Default Power steering squeal fixed!!

So, i had taken my GR into the dealer 3 times to get the noise that the power steering makes when the car is warm. Other posts have documented it, the psssshsssssshh sound that becomes constant after the car is warm. Well, from info from other posts, seeing how close the power steering lines run next to the turbo/downpipe, and noticing that the Type RA and rally cars have a power steering cooler i deduced that the fluid must just becoming too hot. So i ordered a small 4 pass fluid cooler and some AN connections from summit racing. I used a PermaCool 4 pass cooler (part #1009). You can do the non-AN version, but i wanted the AN connections. I used Summit's brand Twist-Tite AN connectors and tubing. To attach the cooler to the radiator cross member i just picked up some small aluminum stock and ss hardware from Lowe's.

-Results-- After driving for a couple different trips there is no noticeable sound now! I am extremely happy that this fixed this problem because i was worried about the longevity of the power steering system with all that noise. The install was pretty simple too as long as you have a dremel.

I have the same ps noise with my 2008 STI. Do you mind posting some updates when you have accumulated some mileage after this mod? I would be interested in knowing if this indeed solved the problem permanently.

Just went for an hour long drive today in 90 degree temps and never heard any noise. Usually it only take 5-10 min of driving to start hearing the sound.

Had my track day today. It was 95 f outside. Never heard any power steering noise. I'm pretty happy.

I'm surprised not more people have posted. I thought this was a common problem with the '08s. If your car does have this sound i would recommend fixing it, because this sound is not normal for a power steering system to make and can cause premature bearing or pump failure.

ps - still no sound.

I haven't seen many threads about people's power steering failing just because it makes weird noises. It probably is normal, just like the hundreds of other weird sounds our cars make. Your fix is pretty creative though, but I don't see it being a necessary thing.
