Why does my 2002 Ford Ranger cooling fan run all the time?
If it runs even with the car shut off it is probably a bad switch. If it runs all the time with the engine running it is probably a bad temp sensor.
Any ideas with 1995 jetta diesel radiator cooling fan which runs all of the time even with sensors at rad and at engine block disconnected?
Volkswagen has a hardwired cooling system in a good number of their models, the cooling fan will run several minutes after driving. Especially if the engine is overheated, you can expect the fan to resume after it has initially shut off... So make sure to disconnect the battery before any repairs following running the engine.

2000 grand caravan engine cooling fans run long after car is off and runs battery the down?
I would check the Cooling Fan Switch/Relay. Sounds like it is a bad switch and stays 'on' well after it is needed, if it is running the battery down.
98 Chevy cavalier runs hot in traffic or on interstate fine around town replaced radioator last year did not cure it?
When it's running hot you should hear the cooling fan running, if not that is your problem. If the cooling fan does not operate check the fuses, cooling fan relay, cooling fan switch and cooling fan motor. One of them is at fault.

As long as the engine is running, this is normal.

If it runs all of the time, even if the engine is first started inthe morning,Then the temp sensor that controls the fan may be gone.

Do both cooling fans run at same time. Do one run until the car gets hot.99chrysler LHS?
I can't speak for that SPECIFIC car and model but on most cars with two fans, one is driven by the engine belt and runs whenever the engine is running. The other runs electrically and can turn on (usually) if the key is in the ignition. There is a relay and a controller that tells that fun if the engine needs cooling. On some cars this fan will run even if the key is not in the ignition; i.e. parked and the driver away from the vehicle. It should stop when the sensor running it decides the engine is cool enough. Both fans are electrically driven and have two speeds. The fans operate at a lower speed until a certain temperature is reached, at which time they both switch to high speed. The two fans are always on the same setting: Off, Low or High.
2000 Chevy truck 5.3 engine runs hot when ac is turned on?
Maybe your cooling system needs to be flushed out.
Engine starts and runs for a few seconds and then stops this keeps happening and engine won't keep running What is wrong?
Fuel pump
Does engine have to run for fuel pump to run?
If the vehicle has an electric fuel pump, then no, it runs no matter if the engine is running or not, but it will only run for a few seconds unless the engine is started. However if the pump is mechanical then the engine must be running for the pump to work.
