Hello

There are 2 bleeder screws on the circuit

The upper one is located behind the air filter and the lower one is under the air intake. To remove it, first remove the one from the turbo to access it and then temporarily put the one from the turbo back in place to avoid having liquid in the turbo because when the bleeder is open it can squirt (be careful to do it with a cold engine otherwise risk of burns)

Hello

After this time and therefore the experience of not having purged, is it still the same response?

Just empty and refill?

Thank you ☺️

Hello, according to the RTA this is the official method. It also confused me at first. Don't forget to open the heating fully to purge it.

Even though there is no bleeder screw, shouldn't there be a way to bleed the system to remove the air that got in during the oil change?
