Volvo s70 fan runs after engine is off

Could be, but you will need to check for trouble codes, since the engine light came on. The code or codes may help you troubleshoot it.

check the heat sensor on the radiator

It sounds like the memory's low voltage supply is cut off.

Get the car Scanned and that will lead you to your faults.

There have been a lot of problems with the compressor cutting out when it gets hot. When the A/C begins to blow warm, check the power supply wire to the compressor. If there is power in the wire, you will most likely have to replace the compressor. If there is no power, you will have to trace it back to see what the problem is (a wiring diagram will help greatly).

Have the car checked to see if it has a speed sensor it could be giving you a bad reading.

It sounds like your cooling fans are not working.Need to check the cooling fan fuses,and the cooling fan relays.There is also a high side switch mounted somewhere on the high side of the ac system that cuts the fans on,or kicks them up on high speed when the ac system gets to high on the high side of the system.This switch may also cut the compressor off.I would check the fuses and relays for these fans first,this is more likely the problem.Is the car running normal temperature? If not the fans may not be running at all.Have them checked.The fan or fans may be bad them selfs.If I can be any more help,let me know.>>[email protected]

I would guess that the fuel filter needs to be changed. Replacing it should fix it. Excellent cars.

Locate the MAS sensor right next to the air filter box remove it and clean it very careful, check for any damage.

Hey Lindypop,

If you have another ignition key, I would suggest trying that key and see if the problem persists. The key has a micro-chip in them that allows the key to work in your vehicle only, and you may be having a problem with one of your keys.

If this is the case, a fault will be stored in the engine computer. It will be a good idea to check those codes and address them as necessary, it may help to avoid getting stranded.

Good Luck!
