDE ON 4 CYLINDER ENGINE FOR V6 ENGINE THERMO SWITCH LOCATED ON THE LOWER RADIATOR HOSE ON THE RIGHT HAND SIDE OF THE ENGINE COMPARTMENT. CHECK FOR BLOWN COOLANT FAN FUSE OR FAULTY RELAY.IF THE AUXILIARY ELECTRIC FAN DONT RUN WHEN HOT WIRED THE ELECTRIC FAN FAULTY.

SOUND LIKE COOLING FANS NOT RUNNING CHECK AND SEE DOES COOLING FANS TURN ON WHEN ENGINE OVERHEATS IF NOT CHECK COOLING FANS FUSE AND RELAY IF BOTH CHECKS OUT GOOD HOT WIRE COOLING FAN.IF IT WORKS.PROBLEM COULD BE COOLANT TEMPERATURE SENSOR- PCM- AND OPEN OR SHORT IN WIRES.IF COOLING FAN DONT WORK WHEN YOU HOT WIRE IT PROBLEMS THE FAN MOTOR.

check your radiator fan if its powering on when engine runs hot. Test if there is power at the fan's electrical connector when car is running and temp guage is at half. If there isnt any power on, check your relays and fuses. Hopefully this helps
