I need to replace the water pump possibly.

Power steering makes wering noise and goes hard due to more than like been very lowe on pwer steering fluid .

1.power steering pumps normal leak fluid in the commodores and need replacing.
2.steerings always leak.
3.Also check the hose that come from the p/steer resvoir and even p/steeer cooler hoses and the metal pipe that mounted at the front of the radiator these are all very common faults

do u have any power steering fluid in ur pump? This will cause it to steer hard and should also be making a high pitch whining noise. I believe u need a new power steering pump and if the hoses going to the pump are leaking, then you will need to replace them as well.

You can access the diagrams here. We however do not have them.

This sounds like the hydroboost unit is leaking.behind the master cylinderThe braking system on this using the power steering pump to provide power assisted brakes instead of a brake booster. The hydroboost unit most likely needs replaced.

All depends what is leaking. For power steering leaks there is not much to do but replace the leaking part. If it is a hose it is not a big deal. If it is the power steering pump itself check autozone, etc for availability. They'll probably have to order it in for you. Sometimes you luck out and the leak is due to a seal where a hose is screwed into the pump or the rack and pinion unit. I believe some auto parts places carry stop leak for power steering units but I have no experience with them. One last thought is if the car is pretty old and the leak a slow one, you just check your power steering fluid periodically because you can buy a whole lot of power steering fluid for the price you'll pay for a power steering pump. You can also consider a replacement from a junk yard. Generally power steering pumps out last the cars they are put in.

You probably lost the shaft bearing and seal in the pump. Replace the pump as it probably has damaged internal parts as well. Is this an engine driven fan or an electric one? If the engine tossed the belt during this event, it may have caused the fan to become damaged. If an electric fan, the shaft may be bent--replace the motor. If engine driven fan, you will need to disassemble it to find it's problem. Inspect the drive belt(s) for wear or damage. Recheck for proper cooling action after everything is back together.

either a tire seperating or unbalanced...
Bad waterpump...it has a weep hole that lets you know its time to change it.

It very possible that the new power steering pump is defective. I would take it back for a possible warranty issue.

I'm confused about the part where the water pump damaged the power steering pump. The power steering pump doesn't require any cooling from the water pump. The power steering pump only needs the belt to run it properly.

hi somewhere in the system it is sucking air check for signs of leaks on the rack,pump,and all connecting pipes if they look ok the favourite will be the steering power pump seals. its rare but the steering rack seals can be faulty yates210456
