De-air the cooling system on the peugeot 308 1.6 HDI

I will tell you how to de-air the cooling system in the Peugeot 308 T9 engine. Everything is detailed, everything is point-by-point.

Have you done a video on how to properly drain the coolant? I’d like to refresh all my coolant as it’s 7 years old now

[@peugeoton4033]

I did this procedure a few weeks ago. I think 1 or 2 months and there will be a video. Unfortunately, there is very little time for installation so far. But there will be a video.

Hey i need help i am on a trip. I have changed the tank but did not the air. All 200 Km my coolant is completely empty but when opening the cap it comes back. Is it because of the air?

[@peugeoton4033]

With a huge degree of probability, this is the air in the system....it is possible that gases from the EGR heat exchanger.....gases from a crack in the cylinder are also possible....If the level just drops a little, but then it comes back on its own (after some time), then this is still half the trouble (I myself have been driving like this for more than three years). But if the level decreases critically (the tank is empty), then you can boil while driving and ruin the engine!!!

About the de-airing of the system....even if you didn't blow it up according to the instructions, it will blow itself up after a while

[@neo-pp1nx]

Have you already solved water loss?

[@peugeoton4033]

Not the loss of coolant, but the level change is important because the system is sealed. I am currently in the active phase of the solution.
