I always fill the rad up then start the car and bleed it whilst it's running using the three points.I've never made a header tank for doing this on these engines, yours should be fine but I personally wouldn't have done it the way you did. ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone  |

Hmm was following the FAQ...Also, the coolant was absolutely crystal clear, apart from the bolt in the heater matrix bleed point was covered in oil/black liquid. The bucket of coolant which drained out looked normal though. I'll borrow another car to go to work tomorrow and check to see if it bled properly tomorrow afternoon. The header tank was working fine until it suddenly spat 110 degree fluid everywhere! Glad it didn't get me in the face, wasn't far off! ________________________________________ 61k miles Ph.1 Diablo '6 Project Thread |

Car didn't want to start from cold at all yesterday, took ages to get going, but when hot it started no problem.Going to attempt to re-bleed the cooling system to see if that helps. Strange that it was fine since replacing the sensor and bleeding the system up until now. ________________________________________ 61k miles Ph.1 Diablo '6 Project Thread |

Re-bled it. When the thermostat opens (I assume), the coolant level rose like last time and began overflowing out of the rad so I quickly got the cap on. I'm really not sure this is normal? I'd have expected it to go down if anything when it began circulating...________________________________________ 61k miles Ph.1 Diablo '6 Project Thread |

Bleeding the system properly appears to have stopped upsetting the new CTS. Thank you everyone.________________________________________ 61k miles Ph.1 Diablo '6 Project Thread |

The car is extremely reluctant to start from cold again. Not always, only sometimes, and only when cold. It has been fine for a while since replacing the CTS and bleeding the coolant system properly....any ideas?________________________________________ 61k miles Ph.1 Diablo '6 Project Thread |

As I have been fearing...the car runs flawlessly though.I know a few members do HG replacements...anyone willing to travel to Oxford and do one if this is the case? Are there any checks I can do? No bubbling in coolant at idle, no mayo around oil filler or rad cap, car has been having difficulty cold starting for a fair while without having total HG failure... Not sure what to do tbh. ________________________________________ 61k miles Ph.1 Diablo '6 Project Thread |

Actually thinking about it, when the car got up to temperature and I assume the thermostat opened, there were A LOT of bubbles coming through and the coolant was rising very fast, could this be an indicator that combustion gases are getting into the coolant?________________________________________ 61k miles Ph.1 Diablo '6 Project Thread |

try your fuel pump. mine had exactly the same problem. reluctance to start etc but once going it seemed to run generally fine (sometimes cut out under breaking and had to cure with ecu reset under electrical load). boshed in another one with good pressure and everythign was A-OK. idles dead on, not even the slightest hint of random tiny hunting i had before. bit pricey new but worth it. ________________________________________ the world is changed by people in sheds |

and my theory on why so... low fuel pressure will cause a poor spray pattern. the fuel is not properly atomised because of this. on cold starts there is no internal engine heat to boil this into a finer atomised mist. hence trouble startingbut once the engine is warm. on starts the heat of the engine inside the combustion chamber masks the low fuel pressure problem by alowing the fuel to atmoise properly. ________________________________________ the world is changed by people in sheds |

Haven't had the chance to check plugs yet, coilpack bolts were rounded off by whoever last serviced it.They are M6 capheads, anyone happen to know the length to save me pulling one out so that I can buy a set of good ones? ________________________________________ 61k miles Ph.1 Diablo '6 Project Thread |

Changed the plugs for new NGK ones. The car ran fine with the new plugs but was slightly high idle (just over 1000rpm instead of 950ish) and still had a bit of difficulty starting from cold.Here is a picture of the old plugs. I have used the car fairly regularly for a year, but before that it was only used in summers and these plugs were what were in there so that may affect the colouring? Please me what you think. Could this be the HG? Tomorrow I might check the ICV with a multimeter, I did clean it a while back with no issues but it is worth a check.

Those plugs look a lovely colour to me. The threads are a bit oily by the looks of it, but the actual colour of the plug says good to me.  ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |

Thank you for your input.Any ideas as to what the problem might be? Anything other than the ICV to check? Seems like the most likely thing given that it seems to struggle for air on start and throttle helps it choke into life, and it occasionally idles ever so slightly rough all of a sudden. CTS fixed the issue for a short while so maybe both CTS and ICV were going funny... ________________________________________ 61k miles Ph.1 Diablo '6 Project Thread |

Also...testing the ICV with a multimeter...test both pins of the connector? Not sure exactly where to test, bit clueless about electronics.________________________________________ 61k miles Ph.1 Diablo '6 Project Thread |
