If you’ve noticed a power steering noise when cold, there are a few possible causes. A worn belt can cause this noise, which amplifys upon starting the vehicle and when the driver turns the steering wheel. When it’s cold, the rubber in a serpentine belt becomes stiff, making it difficult for it to maintain a tight grip on the pulleys. When this occurs, a squealing noise is generated.
Symptoms
If you hear a whining noise coming from your power steering, the problem is likely to be with your power steering pump. These problems are very common in cold weather, and the good news is that they are easy to fix. The problem can be as simple as a belt slipping on its pulley or a faulty power steering pump.
The reason why this problem happens is that the power steering pump is not getting warm enough. When the fluid is too cold, the pump will start to rattle and may not provide adequate lubrication. To fix the problem, you should check the fluid levels.
Causes
A whirring or whining sound coming from the power steering is common when the vehicle is cold. This noise is often caused by the serpentine belt slipping. The noise will increase in frequency and volume. The noise is especially noticeable when turning the steering wheel. If this noise is coming from the power steering system, you should replace the belt.
This noise is a result of the power steering fluid getting thicker in cold weather. This makes it harder for the pump to move the fluid. It is important to remember that older power steering fluid tends to be thicker than newer fluid.
Fixes
A common cause of power steering noise on cold engines is a defective O-ring in the inlet joint of the steering pump. This problem typically occurs when the steering fluid is cold and does not lubricate properly. Luckily, there are a few simple fixes to this problem.
First, it may be time to change your power steering fluid. This fluid can become dirty or gummed up in cold weather and can cause a whine and other unpleasant sounds. While some whining noise is normal during cold weather, a constant whine is a signal that your power steering system needs a service.
Another common cause of power steering noise when cold is an overly thickened power steering fluid. In extremely cold temperatures, power steering fluid can even freeze. When this happens, drivers may experience a loud, metal-on-metal noise when steering their vehicle. A solution to this problem is to change the power steering fluid with a full synthetic one.
BlueDevil Power Steering Stop Leak
If you have a leak in your power steering system, you can use BlueDevil power steering stop leak to permanently seal the leak. This product works on both gasoline and diesel engines and can be applied quickly and easily. It works by filling up the leak and sealing the rack and pinion system. It also reconditions worn rubber seals.
Power steering stop leak fluid is very similar to other fluids. However, it’s important to choose the right one for your vehicle based on the size of the engine. A small car will need a smaller fluid than an SUV, and vice versa. Large vehicles need a different fluid, specifically made for them.
Changing power steering fluid
If you’re having problems with power steering noise when cold, you may want to consider changing the fluid. This is a relatively simple process, and it works for vehicles of all types. Before attempting this repair, make sure you have the proper tools. You can use a turkey baster or fluid extractor to remove the old fluid. Then, place a new can of power steering fluid in the reservoir. Turn the steering wheel from lock to lock a couple of times, to ensure that the new fluid is in the correct level.
When the cold weather hits, power steering fluid can thicken and freeze. This can cause a loud metal-on-metal noise. Changing the fluid can help to prevent this problem. However, it’s important to remember to follow the manufacturer’s instructions for the correct level of fluid.
