Please take a look tell me what you think any tips ? ? ?Bleeding Engine switched off ! 1. Fit header tank bottle. Kept coolant at all times above the matrix screw. 2. First off top rad screw allow to p*ss out closed off once no Air . 3. Next up stat screw/5mm hex closed once no Air. 4. Final Matrix screw closed once no Air. Fire up engine and allow to reach 85-90c. 5. Repeat step 2. 6. Repeat step 3. 7. Remove matrix screw, fast idle for a while just to make sure no Air then close. While still running pull off the header tank catch the coolant, open drain screw and drain to half way down the expansion tank fit cap. |

yeah is a bit of a bummer when a fault is illusive. The way i see it is - if there was enough pressure in your coolant system to pop the heater matrix there is only gonna be one place where that pressure is going to be delivered to the system - and thats from a piston.Your bleeding method looks very thorough so i cant see a problem there. Only thing i can think of is if the engine overheated this may have caused it  might be worth replacing the brown sensor on the thermostat housing if your fans didnt kick in because thats the sensor for them. ________________________________________ Team Peugeot Sport 308 Gti�Black T'99 Gti - may she rest in peace - written off in a shunt on the A329m |

Indeed, check the sensor for the fans. Did you also have interior fans set to hot and on max? I dont know if its usual practic but that its something I was also told to do. ________________________________________ See the sheer power and might of the lesser known burrowing owl. |

The Fans were sorted roughly 6 months ago not had a problem with them since. The matrix was done about 5 months a go, its been through different stages first up was the matrix sorted that since then It was loosing coolant slowly over the week and the last couple weeks back it started loosing around 3-5 litres a day but could not find a leak it was as if it was only losing it when driving and once stopped no signs of a leak replaced the rad sorted that now it's the pressure in the system. |

Have been doing that not seen anywhere that this is needed on the 306 model but remember having to do this on my 106 so did this anyway but not on full speed I'll do it on full speed today. |

Its such a bummer, I do believe its properly the HG but just don't want to spend 500 odd quid with no other signs of it failing .Since the matrix blew I've done around 5k mile so would have thought this would of been enough to show up other signs of it failing ? |

nope, AdamB did several thousand miles before his went big stylee.no need to do anything with the interior heater controls on a pug, they have no connection to the flow of coolant through the matrix. that's only applicable to fords and renfaults. ________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

If it was losing 3-5 litres a day with a leaking rad, my guess is it has run too hot at some point during this time and popped the HG.________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |

That will be right the temp would not go over 80c it was just sitting on 79c for ages and ages until I turn them off. I remember being told to have the heaters blowing on my 106 wrong info then. |

Possibly although was only doing 20-30 min trips, toping the system up after most trips even bleeding it at times. Never had it gone above 100c at any time, well going by the gauge. Been keeping 15 liters of coolant/ bleeding kit in the boot for a month now  Bled the system today not much air really, mostly form the rad. Although did get a few bubbles up through the header tank when giving it a couple of revs at 85 -90c. Just hope theres no pressure this week when checking if there is I'll pick up a comp tester or sort it out for next weekend. |

Bubbles in the header tank when blipping the revs is a very common sign of HG failure unfortunately.________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |

It depends on whether or not the gasket has failed going fully into a cylinder, and therefore pressure from the cylinder is being lost. It is a good start though, and will also will also give you an indication of how well the engine is generally.Stan. ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |

The results are not overly good. I know you are trying to prolong this issue and hoping its an easy fix. Unfortunately, I would put money on the fact the HG is gone. I have been around the mechanics of these cars for the last 8 years, and I have seen this fault so many times I've lost count mate.________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |

I still think hg. Especially as there is now air in the header tank. You could still run it and see if more symptoms arise. But... If it is that, I'd defo get it done. Your motor looks too clean to right off.  ________________________________________ See the sheer power and might of the lesser known burrowing owl. |
