No I screwed up. I took the whole Mini apart and rebuilt it in my living room. Now I can not figure out how to get it out of there

Thanks for the compliment.

Actually it does not even get to be garaged. A car cover and driveway parking is all.

 

Thanks





I mounted the cooler and by-passed the OEM lines and reservoir. I installed a motorcycle reservoir to act as my both a reservoir and a way to add the fluid.
So far this seems to work? After thinking about what Kapps said I will be installing a line pressure and oil temperature gauge.

After Reading another thread having to do with Power Steering issues I will be installing a Fan control and by-passes the OEM plug into the Power steering Fan. This will allow bot fan speed control and temperature control to be set as needed.

Now this inexpensive project just turned $$

Sounds great. Adjustable temperature control is perfect for a project like this.

 

keep it going!!! i hope this is a fix . i for one really appreciate your efforts .

 

so you're going to splice into the feed to the stock fan? why not just run a seperate circuit with it's own controls (temp,speed) , where are you going to mount?

 

one other thing, i believe we're stuck keeping the stock fan . it cools the electric motor for the pump yeah? so even if we cool the fluid, which will no doubt add life to the pump, the motor willl still get unbelievably hot yeah?

 

hmmm, is the fan blowing directly onto the motor? I'm not sure exactly how it is being cooled. IMO, keeping the fan in current location defeats the purpose of this whole project. Cooling the fluid will likely extend the life and efficiency of the system, but it will not overt a complete failure of the PS motor caused by a fan failure. IMO, the fan part is what needs to be fixed.

 

it's all heat . and heat transfers . we can agree that the stock system is too small on volume for the temps . so fluid problem will be solved by he who loves red . but the stock fan seems to be a keeper. at least the location of it is maybe . but what of the manufacturer of the fan ? can we find a more durable fan? maybe the fan was a cost savings cheapo .

 

whaaaat..

I took the fan off and there seems to be a bit more room for air to get in there. Also I ran the fan on the bench. What a pathetic little fan. What was MINI thinking? I use a 650 cfm fan for my other projects and it is slightly larger then the oem Mini and blows twice the air? The mounting may be a challenge to get it in there but I may just leave a fan out of this project altogether? With the extra fluid capsity and the cooler the fan may be redundent? IDUNNO? Right now I am tring to figure how to get gauge sender in the line. I may have to hard line a small section?

 

can you measurethe motor with fan and without? it'd be great to can ot all together . but sitting in traffic i gotta wonder what would happen to the motor .

 

A fan that will not take a crap so easily and also blew much more air would definitely make a difference. IMO, if the stock fan stays, the project is a waste. You would making the system work better without getting rid of the major failure point. A better fan with a sensor that would notify of a failure would be the best bet IMO.

I would really like to get the actual fluid temps from the system. I wish I had some testing equipment!

 

The fan itself is in a vulnerable area to begin with? So IMO the fan is out of there. The type of cooler I am using does not require volumes of air to be efficient. I know the best fix for most is as you stated come up with a better fan. Connecting a 3 wire ground activated light in the circuit would show if the fan came on.I am not sure about if it failed how to wire that? As for a temperature gauge you can easily spice into the high pressure line with an 1/2 NPT tee with a 1/8
NPT to install a electrical sender for a temp gauge. Summit Racing has them.

 

I have looked everywhere and can not find the OEM specification for the pressure rating on the high-pressure hose? But I did find that the expansion capacity is 35ml. With a system under normal operation. This means that a larger reservoir is not needed and smaller can be substituted.

 

Up until now, I never realize people had problems with the P.S. in their MINIs. I'm @ 50k miles and so far never had any problems with it. *knock on wood*

I will say that it does make some noise when I turn it which sounds like a high-pitched whine. I never thought much of it though. Is that a problem?

 

No that's normal. If it stays the same high pitch and volume even when not turning, or it gets a lot louder, or it stays on after turning the car off, then it's a problem. My car has always made the high pitched noise pretty loud and it has done it since I got it 60k miles ago.

 

When I picked my car up in 02 the dealer was right there almost worried I would say something about the wine of the PS motor. I always liked it myself.

But then I ran around as a kid with playing cards on my spokes to.

And my street cars all had Pete Jackson Gear drives and I always ran a tight blower belt on the 671s.

Wine is Good Cab Sav's.

 

Nitro, hows this project coming along. I would not have seen this thread, but my PS quit last week and I am now finally getting around to fixing it. When I worked for the dealer, I replaced a bunch of pumps that had burned the positive terminal, the kind of electrical corrosion that occurs with a very high load on the wires. The pumps have a temp sensor for the motor temp, not fluid, and will shut off if the motor is working too hard. I do not think that cooling the fluid will help, but it would help to machine a heat sink for the motor. I just took my motor apart and removed a few teaspoons full of copper dust from the brushes and stator, blowing it out with compressed air. I hooked it back up, found a fault in the EHPS for a short circuit, cleared it and activated the pump on both 50% and 100% and it worked (for now).

Nitrominis was banned from NAM if I remember correctly

 

Yeah he's gone for good.

 

Pity, well I hope this can help someone anyway

While the reasons why we will be doing it are of a different purpose, we will probably be attempting to retrofit an R56 electric steering rack on our R53 race car this winter. This is obviously not a budget solution for your daily-driver. Details will be posted in this thread at some point:
