Just me driving in circles on a hot day

arados · 07-03-2018, 03:14 PM

Kinda felt like I was playing catch and release, lap after lap(no passing). Not many wanted to turn off so I ended pitting often for more room to "stretch".

Temp was in the mid to upper 90s and my powersteering fluid boiled over...any advice besides a larger cooler?

After a cooldown I sat in front of the bumper spraying water at the unit to help bring temps down.

The power steering. Only fill to the add line. Do not top it off. Then fold a shop rag up, and gum band it around the cap. I installed the Z1 power steering cooler, and haven't boiled the fluid yet. If I did. It hasn't left a mess.

Also the Stillen power steering cooler kit is another good choice. What fluid are you using on your track days? I recommend flushing as much of the old fluid out as you can as it is has broken down if you boiled over. I would use a different brand fluid as well.

I use Redline.

I have a case of oem power steering fluid that I use to top off. I suppose I'll switch to something more resilient.

Since I started using Motul Multi ATF my power steering system has not boiled over at the track knock on wood. I found that the Motul Multi ATF and Redline D6 ATF hold up very well to high temperatures.

I have to double check when I get home. But I think it's the power steering fluid.
