A new fan is needed. It's been turning for 16 years. Time to replace it. Same for the power steering. Depending on where the leak is, if from a hose, a clamp may need tightening. If from the pump, then it's time to replace.
power steering has pressurized hoses they need to be replaced with power steering hoses,if its the reservoir i suggest getting used from scrap yard, and your fan motor is dying you will soon lose high speed to for changing these products i suggest getting a manual like chiltons, from canadian tire or most auto parts dealers
Lingo is o.k., but I think you may be confusing power steering with power brakes. Power steering has no master cylinder (brakes do) and no power booster (brakes do). The power steering pump is mounted on the front of engine and run by the fan belt or the serpentine belt. The p/s hoses are 2- a pressure line and a return line, and run from the pump to the steering box or to the rack and pinion steering gear. It just sounds like you have a brake fluid leak at the master cylinder. If it is, you need a new or rebuilt brake master cylinder. Good luck. Post back for more.
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.
Yes this vehicle's fan is hydraulic driven by the power steering pump...to test the fan you may unplug the fan switch on the power steering pump or by unplugging the temp sensor(below the alternator). Rev the engine to 2500rpm and the fan should spin harder. If this does not happen, have the filter and lines for the fan and power steering checked. hopefully this helps...please rate...thanks
The cooling fan on the LS-V8 is hydraulic yes. But it also has a pressure switch on the pump that drives the fan. It is controlled by the temperature sensor. All these things must be taken into account. But the whining sound my lead me to believe that the pump is either low on fluid or is wearing out. The fluid the fan pump uses is the same as the power steering pump container so check it first. The same thing happened to my wife's Lincoln. I replaced the fan as well because everybody told me to do that but it didn't work. I found out that the fan is just a hydraulic motor in reverse it only spins as fast as the pump makes it spin and that is controlled by the temp. sensors. When the engine get's hotter the pressure goes up and the fan spins faster. This adds more power to the engine when it's running cooler because the fan doesn't have to spin at max speed. So good luck. I hope this has solved your problem.
It sounds like your power steering pump, not the belt. Have u checked the fluid level? If it's low it can make a 'growling' type noise. Any leaks under the car from power steering? U can check by putting a big piece of cardboard under the car at night, check where any leaks show up on it the next morning. ålso check the belt for fraying or cracks (if u find any, replace it), also the belt tension, if it's loose, the belt may squeal (not what u describe),
yes , i am sure you checked for leaks on the rack at the boots on both ends near the wheels. if none try adding a power steering conditioner to the pump . drain the fliud from the reservoir first by taking off one of the hoses the more conditioner the better. this may not work but it is an easy and cheap way first. there is also a relief valve in many pumps that might be stuck not allowing pressure to build.
