Power Steering Cooler - Where does it go??

[Negative Boost]

G'day. After searching through the tsrm i couldn't find anything that told me where the power steering cooler was situated. Does the cooler go on the pressure line, straight from the pump to the rack. Or in the return line, from the rack to the resivior.

Car in question is an MA61 with a 7M conversion. And i ask this as i'm about to put in a small factory oil cooler into the powersteering system. I havn't been running a PS cooler (no, not even that stupid hard pipe) since the conversion. So where's the best location?

Cheers

Fit it in the return line and if possible mount it in front of the Rad/ Air con condensor.

Shouldn't be to hard with a few hose clamps and a bit of hose just break into the return line somewhere.

Thanks mate. I'm placing it behind the grill inbetween the fog lights, so it should get plenty of airflow there.

Sounds like a plan to me.

Is a cooler upgrade necessary for street use?

Mine has the hard pipe plumbed up, seems ok so far...

[Robbos_Toyotas]

i put mine in behind the drivers side vent down the bottom of the bumper bar - is a TS magna tranny cooler and works a treat

Is fat camber, R33 brakes and a 7M conversion necessary for street use? Not really...

I'm more going for overkill than anything plus with the intercooler wedged in behind the front bar, getting that hard pipe in there would be a pain the buttocks! Moving it to behind the grill with this small oil cooler i have, it gets direct airflow and will be fairly easy to remove if needs be. I would also like to do a few track days if possible in the future so im trying to set the car up for track-based work.

Put it in the return line.

I vote like that (bottom right in the pic near the IC pipe on that side). Tis a MA70 oil cooler.

Heat kills power steering racks, and believe me your P/S fluid gets well hot with a bit of spirited driving. A hundred bucks spent on an oil cooler install can prevent a $600 rack rebuild down the track.

what does the heat damage specifically? seals?

Thanks for the input wilbo. I did get a MA70 oil cooler for the job but recently got given (thanks Psylent Knight) a slighty smaller oil cooler with outlets that better suit where i intend to put it, behind the grill. I'll post a picture up of the oil cooler and how i mount it tommorow if i get around to it.

If you run a p/s box then a finned cooler is needed if theres a turbo near it , with a rack the hard pipe cooler is fine unless the ex pipe is very close to it .

Its a rack but the dump pipe does run near it from memory. I'm mainly doing this becuase i do love a bit of spirited driving and want to do track work and as Norbie stated heat kills PS racks. Better to go overboard than to say, ah she'll be right.

Yes indeed, I had two racks spit out end seals after a trip to Qld Raceway (this was before I had a turbo engine by the way). Since installing a cooler I've had no such problems.

This is the 5 row MA70 Oil cooler on top
And the 3 row MX13/23 cooler on the bottom.

And this is where i'm going to put it, on the right. The MA70 one on the left is an oil cooler plumbed in factory style to the 7M. Then behind all that you can see the top of the intercooler.
