Post #1
Guys,I was sitting in traffic today and noticed that my Fan on my Rad is Kicking in rather late. I was very close to turning the car off!! and this was in the middle of London. The fan is kicking in just after 100c this seems way to late. IN the FAQ it says around 97c but my needles going over the 100 mark!! Is a sensor or switch need replacing, last thing i was is the HG blowing.  |

Its 97 degrees for the low speed fan, 107 for the high speed, if it comes on at 107 it will still be fine. Did the fans actually come on? If its not coming on just low speed its probably the brown temp sensor. ________________________________________ Cherry Red 306 HDIChampionship White Integra DC5 Type R |

Bennn, the fan did come on mate. The fan was on when th temp hit 107. If you look at the pic at the top, the fan was running at the time. Was bit close to the red! I think I going to get some after market gauges, as I want proper readings when I run the SC kit. |

Personnaly i wouldnt worry too much, sounds like they are working fine. ________________________________________ Cherry Red 306 HDIChampionship White Integra DC5 Type R |

If one fan is broken, you will not get any low speed operation and only one fan at high speed which may not be enough if we get a hot summer.________________________________________ S Reg Diablo standardsSpec SORNEDR Reg Nile standard spec written off then repaired X Reg Astor in need of TLC R Reg Nile to restore Set of Lions to fit. |

Bear in mind it's a Rallye so unless it had A/C fitted in the factory it won't use the brown sensor and it will only have one fan.The gauge reading is definitely above normal operating temperatures. The temperature gauges on Peugeot's of this age are actually very accurate assuming the sensors are in good working order. The gauge reading comes from the blue sensor on the thermostat housing and there is a green one that is used by the ECU. A/C cars also have a brown sensor for controlling the fans, but non-A/C cars use a switch in the radiator for the fans. The high / low speed switching is done in the same way as the A/C model, with the relays in the fan cowling switching the fan motors between parallel and series circuitry. On the Non-A/C configuration a resistor pack is used to provide the voltage drop needed for low speed operation. You can actually upgrade to the two fan setup just by removing this resistor pack and installing the fan instead. The temperature switch in the radiator is the first thing I'd look at, and check the relays in the fan cowling if the switch is okay. ________________________________________ Rich |

It wouldnt be a air lock in the system causing the High Temp would it Rich? |

It's a possibility if the coolant has recently been changed and the system hasn't been bled properly. ________________________________________ Team Nile 6 Team: 40.2 MPG  5 x a 306 owner! currently abusing type r's in a town near you ™  I truely live for the 306 ® Build date: 29th October 1997 Wednesday's car midweek madness  |

What condition is your rad in? it could be old and partialy blocked with bugs and road dirt, a new rad will help keep things cool.Plus you could wire in a switch and manually knock the fan on when u feel its getting warm. ________________________________________ My GTi6 track projectWhite Rallye project |

Its a 6, I will check the relays and test for a Lazy fan motor, I ordered some fan sensors today but dont think that they will fix the problem ________________________________________ stevenage black gti 6, 198bhp |

Just pop out to the car. Turn on the ignition and unplug the brown sensor and check the sensor. Its usually that or a shagged motor. Think dodgy relays are the rallyes fan issue. Could be wrong though. ________________________________________ See the sheer power and might of the lesser known burrowing owl. |
