power steering fluid
Afternoon all
Is it normal for power steering fluid to get VERY hot when driving hard for a bit?
I have a 95 wrx and have just changed a leaking res and pump. I have filled it over full with fluid but the pump still whines when the fluid gets too hot after a hard run. I have to slow down for a bit for it to cool and then the whine goes. Ive tried adding more fluid but it does not help.
Is there a better quality fluid i can use (currently STP) which perhaps works as well even when hot or do you think i have a problem somewhere causing the over heating?
Would really appriciate some help
