So as its a GTi6 and completely different from my old rallye i've no idea.It has had the aircon ripped but still has both fans. Which one comes on when the car gets hot? Or is it both? Can I bin one and it'll make no difference? Which one? Without the pressure sensor on the aircon attached will they come on at all?! Thanks ________________________________________ Nothing to see here |

As you look at the engine, it's the right hand one i think. Single fan for different settings of speed. ________________________________________ Richies Project RallyeElectrical work carried out in Portsmouth jamiek_uk2000 wrote: - Top Tip!!!

Eh? Yes on the rallye the fan became faster, not sure if that happens on the GTi6 with aircon.So I can bin the drivers side one and open up that side of the cowling? ________________________________________ Nothing to see here |

There's a really good FAQ on the cooling fans. If I remember at low speed the fans are operating in series, so removing one would presumably disable the low speed running. I had a problem with a pair of fans where one wouldn't work at all and the other only at high speed. This suggests that removing one shouldn't be an issue. |

After looking at that if you bridge the left motor connection then it'll be fine.________________________________________ Nothing to see here |

the bit attached to the fan cowling, connects to the car loom with the round plug at the bottom. Being non aircon it'll have a three pin blue plug at the top for a two speed thermoswitch, but as its Turbo diesel its still twin fan, I might have one of these said looms. ________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

As said Adam, the fans run in series when the engine temp reaches 97c, then if the engine temp reaches 107c they run at full speed in parallel.If you have no air-con physically fitted, you can bridge the air-con pressure switch loom plug between pins 1 and 3 and then when you press the AC button on the dash it turns the fans on for you and becomes a manual fan switch which is handy.  ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone  |

Thanks Stan, that explains the bit of wire in that plug.Thing is I wanted to sack off one of the fans and half the cowling. Will talk to Mei about it further - would be good to simplify the system anyway. Cheers guys ________________________________________ Nothing to see here |

As I understand it, the air con compressor won't kick in if there's low pressure in the system (if all of the gas has escaped as in most 6's) and that this is a safety function to stop damage to compressor? If so, if the pins were bridged but the car still had the air con system installed, would the compressor be fooled into thinking there's refrigerant in the tubes and begin to pump? Or does the compressor have a built-in sensor to decide whether or not to function? |

Yes, you are correct Tom. Essentially, by bridging those pins you are telling the ECU that the AC has sufficient gas and to fire up when you press the AC button. If you make this mod on a car which still has the AC physically fitted, then the compressor WILL start, so it's essential that if this mod is to be done, then the system itself requires removal.That way, when you press the button, the ECU thinks the AC is working, when in actual fact the only part of the system which is working is the fan controls.  ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |

I had a '6 with the plug pins bridged and the AC button used to power the fans and the AC system was all still left there with no gas in the system. ________________________________________  |

The reason it is essential is because the gas in the system acts as a lubricant for the compressor as well. Therefore, if the compressor is being turned with no lubricant it will eventually seize. Therefore, it should be removed from the equation.The fact that the pressure switch is there in the first place is a safety device to protect the compressor in the event of a gas loss. By bridging out the switch, you are linking out the safety and therefore this is bad practise. ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |

Yes, you may well have found that the unit had indeed seized, however the vicious clutch could have broken instead allowing the compressor wheel to still spin with the aux belt. What did you do with the compressor in the end?________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |
