Does a EPDM belt crack? EPDM belts inherently resist cracking because of the increased elasticity, so a visual check for cracks is not a true indicator of belt wear, especially since they can run 100,000 miles or beyond with no visual cracks. A far better indicator of wear on EPDM belts is material loss. This can result in belt hydroplaning.
How long do EPDM belts last? Most modern vehicles use belts made from ethylene propylene diene monomer, a synthetic rubber that lasts longer than older types of engine belts. Most belt manufacturers estimate the typical lifespan of an EPDM belt to be 50,000 to 60,000 miles, and some say it’s more than 100,000 miles.
What causes a belt to crack? Excessive cracking is usually caused by old age. Serpentine belts stretch with age and use; as time goes on, the rubber becomes dryer and less pliable making cracking more prevalent. However, cracking can also be caused by a defective tensioner. The tensioner is spring-loaded to keep the belt tight on the pulleys.
What causes AC belt to break? Serpentine belts can fail in a few different ways. This is usually the result of a belt in poor condition, or a problem with one of the accessory components being driven by the belt. A failed bearing in a pulley being driven by the serpentine belt will also cause the belt to break.
Does a EPDM belt crack? – Related Questions
What is EPDM belt?
Serpentine belts made of EPDM may last up to 100,000 miles or more before they have to be replaced. The original equipment belts on today’s late-model vehicles are mostly made of EPDM (ethylene propylene diene monomer), a synthetic rubber that is far more durable, heat-resistant and wear-resistant than Neoprene.
How do I know if my belt is EPDM?
Instead, EPDM belts wear out similarly to how a tire loses its tread over time. And just as one would check the tread depth on a tire, the best way to check for wear on an EPDM serpentine belt involves checking the rib valleys with a belt wear gauge.
What is the best indicator for wear on an EPDM belt?
EPDM belts can run 100,000 miles or beyond with no visual cracks. A far better indicator of wear on EPDM belts is material loss. Serpentine belt drives are exposed to grit, rocks, salt and water, and, over time, these contaminants along with slight misalignments result in wear of the rubber rib surface.
What happens if a belt breaks while driving?
What happens if the timing belt breaks? If a timing belt breaks, the engine will no longer work. If a timing belt breaks while driving in an interference engine, the camshaft stops turning leaving some of the engine valves in the open position. This will cause the pistons to strike the valves that left open.
What happens if your car belt breaks?
A broken serpentine belt can lead to a sudden loss of power steering in your car, making your steering very difficult to turn. A broken serpentine belt causes the water pump to stop circulating coolant through the engine’s cooling system, causing it to overheat.
Can you drive without a serpentine belt?
Under no circumstances can you drive a vehicle without a serpentine belt because the serpentine belt serves the important function of delivering antifreeze to important parts of the engine. The serpentine belt drives the water pump, and without it, there is insufficient coolant flow to maintain the engine temperature.
How expensive is it to replace a serpentine belt?
But what does a serpentine belt replacement cost? Of course, it depends on your make and model as well as labor costs, but in general a replacement serpentine belt costs around $70-$200 (plus taxes and fees), including around $50 for the belt and around $150 for the labor.
How long can a car run without serpentine belt?
How long will my car run with a broken serpentine belt? There are a few variables involved in the answer, but it should be able to run between 20 to 90 minutes. If it is a hot summer day, your engine can overheat very quickly without the coolant being pumped through the radiator.
What is the difference between neoprene and EPDM belts?
While EPDM is cheaper, noise resistant, and a good electrical insulator, neoprene is a thermal insulator resistant to chemicals, oil, and fire. Both rubbers are commonly used in gaskets, conveyor belts, and outdoor applications.
Is EPDM vulcanized rubber?
EPDM stands for Ethylene-Propylene-Diene-Monomer and is a type of synthetic rubber characterized by a wide range of applications. EPDM is typically vulcanized with sulfur; however, vulcanization can also occur using peroxides when sulfur-free rubber is required.
Does belt dressing work on serpentine belts?
Today, you should never put belt dressing on an EPDM-made serpentine belt. Belt dressing, and other oils and solvents, may quieten the belt noise when first applied, but these oils will actually cause the belt’s rib surface to become more aggressive once they dry out, leading to even more belt noise issues.
How do I know if my serpentine belt is healthy?
Check serpentine belts for wear
Lay the wear gauge in the ribs on the belt and run your finger across them. If the gauge sits flush with the top of the ribs, the belt is worn out.
Do drive belts crack?
Cracks and rot are, of course, indications that you should replace the drive belt. Any crack that’s more than halfway through the belt has to be replaced immediately. If your drive belt is damaged, don’t take chances. You could drive for miles without a problem, or you could end up stranded by the side of the road.
How long does a Gates serpentine belt last?
Q: How long do serpentine belts last? A: Most serpentine belts last between 50,000 and 100,000 miles, depending on the quality of the brand and your driving habits.
Can you drive on a tire with a broken belt?
You should NOT drive with a broken belt in your tire. Your tire(s) could potentially have a catastrophic failure such as a tire blowout, flat tire, or tire explosion.
How likely is a timing belt to break?
On average you can expect a timing belt to last 60,000 miles to 100,000 miles. This will change based on the make, model, and year of your vehicle.
What does a broken timing belt sound like?
A failing timing belt can produce a well-known “ticking” noise that will emanate from your engine. This ticking noise can also be a sign of low oil pressure within your engine, if you check your oil and your level is within a normal range, consult your mechanic to inspect your timing belt.
Is a serpentine belt the same as a timing belt?
Timing Belt. Don’t get confused—a serpentine belt is not the same thing as a timing belt. The timing belt is located inside the engine and keeps the crankshaft and camshaft in sync. This ensures that the engine intake and exhaust valves open and close in time with the pistons so the engine runs smoothly.
Can you replace a serpentine belt yourself?
You can replace a serpentine belt with ordinary hand tools. But we don’t recommend it. The spaces are often tight and the belt-driven devices difficult to reach. The belt placement tool allowed us to remove and properly place the new belt without reaching down into the pulley area.
Can low oil cause timing belt to break?
If there is no oil pressure on the tensioner, the belt will become loose and disengage from the pulleys. The timing belt can break if the camshafts don’t have enough to operate properly.
How often do serpentine belts break?
How often does a serpentine belt need to be replaced? Serpentine belts are built to last—much longer than before because of advancements in rubber technology. Under ideal conditions, a belt should stick with you for an average of 60,000 to 100,000 miles.
