Then you should keep it blown out as maintenance.


my first C5 Zo6 had heat problems when i first bought it used. looked in radiator area found it full of tumbleweeds FULL! amazing it ran as cool as it did !

So yeah everyone check radiator when they first get a Vette!!

Any helpful hints with regards to power steering? I'm running a 305 square Pirelli take off set, and about mid way through each 35 second run I'm getting fading from the power steering. It'll come back after a few minutes of waiting for the next run, and then sure enough it's gone half way through the next run again. Suggestions?

Put in Redline synthetic oil.

If it doesn't have a cooler, put a Z06 cooler on it. If it has a cooler, clean the outside fins.

Have the pump revalved for $100 from PSC.http://www.pscmotorsports.com/

Thanks! I'm pretty sure the power steering fluid was synthetic already, but I'll drain and try something different. Just going to be a couple months before I take it out to another event, and if I had to do something like pull and send out the pump to have it re worked, this would be a fantastic time to do it. I drive the car pretty hard, and I know the pump was suffering. Just don't want to rely on the simple thing of fluid before next event unless it's supposed to pretty much definitely take care of the issue. I have a C5 Z, so that should have a cooler already right?

Yes, I would clean the coolers fins.

with all above. you have no idea how good Redline is, it is magic! make sure you flush the power steering system before you change it,

flush it every season!

and I am pretty sure you need a new power steering pump. might as well get the new one re valved too!

one more tip that really works wonders is to move the reservoir away from the engine. that really helps keep fluid cooler

Driving hard on the track during hot ambient temps will drive a corvette owner nuts. At least it did for me until I put in a Setrab oil cooler. Easy to install and there was room in the engine bay of my C6. With temps over 100 F at Thunderhill it works for me.

What's the reason for the revalve? What does it change? Feel or what?

I never noticed a change in feel, I did notice a change in the heat in generated.

At really low speed it made the car slightly harder to turn, more noticeable when cold out.

Hey man, little guy from the future here (8 years after original post, wow). This post has been incredibly useful for me. I have just started HPDE and have used this thread as a guide. I have started by doing as much reliability mods as I can affoard (RD radiator, DRM trans and diff coolers), and some comfort mods (track seat), then seat time (two sessions every monday and every track day in the weekends).

My next mods will be anything I can do to reduce ongoing costs (tire wear, brake cooling).

Regardless, thank you for writing this.

My track day friend has a C5 coupe - mine from the same year is an FRC. He mentioned to me that he boiled his PS fluid and had to pay to have a PS cooler installed - then proceeded to show me that the FRC comes with one - which at the time I did not know....

I'm headed to a track day on Sat - mostly stock FRC (headers, flip-tie mod, ECS tune, Hawk pads/Centric slotted/cryo-treated rotors/braided brake lines) - I noticed last time that the brake fluid reservior was pretty hot after a run - I searched for cooling tips but couldn't find any - what about soaking a towel in ice water then just wrapping it around the reservoir?

flush the power steering system and replace it with redline power steering fluid. Another cheap permanent fix is to move the reservoir away from the engine. Also you can add a bottle of Lucas oil, but if you drive in the snow etc it might freeze up lol I am in AZ don't have that problem

What he said, redline, also if the rack has never been rebuilt, may be tine.

Even though this thread is older than one of my kids - I just CAN'T stop reading it !!
I have nothing to contribute nor would I pretend to. But to those that did - Especially Zenak..... You get a Big Fat 'Atta-Boy' !!
I would think the OP either ended up with Carpal Tunnel Syndrome or Forearms like PopEye. Lot-O-Work got done here - THANK YOU!
