Afternoon All, long time since i've been active on here, but I need some advice, simple as it may be however! I feel I may be about to make myself look like a right old moron . . . anyhow;

Dropped all the coolant and gave the system a flush, all back together again, filled up and wanting to bleed it. Already done my research on here as to different methods and such and opted for the "temp header tank" method. Got fluid from both other points (rad top and thermostat) bar the matrix point (valve cap). Tried and tried but just got coolant everywhere.

Attempted to bleed up using usual method --> let engine come up to temp, open points in order till fluid appears and seal off again. First attempt failed at the thermostat and I scolded my finger quite bad so gave up as I was in agony. Tried again today and couldn't get water from the rad, thermostat was fine, then the matrix point wouldn't spew anything either!! Confused. Huge air lock somewhere? Is it possible I've f**ked something up?

No heat in cabin either I noticed.

Btw, I attempted to use the overflow to blow through with the cap on but I could feel the air escaping, I think through the cap itself. I used a bleed pipe to blow through so the seal on the overflow was fine, not sure how this method can work, if someone would care to explain, please do?

Any help much appreciated.

I open all three, fill up, close as appropriate, that's before starting up, you will find that the rad will fill up first, then the thermostat housing, then the heater matrix.


I drill a 3mm hole in the top edge of the stat to aid bleeding as per peugeot sport build data.

you don't need to set the heating on hot, as there is no valve in the system like a fecking ford.

Never understood how people struggle with this

I fill rad through bleed point and rad cap until rad is full,fire up engine,bleed thermostat bleed point then rad,then remove matrix bleed point and hold the revs steady at a fast idle speed and replace the cap while coolant is flowing freely
Then check the heat coming out of heater in car,if ok just leave the car idling with rad cap off for a while,if no heat in car re-bleed matrix bleed point

I've been told that you shouldn't rev whilst bleeding as it can push air passed the bleed point.

If you do what welshpug has said with your temp expansion aslong as the water is higher than the bleed point it will work. If it doesn't something isn't right imo.

I have always done it this way as well with no issues.

Interesting discovery then. Will try this again later thanks.

Can anyone confirm roughly what temp the stat opens please, as I've had nothing flowing at about 85.

Welshpug is there a different stat for the 6 that will bring the cooling fans in at say 90oC as apposed to 97oC?

thermostat does not control the fans, the fan thermoswitch (non ac setup) or the brown bitron sensor and the bitron control box (ac setup) sorts all that.

I've never found them to be an issue, the fans keep them cool enough when they need to, never found the fan to come on that quickly with my engine at all

(same rad, single 150w fan not a 250w, single fan cowling not a twin fan like the rallye with one missing, same engine)


Thermostat opens at 83 degrees, so it shouldn't be running any hotter than that until you sit stationary.

when did it last have a rad, water pump, thermostat?

Don't forget the 306 has a 'live' gauge whereas most cars don't.

With this type of gauge, you see every single temp change (which I like) but with other cars the gauge will just sit at normal for example and despite the temp rising and falling all the time, unless it rises way too much due to an issue, the gauge will not show movement.

Hmm, interesting. I've always thought it heats up quickly, during this time of year I would say around 5mins of standing/crawling traffic and the fans kick-in, though it has always been this way under my ownership (5yrs).

The GF's 307 can sit for ages without the heat barely rising, similar in my brothers Mk7 astra, mums E46 328 etc.
