Radiator fans randomly shut off


  • Relays carry high-amperage current controlled by a low-current switch
  • When a faulty relay is not replaced, the circuit will either be non-functional or remain engaged. here's your relay you need.

My 99 alero v6 is over heating not leaking ight mite be hoses or thermostat . or head gasket but when it overb heats the smoke comes from the top of the engine


REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP.IF CAR OVER HEATING WHILE IN MOTION.MORE LIKELY ITS THE THERMOSTAT,LOW COOLANT IN RADIATOR OR COOLANT SYSTEM,BAD WATER PUMP,WATER PUMP WEEP HOLE IS LEAKING, WATER PUMP NEEDS REPLACING.CHECK ENGINE OIL,IF OIL LOOKS LIKE MILK SHAKE YOU HAVE LEAKING HEAD GASKET.IF CAR IN PARK AND OVER HEATS WHILE IN A LONG TRAFFIC LINE OR.BANK DRIVE THROUGH COOLANT FAN NOT TURNING ON, BECAUSE THE ENGINE COOLANT TEMPERATURE SENSOR FAULTY.CODE SCAN CAR FOR FAULTY COOLANT FAN RELAY OR FAULTY PCM. CHECK COOLANT FAN FUSE, AND HOT WIRE THE COOLANT FAN TO MAKE SURE ITS WORKING.IF COOLANT FAN DONT WORK WHEN HOT WIRED. COOLANT FAN NEEDS REPLACING. REPLACE BOTH RADIATOR HOSES, REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP.BUY NEW COOLANT ADD 50/50 WATER AND COOLANT.IF ENGINE OIL HAS ANTIFREEZE IN IT.REPLACE ENGINE OIL AND OIL FILTER TO KEEP FROM LOCKING UP THE ENGINE.GET CAR FIX.DONT KEEP DRIVING IF IT KEEP OVER HEATING,ENGINE DAMAGE WILL OCCUR.I HOPE INFORMATION I GAVE YOU WILL FIX PROBLEM.PROBLEM COULD BE LEAKING RADIATOR HOSES BUT CHANGE THERMOSTAT THATS FIRST THING I WOULD CHANGE BECAUSE IF IT CLOSED, ENGINE WILL OVER HEAT AND CRACK CYLINDER HEAD OR CRACK PISTON, COOLANT NEED TO CIRCULATE THROUGH THE ENGINE TO TAKE AWAY THE HEAT FROM ENGINE.

REPLACE THERMOSTAT.ITS STICKING CLOSE TO KEEP COOLANT FROM CIRCULATING THROUGH ENGINE AND RADIATOR. THE FANS SHOULD COME ON WHEN VECHICLE SETTING AT A LONG IDLE.THE COOLANT TEMPERATURE SENSOR GET TO CERTAIN TEMPERATURE WHICH WILL COMPLETE CIRCUIT PCM SEND POWER TO COOLANT SENSOR THEN TO COOLANT FANS RELAYS AND FANS.IF VECHICLE OVER HEATING WHILE MOVING THERMOSTAT FAULTY.IF YOU TURN AC AND COOLANT FANS DONT RUN CHECK COOLANT FANS FUSE AND RELAY.IF COOLING FANS DONT TURN ON WITH AIR CONDITIONER ON EITHER COOLANT TEMPERATURE SENSOR FAULTY OR PCM FAULTY.IF ALL LOOKS GOOD.IF ENGINE OIL LOOKS LIKE MILK SHAKE.YOU HAVE BLOWN HEAD GASKET.

Not sure if radiator fans are working, car overheating. which fuse do I check?


LOOK UNDER THE HOOD IN THE ENGINE COMPARTMENT. ON DRIVER SIDE FOR FUSE BOX.LOOK ON FUSE BOX COVER IT HAS LOCATION FOR FUSES AND RELAYS.MOST TIME PROBLEM WITH COOLING FAN CIRCUIT WILL CAUSE CHECK ENGINE LIGHT.BAD ENGINE COOLANT TEMPERATURE SENSOR WILL CAUSE COOLANT FANS NOT TO TURN CAUSE OVERHEATING. ON.REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP SEE IF STOP OVER HEATING. IF ALL LOOKS GOOD HOTWIRE COOLANT FANS MAKE SURE FAN MOTORS ARE GOOD AND NO SHORTS AT FAN CONNECTOR WIRES.

1999 Olds Alero. Low coolant light comes on and stays on even though its full. Starts running hot to the 3/4 mark. When the heater is turned on it cools off. Could this be the thermostat or the water pump.


TAKE RADIATOR CAP OFF WITH ENGINE COLD AND CHECK WATER ..MAKE SURE RADIATOR NOT BLOCKED,,PLASTIC BAG ETC. THIS SOUNDS LIKE LOW WATER OR RADIATOR ..STOPPED UP INSIDE ..IF YOU HAVE GOOD HEAT IT'S FULL OF WATER. REPLACE T STAT B4 RADIATOR..IT'S CHEAPER. ALSO CHECK FOR RADIATOR COOLING FAN OPPERATION..I,M RULING OUT THE WATER PUMP.

1999 Olds Alero leaking coolant and running rough


in my experience it sounds like a head gasket problem it maybe leaking into the cylinders or could be a small leak from one of the hoses I would do a compression test just to make sure and then pressurize the entire system using radiator and coolant tester if pressure holds then its not a leak as far as the fans go just have the car running when it reaches the middle of the temp gauge it should come one if not you may need to run check on temp sensor or fan switch and fans them selves I would follow repair manual troubleshooting section on heating and cooling haynes or chiltons will do.
