SOURCE: 2001 chevy malibu- when car starts cooling fans do not come on but then do

your coolant temp sensor on the engine block is probably faulty, however, keep in mind that if it really isn't all that hot outside they may not need to turn on. Once you activate the A/C the fans come on automatically since they have to cool the condensor...

If your car is not overheating do not worry about it.

SOURCE: 2006 chevy cobalt woulnt start lock light is on

Are you using the original key that came with the car? The chip in that key may have gone bad. Try using the spare key that should have come with the purchase of the car. You may also be having battery issues. If all else fails....call the people who really know how to rape you...DUM Dum dummmmm....the dealer

08 Chevy Cobalt wont start. Battery is good.?


Generally speaking, if the starter was dead it would not jump start.
Sounds like the key switch or the neutral safety switch.
You would need to know if the starter has power when the key is in the start position.

2006 chevy cobalt the engine cooling fan is not coming on


Check with warm engine and off by touching on your radiator vents whether is in all places same temperature. If not check whether you have air in the coolant which needs bleeding,or not good coolant circulation,caused either by clogged radiator,not good water pump,or faulty thermostat.By having these things it is the possibility the fan switch not getting the correct temperature to allow the fans to start. the last thing if everything is working,the possible is the fan switch itself.

2007 CHEVY COBALT CHECK ENGINE LIGHT IS ON AND THE FAN IS CONSTANTLY RUNNING


this is normal for most vehicles, it is because the water temp in radiator continues to rise after you shut the engine off. would not worry about it unless it dose not shut off at all. or never runs

I HAVE A 2007 CHEVY COBALT THE CHECK ENGINE LIGHT CAME ON I CHECKED THE COOLANT TEMP GAUGE THE DIGITAL GAUGE READING WAS ONLY SHOWING THREE BROKEN LINES. I CHECKED COOLANT LEVEL WHICH WAS FINE. ENGINE DID...


I had this problem with a 2007 Chevy Cobalt. I changed the coolant sensor and even though the check engine light went out I still had a reading of "---" on the coolant gauge. The problem is most likely one of three things: a low coolant level, a bad coolant sensor, or the thermostat needs to be replaced. The only other possible thing it could be is a bad BCM (Body Control Module) which in that case you would most likely be having other weird problems.

The Thermostat and the sensor are both very easy to get to and replace. Take off the engine cover by removing the oil cap and they are both to the rear of the engine on the driver's side. They are right next to each other.

Hope this helps!
