There's usually at least two bleed points. A Haynes manual is good for finding their locations.

I checked the Pug forums and the last time this happened to a 207 owner, it was a problem with the water pump.

Just for this problem I bought Haynes Manual. I could not find even the info about bleeding points.

Since about the millennium car makers have made it increasingly difficult for owners to DiY, providing less and less info in the car's handbook, and fitting black plastic lids over everything. Perhaps as a consequence Haynes have offered less info in fear of people invalidating warranties?

I presume your 207 is a petrol? If the coolant has not been changed recently I can't see any reason for an airlock, and Peugeot coolant is not normally changed unless it discolours.

I have updated that forum with a picture. I have started to worry it might be HGF because of the white dots in the water tank.

I still dont know where the bleeding points are.

If I new, I was going to open the all bleeding points and tank cap, so it might relase the air if it was the airlock issue.

Am I on the right direction though?
