Author Topic:   Powersteering problem??
posted February 21, 2004 07:17 PM
The powersteering isn't working properly.

It is a brand new krc pump that appears to be pumping enough fluid.

The tank was a little low on fluid and seemed to work at first, but now it isn't.

We thought maybe the steering box had messed up... changed that and same problem.

Can the whole system have air in it? Is there a way to bleed it out?

Fire up your car, turn the wheel, and watch your return line it may be collapsing, restrickting fluid flow, and if it doesnt, bring the rpm's up and do it. It happend to me once. Its worth a try ???????

I've got a new KRC also,it does'nt work very well either.Talked to some other guys that have the same problems.I'm not impressed with their products{nascar uses these pumps }they loose their powersteering too.

Jack the frontend up where your front tires just clear the floor this will make it easier to turn and steer frontend back and forth lock to lock several times this should take care of air works for me....sounds like youve got other problems ...good luck.....Towman

Thanks guys... I did notice the return line collapsing a little, but since it was low pressure line... I didn't really think it was the cause.

I may have to investigate that further.

I will also try the bleeding part as well.

Measure your pullies and call KRC, we had one and just replaced it with the KRC. We were spinning the thing to fast and it was causing the pump to cavitate.

we had to open up the outlet fitting with a small drill,you can also buy different sizes to adjust output from pump.they are a restrictor in effect to taylor to your feel.

So do you think it is possible that it is pumping TOO much fluid?

While the motor is can open the cannister and look in and it has a very steady stream of fluid flowing through it with a fair amount of pressure.

With the wheels off the ground... it steers pretty easily by one hand, but when weight is on the wheels it is very tough to turn and requires both hands with much effort.

It does get slightly easier with higher rpm's as opposed to idle, but not much.

It may be more simple than you think, Are you running a good power steering fluid? Alot of people use transmission fluid and that will break down over time. Just a thought.

It is actually brand new... Royal Purple fluid. So I don't think it is that.

I still have to check out a few of th suggestions listed above.

i hope yall figure this out i have three , two sweet and one stock s-10 all doing the same i took them off throwed them in the corner and put a stock camaro pump on it ran it all season with no problems would like to run the lighter pumps when you figure it out i even took the quick steer off and ran all year without it and yes i use powersteering fluid not trans fluid tried turning lock to lock works for awhile till you get to the track

When you say... Cavitating... Just exactly what does that mean?

Sal, that would be a tough one to figure.....

The total area of the face of the impeller will be different for different water pumps and would require taking them apart to measure them. The clearance checking of the impeller would also have to be done....not to mention the angle and design would have to be taken into consideration when getting these numbers.... It would be a pretty tough one to figure...
