The serpentine belt is one long, snaking, winding belt that keeps your alternator, power steering pump, air conditioning and—in some cases—your water pump running smoothly and effectively.
In addition to making noise, the belt may be slipping. This may cause intermittent power steering especially under demand. This is seen when the belt has stretched and is almost to its failure point. Most commonly this occurs when turning tightly or placing high demands on the power steering system.
It is usually located on the front of the engine and is in charge of operating the entire power-steering hydraulic-fluid pump. What this means is that the belt is tasked with making sure that the power steering is actually accessible to the driver.
The timing belt is responsible for making sure the engine’s crankshaft, pistons, and valves operating insync or in time. … The drive belt is responsible for using the engine’s revolutions to drive the power steering pump, a/c compressor, alternator, water pump, and other belt driven accessories.
Is it safe to drive a vehicle without power steering fluid? – Quora. No it’s not. While you CAN drive without it, the potential failure could result in stranding you on the side of the road.
A typical serpentine belt start at around $25 and goes up to $75 at most. If you know some car repair basics, you could change the belt yourself, and it may save you paying labor charges somewhere between $75 and $120. All together, you’re looking at around $100 to $195 to replace your serpentine belt.
Most automakers recommend replacing the timing belt every 60,000 to 105,000 miles. Timing chains are heavier and more complex than timing belts, but they also last much longer. Really, unless there’s a problem, timing chains don’t have a replacement interval.
Driving with a bad belt tensioner is unsafe since the tensioner is meant to guarantee ample tension that powers accessories. Wear on the belt tensioner will eventually cause the belt to slip, generate loud noise, and also create an unsafe level of heat along the accessory pulleys.
There is no recommended timeframe in which to replace your tensioner, especially as the belt itself usually needs replacing before the tensioner does. However, you should inspect your tensioner each time you service your car to monitor its condition and replace it if necessary.
Symptom 1: Squealing, rattling, or chirping.
When the tensioner or tensioner pulley fails, the loss of tension can cause the belt and pulleys to make high-pitched rattling or chirping noises. If the pulley bearing completely fails, it can also cause a squealing or even a grinding noise.
The average cost to repair a power steering pump is somewhere between $200 and $350. To replace the power steering pump with a new part, it will cost between $400 and $800 (depending on car model and what shop you take it to).
I wouldn’t recommend driving while the power steering belt is broken; not only because it is a safety issue, but also because it can cause additional damage to power steering systems. I’d recommend having your power steering belt replaced as soon as possible; and before you drive the vehicle further.
How long does it take to replace a timing belt tensioner? Step 1: Preparation. First, prepare your car and work area. Changing a timing belt and water pump can take anywhere from 1-3 hours depending on your skill level, so make sure you have the time and space to complete the job.
Is a timing belt more like a belt and pulley system or a sprocket and chain system? … A timing belt is more like a sprocket and chain system because they have teeth that engage with notches in the pulleys on the crank and camshaft.
V belt is shaped like a V and drives things like power steering pump, alternator and air con compressor. Commonly cars have more than 1 V-belt btw. … Timing belt is inside a cover and it connects the crankshaft with your camshaft to keep your valves opening properly. A timing belt has cogs so it can't slip.
Auto manufacturers started using timing belts because they are much less expensive to manufacture and they run more quietly. … They’ll stay tight without damaging much (like timing chain teeth for a timing chain), but when they go, they’ll go. The good news is that belts are much easier to replace than a timing chain.
Timing Belts Are Quieter and Less Expensive to Manufacture
Quieter and less expensive than chains, with some able to last as many as 100,000 miles, timing belts eventually became the go-to choice for automakers right up through the 1990s.
You will pay somewhere between $125 and $380 to have your tensioner pulley replaced. The labor should run between $45 and $155, while parts can cost as little as $85 or as much as $225.
Causes of Belt Tensioner Wobbling
In general, belt tensioners tend to get noisy when they fail. If your belt tensioner is chirping or makes other noises, it is often an indication that the part is old and needs to be replaced. You can even remove the belt, spin each pulley, and listen for rumbling or other noises.
Noises that indicate your drive belt may be misaligned
A chirp is a repetitive, high-pitched noise that doesn’t last long, and is usually worse when the engine is idling. … A squeal, on the other hand, is a chirp that gets louder and increases in volume along with engine speed.
Angular misalignment refers to pulleys which are within the drive system plane, but are tilted because their shafts are not parallel. Both misalignment conditions can create belt tracking problems, excessive wear, a chirping noise, and belt stability problems.
While all of the pulleys may be running true, one or more of them could be sitting too far forward or back on its shaft. A common source of parallel misalignment is improper installation depth of press-fit pulleys, like those found on power steering pumps.
Any damage to the automatic tensioner pulley can cause damage to the belt tensioner due to the vibrations caused by the pulley. Physical damage to the pulley is an indication of extreme tension or physical interference.
When the tensioner fails, the serpentine belt will slip off and break. When this happens, the alternator, power steering pump, and AC compressor will stop working. Since there is no belt turning the pulley, the battery light will turn on, and steering will be difficult. The AC compressor will also stop working as well.
If the drive belt tensioner pulley has any sort of issue it can cause unusual and accelerated wear on the belt. A bad pulley can cause fraying on the edges of the belt, and in severe cases can even cause it to break. Other symptoms of a bad belt tensioner is failure of the belt driven accessories.
