The power steering pump in my car is whining and is using fluid, though it is not leaking on the ground. In addition, the car is hard to steer and is smoking.
Hello. If the system is losing fluid then there must be a leak somewhere. Most of the time the leak is at the rack and pinion so it tends to leak further back on the vehicle. If the pump only whines when it is low then that is common. If it whines when it is full also then it may need to be replaced. If the leak cannot be found I typically add dye to the fluid and allow it to identify where the leak it when using a UV light. If you need to have this inspected, consider YourMechanic, as a certified mechanic can come to your home or office to find the leak and repair the problem.

If you notice a squealing or whining noise whenever the wheels turn, there is a strong possibility that it is due to low power steering fluid. The power steering system uses a pump so the fluid can flow for smooth steering.
Causes of a Power Steering Fluid Leak
Worn seal on power steering pump. Cracked, perished or loose power steering fluid hose. Excessive pressure in power steering system caused by an overfilled reservoir, which could result in blown seals. Wear and tear in power steering rack, particularly the shaft ends and seals.
If there is a lack of fluid in your power steering system the fluid reservoir will get low. Your power steering pump draws fluid in from that reservoir and if there is a low fluid level it can also draw air in along with it causing the same bubbles and whining sound.
Most of the time, this type of noise is associated with a problem with the pump`s power steering fluid. In some cases, it may not have enough fluid to operate noiselessly. Check the fluid reservoir (usually located near the top of the pump) to make sure it`s filled to the indicator line.
Age and constant usage are the two biggest contributing factors to a power steering fluid leak. As the supply and pressure hoses start to age, they may develop holes through which the fluid can leak. Likewise, the O-rings and seals gradually lose their flexibility as your mileage increases.
If your car makes a whining noise when you turn the wheel, there may be a leak in the power steering pump. Or, the power steering fluid level may be low. Power steering making noise is something all motorists want to avoid.
If the power steering pump pulley starts to fail or intermittently binds, you might notice that your car`s steering will either not respond well when you turn the wheel, or it will respond excessively. When the pulley binds for longer periods of time, you may notice a burnt smell under the hood of the car.
A sure sign of air in the system is what sounds like a mildly disgruntled cat under the hood. This growling will get louder during power steering-intensive movements such as parallel parking. The first thing to check when the power steering starts moaning and groaning is the fluid level.
If there is air entrained in the power steering pump fluid, it can cause the pump to whine while it is running.
Power steering fluid is as vital to safe driving as oil is to continued engine prowess. Without this vital fluid, your power steering will fail. For example, if you have a power steering leak, you may not be able to turn the car with the force needed. This can lead to unsafe driving situations and a potential accident.
STP® Power Steering Fluid + Stop Leak is scientifically engineered to reduce fluid loss caused by seals that leak due to wear or shrinkage.
Faulty power steering pumps often cause fluid to leak between the reservoir and the pump itself. However, remember that not all leaks can be associated with a faulty power steering pump. That`s why a thorough inspection should be done to determine the issue.
Additives in power steering stop leak fluids work to remove debris, neutralize acidity, and fill leaks. However, they are not a permanent solution to fixing a leak in your power steering. Over time, a leak can start again, and you`ll have to add the fluid again.
Trapped Air In The Power Steering Fluid Or Pump
It`s possible the whining noise is simply coming from trapped air bubbles in your power steering fluid. If you suspect this is the case, you can confirm it by removing the cap from the power steering fluid reservoir and checking if any bubbles or froth has formed in it.
Leaks commonly occur at junctions where a rubber hose transitions to a hard line or where a hard line screws into the rack or pump. If you find a leak at a connection, you can have your mechanic tighten the connection; if you have a soft hose that`s leaking, it`s best to replace that hose.
How long does it take to start working? Bar`s Leaks starts working the minute you install and start driving the vehicle. You will usually see results in about 200 miles or three (3) days of driving.
Vehicles that are designed with a power steering pump should only be used when the power steering is operational. When the power steering stops working, you should refrain from operating the vehicle until the pump is replaced.
One of the main symptoms the power steering hose is going bad or is failing is the steering wheel becomes difficult to turn. If there is not enough pressure in the system to get the power steering fluid to the rack, the vehicle will be difficult to turn or make maneuvers that would normally be no problem.
If air does find its way inside of the power steering assembly, you may hear a growling noise when you drive and the steering wheel may be slightly harder to turn than it normally is. Bleeding the power steering is a simple way to force trapped air out of your power steering pump and hydraulic lines.
While the transmission is the most likely cause, whining while accelerating can also be caused by low power steering fluid or more serious damage like faulty alternator bearings, a malfunctioning water pump, a broken piston or a bad AC compressor.
How Long Should My Power Steering Pump Last? A. There`s no set expiration date for your power steering pump. That said, you should count on having to replace the pump after 100,000 miles or so.
BlueDevil Power Steering Stop Leak permanently seals leaks in power steering, differentials, and worn rack and pinion systems. It`s safe and easy to use and guaranteed to work to stop leaks. BlueDevil Power Steering Stop Leak works on gasoline or diesel engines.
Red Fluid. There are two fluids used by your vehicle that are red. These are the automatic transmission fluid and the power steering. Both of these are hydraulic fluids.
