Engine cuts out when the electric cooling fan starts

The car drives perfectly until you get into conjested traffic, the electric operated fan cuts in to reduce the engine temperature. It is then the engine cuts out . It will re starts but cuts out again. Once left for 10 - 15 minutes it will restart without incident as long as the fan is not operating. A warning light on the dash does appear. It is an oblong box with a zig zag going through the middle and a ziggly line beow. Can you help

Check all ground connections and clean them thoroughly. If I was a gambling man, I would lay down money on it being a bad ground. It likely is a combination of all the ground connections being poor.

W\hen car gets hot and we turn it off it wont start again until it cools down. It takes about 13 to 20 min before it will restart.??? Please help me


{: ) The engine control module is programmed to protect the engine by disabling the starting system whenever it detects that the engine temperature is beyond safe limits. Depending on how fast the engine cools, it will resume normal starting after cooling down for a while.
A diagnostic scan tool readout can give you a quick idea about the possible causes of your engine overheating. For the meantime, as soon as you can start the vehicle after cooling down, drive the vehicle and try to turn off or minimize the loads , and avoid traffic sitting as possible, just enough time to reach home or a nearby service shop.
There are several things that need to be checked:
The coolant level and quality, and check for signs of coolant leaks.
The cooling fans,are they operating as designed? Check for fan blades damage or cracks.
The water pump could be faulty. Check also the engine belt.
The engine oil.
If the engine temperature sensor is faulty, it can also bring inaccurate signals and may affect operation of the cooling fans.
Check fuses and relays that power the cooling fans.

Fan doesn't run while in idle and begins to over heat until I start driving agin then it cools back down to normal. Also the fan runs when engine is off and drains the battery.


The fan is only supposed to come on when there is excess heat .. in normal driving conditions it doesn't start. When you start your car in the morning the fan won't come on because the engine is cold.

With a hot engine - and it depends how hot the engine is - the fan will only kick in to prevent overheating. In heavy slow moving traffic or a traffic jam, the fan will kick in if needed.

The air flow through the radiator is usually sufficient -in normal driving conditions - to cool the engine.

When you park up and the car has a hot engine, the fan will kick in. This is perfectly normal. It is caused by a surge of hot coolant triggering the fan sensor. Perfectly normal.

The fan then should cut out after a while .. maybe 2-3 minutes at the most. If the fan runs continuously that suggests a fault in the temperature sensor switch.

Next time - wait by the car and see how long it takes for the fan to quit after you have parked up. It should stop of its own accord after a couple of minutes.

If the fan cuts off after a short while, and your battery is becoming drained, that's probably a battery or alternator fault.

Remember: when you start the car the fan won't kick in at idle speed because the engine is COLD, and there is no reason for the fan to start up ..
The fan WILL kick in for a couple of minutes after you have parked the vehicle and the engine is hot

When idling my jeep overheats. The cooling fan is running and it speeds up when temperature goes up. The temperature gets close to 260 degrees and the engine tries to stall. when I start moving it cools...


At idling speed an engine does build up a lot of heat and the cooling fan will kick in. In slow moving traffic or traffic jams the temperature gauge can touch the red - particularly on hot days. The reason it cools down when you start moving is because of the air flow through the radiator.

Presumably there are no leaks from the cooling system otherwise you would have mentioned it. In normal circumstances the fan will not be running as you are driving at speed, as the air-flow through the radiator is sufficient to cool things. The fan only kicks in to get rid of excess heat - and this usually occurs at idling speed or after you have parked the car.

If the fan is running all the time as you drive, this points to either a fault in the fan switch, or the car is running too hot. presumably in normal driving the fan isn't running and the temperature gauge reads normal?

It is common - in stationary traffic many cars overheat (particularly big engined models) try to stall and 'cut out'. Restarting can be difficult until the engine cools down.

Is your car overheating in normal driving conditions or just at idle speed? Overheating in normal driving conditions can be caused by things like a failing water pump, blocked radiator, collapsed hose, faulty thermostat or, in the worst case scenario, cylinder head problems.

Overheating at idling speed is 'common'. Check your coolant level. If your car isn't using/losing coolant then there probably is no major problem. You can flush out the cooling system and refill with new coolant - and also check your radiator. Are the cooling fins crumbling with age? Or maybe they're partly clogged with insects and debris from the road? A blast with a hosepipe wil sort that out ..

The question is how much does your car overheat in normal driving? If it doesn't .. it appears as though you have nothing to worry about as such. Most cars have 2 speed fans... the 2nd faster stage kicks in at some point dependant on engine temperature. Perfectly normal.

Cooling fan runs even after motor turned off


This is perfectly natural for the fan to continue running when the motor is turned off. I have seen them run for up to 15 minutes depending on how hot the day and the engine are. If it is not cutting off at all then you may have a problem in your heat sensor.

1998 Cadillac DeVille Overheats


The cooling fans will not come on until 225 degrees. Normal temp is around 199-215. Sitting still in traffic most will inch up around 220 or so. When you turn ac on it turns the fans on and may cool down engine, Check fan operation.

Engine cuts off in traffic when car slows.


Sounds like it could be an ignition module breaking down.
