Most car owners ask, “Can you lubricate belt pulley?” In this article, we will discuss extensively on this topic but before we dive in, let us discuss on what is a belt pulley.
A pulley is a device used to transfer torque from a motor’s belt to an object being lifted or moved. For example, a pulley helps transfer power from a belt to a fan or other machinery that needs extra traction. Belts are essential for transferring the power from the drive system to the machinery. The power is transferred via the belt to the wheel’s circumference and then into the object being moved or lifted. The power is then transferred back to the belt via the pulley and drive system.
Now you know the use of a belt pulley, let us dive into the topic.
Can you lubricate belt pulley?
Yes! You can lubricate your belt pulleys. The belt pulley lubrication consists of a grease pump that dispenses the grease onto the pulley and then a brush that spreads the grease evenly on both sides of the belt pulley. Melted oil can also be used in place of a grease pump and brush, but this method is not recommended unless the mechanics have previous experience with lubricating belt pulleys. For emergency lubrication, you can clean it with kerosene to remove any excess dirt and grime. Then spread a thin layer of oil over each side of the pulley with a cotton rag before replacing the belt.
Can you put WD-40 on idler pulley?
It is recommended that you DO NOT put WD-40 on the idler pulley. Heavier oils are not good for the belt, and lighter oils will make the belt slip after so long.
The straightforward answer is, yes! It does help some if you spray a little WD-40 on your idler pulley. We have heard this from many customers. If your idler pulley is squeaking, then apply some WD-40 and the squeaking will go away. But if there is any play in your belt and it slips off, then don’t use it or it could loosen things up even more so then that they cause you to replace other parts as well like pulleys and motors.
WD-40 was made for lubricating moving parts and machine parts, where you need to have fast-acting lubrication. As it is a water-based product and not an oil-based product it will not attract dirt to your pulley as a heavier oil would. So yes you can apply WD-40 to your idler pulley.

Can I grease a pulley?
You can grease a pulley wheel if it won’t turn smoothly, but be sure to remove the wheel from the machine before doing so. First, grease up your hands and the wheel with a suitable lubricant (spray oil works well). Then apply additional lubricant to the wheel with a cloth or paper towel. Now work the wheel back and forth slowly until it spins freely.
Can you lubricate belt tensioner?
Yes, you can lubricate belt tensioner. The belt tensioner is the device that keeps the timing belt tight, so it won’t slip or break. If there is too much slack in your timing belt, it can come off of its pulleys (the gear-shaped parts on which it runs). As a result, your engine could stop running; this means you can’t drive your car anymore until you fix the problem. So make sure that your belt tensioner is working properly at all times and then check once a year to make sure that your timing belt is still in place.
Can I spray wd40 on my alternator belt?
While it may be tempting to use WD40 as a quick fix for your squeaky/flexible alternator belt, WD-40 recommends against using its product for anything that is not intended by the manufacturer. While WD-40 does have limited uses in the automotive industry, I personally would not use it to lube or protect my alternator belt from heat or friction… As with most lubricants, WD-40 will wear off over time. Using a quality belt dressing like this one from 3M will protect against heat and friction caused by your drive belts.

How do I quiet a noisy belt tensioner?
A belt tensioner is a mechanical device used to hold the drive belt onto the pulley. A belt tensioner is vital because it provides consistent tension to the pulley and drive belt system, reducing stress on the bearings. However, the constant use of a belt tensioner can cause it to become noisy. To quiet your noise you can simply spray a lubricating oil on it such as WD-40 (use in well-ventilated areas), let it sit for 15 minutes, and wipe off any excess with a damp cloth.
Can you lubricate an alternator?
Yes, there are many reasons and instances when you may want to lubricate your alternator. You can do this by first loosening the belt and removing the serpentine belt. Secondly, you should remove the alternator belt shield and check for indications of oil or grease on the pulley wheel. Lastly, you can put a few drops of Mobil 1 Multi-Vehicle Fully Synthetic Oil on each of the three armature bearing caps before replacing them in order to protect against premature wear and tear.

Is White Lithium grease good for pulleys?
White lithium grease is a lubricant that is usually applied in the form of an aerosol. It’s a heavy-duty lubricant designed for metal-to-metal contact. Because lithium is a thickener, it not only offers structure to keep the oil in place, but it also serves as a sponge, releasing little amounts of oil as needed.
What are the advantages of spraying with WD-40 Specialist High-Performance White Lithium Grease?
There are various advantages, these includes:
- It lubricates for a long time.
- It won’t drip or run because of the high-viscosity recipe.
- It is good for load-bearing connections since it functions well under pressure.
- It has the ability to minimize friction and wear.
- Water and heat resistance make it ideal for outdoor use.
- Furthermore, the Smart Straw applicator allows you to spray in two different ways!
- For difficult-to-reach spots, such as inside chains, locks, or rollers, use the flip-up straw.
- To use the wide-angle spray eye for surface coverage, turn it down.
- You may utilize the 360° valve to effortlessly and efficiently work at any angle.
How can you silence a rattling drive belt?
The belt dressing should be sprayed directly onto the belt.
Because the fan belt will be moving swiftly as the engine runs, you can leave the can in one spot and spray the belt as it spins. Spray the belt dressing all over it until it is completely wet. The fan belt should almost instantly cease squeaking.
How do you lubricate a pulley on a belt?
It is very easy to lubricate a pulley on a belt, all you have to do is to simply take off the dust covers and add grease.
How do you stop a pulley from squeaking?
A squeal may be produced by a slipping drive belt at the alternator pulley. Most modern automobiles employ a serpentine belt system with an automated belt tensioner that cannot be manually adjusted. Problems with belt tension in these vehicles are frequently caused by a stretched, worn belt.
Will a squeaky belt be stopped by soap? When starting a car, a belt may screech for a few seconds before disappearing. When rubbed on a fan belt, regular bar soap will typically stop it from screeching. A few rubbings of bar soap on the belt can eliminate the screeching problem for a long time while also saving money.
What does a bad pulley sound like?
A screeching sound can be heard when the engine is running. This is due to the pulley’s bearings failing. The bearings may also make other sounds like clattering or even rumbling, giving the impression that there is something more wrong with the car than just a broken pulley.
