Question about 2000 Jaguar S-Type

1 Answer

1999 S Type 4litre V8 2mths ago fan stays on after switching engine off. fan stops after 4mins. I gather this is normal under extreme conditions. this should not happen after a 2 mile trip. The radiator sensor and module have been changed but the fault remains. Please can you offer some advise? Thank you Ernest Roberts ernesteroberts@btinternet.com

If im not mistaken its a fail safe system its designed that way the fan will run until the engine cools down to a certain temperature i believe its around 150degrees yours may be a little different or it could be the signs of a early break down the sensor may be failing. hope this helps.

    your fan relay may be malfunctioning it could be sending a bad signal to the ecm causing your problem and its not unusual to get a faulty part you may have gotten a dud when you purchased your sensor.

My 1999 Montana van is having cooling problems what is the normal moter running temp


The PCM will complete the ground path for low speed cooling fan relay under any of the following conditions:
• When engine coolant temperature exceeds 105°C (221°F).
• When A/C is requested and ambient temperature is above 9°C (48°F).
• When A/C refrigerant pressure is greater than 190 psi (2 volts).
• When the ignition is Off and engine coolant temperature is greater than 140°C (140°F).
The PCM will complete the ground paths for all engine three cooling fan relays under any of the following conditions:
• When engine coolant temperature exceeds 113°C (235°F).
• When A/C refrigerant pressure is greater than 275 psi (2.9 volts).

Why did electric fans stop working?


Does the engine reach normal operating? How hot does the engine get in degrees F? The low speed may not come on till about 220 degrees F. The fans may come on, if you turn on the ac, under the proper conditions.
Check for applicable trouble codes, to check codes, yourself, at the least, you need an obd2 code reader. Some of the national brand auto stores will check codes for free, if there are any. Also, check coolant temp sensor. Don't replace anything unless your testing points in the direction. Check applicable fuses.
I'd check codes, first.

Why does the Airconditioner condenser and radiator fans stay on and run continuously without turning off on my 1999 honda accord whenever the a/c is turned on? This started happening after I had a front...


Sounds like a micro switch problem.
the relay is staying and saying on even when off. An electric program test should fix the problem. They are small diagnostic machines that plug into a socket either under the bonnet or in/near the glove box.

Hot air from AC vents. Sometimes the system is working ok though.


That is not a whole lot to go on. I would recommend gathering some more information like: WHEN and under WHAT CONDITIONS does it work? WHEN and under WHAT CONDITIONS does it NOT work? When it stops working, is the radiator cooling fan working properly? When it stops working is the A/C compressor clutch engaged and the compressor running? Will it start working again if you cycle the temperature control to HOT then back to COLD again? Will it start working again if you turn the A/C system off for a few seconds, then turn it back on?

All of these things can be clues to what is going on with your system. This information can be EXTREMELY helpful in pointing you in the correct direction to getting it fixed without wasting your money on a bunch of parts that don't fix the problem.

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

Fan on car stays on for a while after car has been turned off.


Hi:
The fan running after the car is off is a normal condition , if the temperature sensor is detecting the engine is still hot. You should continue to check out the cooling system to see where the leak is...First, check your coolant level when the engine is cold, then try to determine approx where the dripping is coming from, either the engine area or the radiator . This will help you determine what is wrong, and go from there. If the leak isn't substantial, a bottle of Radiator stop leak might be a good start.

Why does the heater blower stay on when the car is turned off and the keys removed its a bmw


are you talking about the fan blower inside the car or the fans under the bonnet..? the fans under the bonnet may stay on for a while after the engine is switched off to prevent heatsoak. This is when the engine actually heats up more after switch off due to latent heat within the engine. The fans will remain on until the coolant temperature has fallen and stabilised, then the fans will stop. If the blower fan inside the car keeps running, this may be a feature on the car to assist with heat soak but I would think this is more like a faulty power relay or fan controller if the car has climate control..In this case, my advice would be to consult a qualified autoelectrician.

Both fans, motor and A/C is not working properly.


hello yafrivera,

does your car's engine is straight to the radiator?. meaning does it has its mechanical fan attached to the water pump of the engine?

if that is the case, then the ac fan that you are reffering to is the auxilliary fan where in it is triggered by the high pressure switch.

that is just normal for that fan to run at 350 psi then turns off at below 200.

that only means that you are low on gas because the normal pressure of the condenser is 250 psi.

if you are under charged, the pressure drops below 200 and cuts the fan, as the fan stops, pressure again shoots to 350 and triggers the fan back on, and so on..

but if the charge is correct, as you turn it on the first time, the pressure shhots to 350, cuts the fan on, pressure drops to 250 at full charge then the fan would no longer stop.

i hope i was able to solve your problem...

pls rate me

tnx
