ML55 Power steering bleeding

[antml55]

Hi,
I am having a problem bleeding the power steering.I found some instructions
which i have followed.Wheels off the ground lock to lock 30 times etc.

High pressure is building up in the return pipe and tries to blow off the pipe where it connects to the oil cooler in the radiator.I am not sure why this is happen as i am thinking that the fluid should be passing through the cooler and back into the reservoir and not backing up.All i can think is that there is still air
in the system..

It has been a real pain.

Any thoughts please.

Did you manage to get to the bottom of this?

I have managed to find the problem.My first thoughts were oil cooler in the radiator because
when i blew air through it felt slightly restricted.What was causing the restriction i don't know.

I ended up purchasing a new radiator and the problem has been solved.
