Question about 2007 Buick Century

Over Heating Issue

The sensor was replaced, as was the thermostat. Has full coolant and still showing it's overheating, however, it does not gurgle when turned off. Also, the head gasgets are good. Fan does not come on when it begins to over heat. Any suggestions would be appreciated

    Never mind the warranty issue, your vehicle is not a 2007 model, as indicated in the header.



    The last year that the Century was built was 2005 model year.

    Is this vehicle out of warranty already? If not please take to dealer. If it is please tell me if the fan(s) come on when you turn on the air conditioner.

First step would be to get a Wiring Schematic/Diagram for your car, which may be a little hard if its a 2007. Once you've acquired one, you should check the wiring to the Fan, from the Temperature sensor, to the Fan Relay, down to the fan itself. Check for voltage and resistance of all wires involved to try to pinpoint a break in wires, or a short to power/ground in one of them too.

Why is my vy commodore wagon keep over heating ?


First place to look is coolant level. Then try replacing the thermostat - if it does not open completely that will cause inadequate coolant flow resulting in overheating. Is radiator fan working?

Till you locate issue use your heater at full blast with open windows to provide additional cooling for engine.

My 99 alero keeps overheating but the coolant is full, and when i shut it off it starts gurgling what is wrong


Is the thermostat opening at 195 degrees ? Does the radiator fan come on at 220 degrees ?
The gurgling noise is usually air or coolant moving around in the system. If the engine is very hot this noise can be normal.

Heater not working, 'low coolant' light, gurgling noise, overheating....


It may be a early signs of the intake manifold gasket. Did you check your radiator and water pump. Also if there is any antifreeze around your engine, then it's a intake manifold gasket. As for the hazard light thing and turn signal, something has to be replaced there.

2000 daewoo leganza is overheating, leaking anti freeze, and water. what is wrong?


sound like thermostat sticking close.replace thermostat and radiator pressure cap.if already done.you could have faulty water pump.if engine overheating at long slow traffic line or setting at a stand still.the engine cooling fans should be running, check and see if cooling fans running if not,check cooling fans fuses and relays.if all is good,hot wire make sure coolings fans okay.if all is good,code scan vechicle for faulty engine coolant temperature sensor and ecm problems.you need a code scanner where you can check live data check see if coolant temperature sensor reading correctly if engine coolant temperature is 190 degrees the coolant sensor. the scanner suppose to show 190 degrees in temperature if not it reads 80 or 90 degrees the engine coolant temperature sensor is faulty need replacing.if all is good check engine oil if look like milk shake blow head gasket will cause over heating.to be on the safe side i would replace thermostat and radiator pressure cap first.to make sure engine coolant circulating through radiator and engine block.

Overheating


OVERHEATING CAN BE CAUSE BY MANY THINGS LIKE FAULTY THERMOSTAT AND FAULTY RADIATOR PRESSURE CAP,TOO MUCH WATER IN COOLANT SYSTEM NEED 50 / 50 WATER AND ANTIFREEZE.LOOK FOR WATER PUMP WEEP HOLE LEAK, IF COOLANT LEAKING OUT WEEP HOLE WATER PUMP BAD NEED REPLACING.CHECK FOR LOW COOLANT LEVEL, YOUR RADIATOR OVERFLOW JUG SHOULD HAVE COOLANT AT THE FULL COLD MARK IF NOT KEEP ADDING COOLANT INTO COOLANT OVERFLOW JUG UNTIL COOLANT STOP DROPPING AND FULL COLD MARK, IF OVERFLOW COOLANT JUG WAS EMPTY RADIATOR IS LOW ON COOLANT.WHICH CAUSE AIR IN COOLANT SYSTEM KEEPING THE ENGINE COOLANT TEMPERATURE SENSOR FROM BEING SUBMERGE IN HOT COOLANT WHICH TURN ON THE COOLANT FANS.WHEN ENGINE COOLANT TEMPERATURE GET CERTAIN SET TEMPERATURE LIKE 190 DEGREES THE PCM AND COOLANT SENSOR WILL TURN ON COOLANT FANS, IF VECHICLE OVERHEATING COOLANT FANS NOT WORKING EITHER YOU HAVE FAULTY ENGINE COOLANT TEMPERATURE SENSOR CHECK COOLANT FANS FUSE AND RELAYS. YOU CAN CODE SCAN CAR TO SEE IF YOU HAVE FAULTY PCM, FAULTY ENGINE COOLANT TEMPERATURE SENSOR OR FAULTY COOLANT FAN RELAY.IF COOLANT FAN AND ENGINE COOLANT TEMPERATURE SENSOR OKAY,YOU HAVE CORRECT COOLANT LEVEL IN COOLANT SYSTEM, THERMOSTAT AND RADIATOR PRESSURE CAP BEEN REPLACED, YOU COULD HAVE BLOWN HEAD GASKET CHECK ENGINE OIL LOOKS LIKE MILK SHAKE HEAD GASKET BLOWED ALSO WHEN HEAD GASKET BLOWED YOU CAN DRIVE CAR SHORT DISTANCE START OVERHEATING AND YOU LOOSE ENGINE POWER SUSPECT BLOWED HEAD GASKET.

Temperature gauge goes up and down, no over heating, new thermostat and radiator flush..95 dodge caravan


Air is trapped in the engine most likey.Remove the coolant temp sensor located just next to the thermostat housing.Pour coolant in the radiator till no air comes out the hole and replace sensor and top off radiator.it should be full.If problem persists suspect clogged radiator or coolant fan issue.

90 legacy, thermostat keeps showing over heating but there is coolant in reservoir and the engine doesn't seem to be over heating.


hi it could be a faulty water temp sensor, however if the car was overheating you would notice as it would be gurgling or steaming in the engine bay somewhere, it may also be a sick water pump or cracked radiator

Over heating and hard to start


Thermostat needs to be replaced for overheat. If it didn't open, then coolant becomes stagnant then causes engine overheated. Once it was overheated, it destroyed the coolant temp sensor. The signal from this sensor will feed in your ECU to tell it to open your cold start valve to spray extra fuel into engine to assist the start. Replace the Coolant temp sensor for your start problem.

94 cutlass supreme is overheating,all fluids are fine. I did have someone tell me i need 3 motor mounts replaced. could this be an issue of the car overheating?


Over heating can be caused by a faulty thermostat and or weak water pump and dirty radiator and old antifreeze or the radiator fan now working when at idle but should not over heat when driving. Service the cooling system if it has never been serviced before. Replace the thermostat, buy some radiator flush to clean out the radiator and heater core. Just follow the instruction and replace the antifreeze and make sure it's a 50/50 mix water/antifreeze. If you not sure how to mix it 50/50 you can buy them 50/50 premixed. Water boils at 100'C so you need antifreeze mixed with it but antifreeze does not have the same heat transfer as water so you cannot run 100% antifreeze cause it does not transfer heat fast enough and you over heat. Good luck and hope this helps. Keep me posted, Be glad to help, once you service the cooling system and your still over heating, then we look at the water pump.
