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

I got a 1987 Cadillac sedan Deville and just put a new start on it it will start up and run great but if u turn it off it takes forever to start back plz help


sounds like a problem with the fuel getting overheated and evaperating when turned engine off , check the engine cooling system is pumping through the fuel intake manifold section as a starting point, check that the engine cooling fan runs on after turning engine off as this cools the engine down to stop the fuel evaperating in the fuel lines etc

My 2002 mitsibishi cedia has started having a fan on after the engine is turned off. Why is this happening?


Fan wil be controlled by a temperature sensor, if you have been driving engibe will gethot and start the fan running, as soon as you stop driving the heat does not drop so quickly so fan remains running until the temp sensor detects that the temp has dropped below the threshold. If the fan just runs even after engine itself has cooled down may be a problem with temp sensor. suggest to leave car for about 10 to 20 mins after engine is shutoff and then go back and check if fan still running

Car star when is cold but if I stop the engine after is hot it will not start until cool of again


If you mean that it starts fine when cold, but if you stop & turn off the engine (to to pop into a shop for example) then try to restart and get absolutely no turning over, then you need to replace your battery. It has a short or crack which is expanding when hot creating your problem.

I have a honda accord 1993 when you turn the engine off the coling fan works and that time if you whant to turn it on doesnt turn on but after the fan stop the engine can turn on i change the tun up the...


Bring the vehicle into a repair shop the technician has to duplicate the situation before he /she can conduct testing. I don't think your cooling fan is the problem . I'm leaning towards engine main relay.(located under the dash board) contacts getting hot and once you turn off car there is no ventilization inside the vehicle ( a/c air blowing on relay) to cool it down. The only
draft is coming from cooling fan to cool off its contacts. Pretty soon you'll have longer wait periods before you can start the vehicle . Unless you live in the Artics.lol

Hi i got a nissan interstar diesel 2007 mod when i start it hot or cold i need a small squirt of kwikstart the van olso cut out wile driving if i turn the key of and on again it emediatly start.


To me like some loose electrical connection is resposible for this problem. Check the battery terminals for tightness and the fuses to internal heater. There might be a halfblown fuse or loose connection which is insufficient to make it possible to start the engine, but once in motion the vibration of the var provides enough to keep the connection going to start the engine because after having started the engine, it has no active role to play until you swictch off the engine. On starting time its required. So check sor the loose connection to the heater and the compressor, both of which comes into play in starting the engine...sodeep
