Servo Oil Temperature: How Hot Can It Get?

I found it amusing that the T5 has an extra ribbed servo cable running in front of all the other three coolers (LLK, AC, water).

Now I've seen that the pipe connecting the storage container to the pump in the G3 is also referred to as a "cooling pipe."

As it is currently positioned (in the slipstream of the engine carrier), it won't be able to cool very effectively!

How hot does the liquid inside actually get?

Okay, here's the translation:

Thank you.

Hello Martin,

Yes, I also noticed at the junkyard that many cars have a loop in the metal pipe in the front area, especially smaller Japanese cars had this (I was looking for a piece of servo hose ). It seems to be a normal solution. My Saab didn't have it, and the power steering has already been running for 420,000 km without an oil change...

"In the rear of the T3 VW bus, the sauce gets so hot that you can still touch the hose carefully, although I don't know what it's like at the front or what it looks like when driving at full speed. In the original design, there are also metal pipes there, perhaps for cost reasons."

hello
Carsten.

Das Problem ist nicht der normale Fahrbetrieb, sondern die außergewöhnliche Bedienung durch den Fahrer, wenn er die Lenkung voll einschlägt und in dieser Stellung festhält. Dann wird das Öl gekocht, da die Pumpe laufend Leistung bringen muss.

Da macht schon es Sinn, etwas Kühlung zu haben.

@Uwe:

Dazu passt auch der Warnhinweis im (G IV-) Handbuch, dass der Volleinschlag auf max. 15s zu begrenzen ist, um die Pumpe nicht zu überlasten.

Mein Golf II (MKB PF) zischte am Lenkradanschlag ganz theatralisch, so daß ich ihm das höchstens 2 Sekunden zumuten mochte. Mein Octavia macht das nicht. Und hat auch ein Kühlrohr. Ob das allerdings zur Servolenkung gehört, dazu fehlte mir die Muße, das herauszufinden.
