I remember reading about your issues but didn't know that this was the cause. Any idea why this was not an problem with the original box, or did you go from manual to PS? I luckily got a cooler from Bergman but will certainly look out for similar symptoms.
I had manual steering before. Also forgot to mention first PS Pump stopped working and Bergman gave me another new one. Not sure if heat killed the first pump or not? So had a few challenges struggles but well worth the effort .
