1018002703 Multi wedge belt for Geely MK

Product Introduction

1018002703 Multi wedge belt for Geely MK

Our Multi Wedge Belt is a high-performance drive component for vehicle engine systems, featuring a multi-groove design that maximizes contact with pulleys. Made of heat-resistant EPDM rubber and reinforced with high-tensile polyester cords, it delivers strong power transmission while resisting aging, oil, and high temperatures (-40°C to 120°C).

Ideal for synchronizing multiple engine accessories (water pump, alternator, AC compressor), it prevents slippage, reduces noise, and ensures stable power output. Compatible with most passenger cars, SUVs, and light commercial vehicles, it meets OEM standards for fit and durability, offering a reliable replacement for worn or damaged belts.

Product Advantage

1.EPDM High-Temperature Resistant Material

Crafted from premium EPDM rubber, our multi wedge belt withstands -40°C to 120°C temperatures, 30% wider than standard neoprene belts. Lab tests confirm it resists hardening for 80,000+ km, maintaining flexibility even in extreme engine heat—ideal for high-performance multi wedge belt systems.

2.Reinforced Polyester Cord Structure

Embedded with high-tensile polyester cords (tensile strength 2,800 N/mm²), the belt reduces elongation by 50% under heavy loads. This minimizes slippage, ensuring stable power transmission to alternators, water pumps, and AC compressors—key for reliable multi wedge belt operation.

3.Precision Groove Design

Each wedge (3-6mm width) is engineered with 0.05mm tolerance, increasing pulley contact by 40% vs. single V-belts. The design distributes tension evenly, cutting noise by 25dB and boosting efficiency—perfect for multi accessory drive systems in SUVs and light trucks.

4.Oil & Chemical Resistance

Tested to ISO 1817 standards, the belt resists engine oil, coolant, and road debris. Our 5,000-hour immersion test shows <5% volume change, outperforming industry averages—extending multi wedge belt lifespan to 120,000 km in harsh conditions.

5.OEM-Grade Compatibility

Manufactured to match 98% of OE specs, it fits 1.5L-3.0L engines seamlessly. With a 0.03% defect rate and 2-year warranty, it’s a trusted multi wedge belt replacement for both DIY and professional mechanics.

Technical Parameters

1. Core material: The wheel body is made of SAE 1045 forged steel (tensile strength 600MPa), the bearings are made of high carbon chromium bearing steel (GCr15, hardness HRC 60-65), and the shell is made of 6061-T6 aluminum alloy, which is corrosion-resistant and lightweight, suitable for long-term engine compartment environments.

2. Size specifications: Wheel diameter 65-120mm (depending on the vehicle model, such as Ford commonly used 75mm, Toyota 85mm), thickness 12-25mm, installation hole spacing 30-80mm, standard M8-M12 (8.8 grade) high-strength installation bolts.

3. Bearing performance: Double sealed deep groove ball bearing, tolerance grade P5 (accuracy 0.001mm), radial clearance 0.005-0.012mm, filled with high-temperature lubricating grease (temperature resistance of 180 ℃), stable operation under -40 ℃ to 120 ℃ working conditions.

4. Tension parameters: Spring type automatic adjustment, tension range 15-50N (20-35N for household vehicles, 30-50N for commercial vehicles), adjustment accuracy ± 5N, effectively preventing the belt from slipping or breaking due to excessive looseness.

5. Extreme performance: Maximum sustained speed of 15000 RPM, instantaneous peak speed of 18000 RPM, designed service life of 150000 km (or 5 years), far exceeding the industry average standard of 100000 km.

6. Certification standards: Complies with ISO/TS 16949, SGS material certification, and ROHS environmental standards, undergoes triple quality inspection (size, tension, and speed testing), and has a factory defect rate of ≤ 0.02%.

Product Uses

Here are specific application scenarios of Multi wedge belt:

1. Daily commuting scenarios of family cars: Suitable for mainstream family cars, in response to the problem of belt aging caused by frequent engine start stop and short distance driving during daily commuting, its EPDM material can be used stably for more than 80000 kilometers, ensuring the normal operation of accessories such as water pumps and generators, and avoiding the impact of belt failures on daily travel.

2. SUV off-road and long-distance scenarios: Suitable for Jeep Compass, Volkswagen Tiguan and other SUVs, the belt needs to withstand higher tension and temperature during off-road bumps or long-distance high-speed driving. The precise groove design of the belt improves the pulley contact by 40%, reduces slippage, and can stably transmit even in low temperature environments of -40 ℃ or high temperature environments of 120 ℃, supporting complex road conditions.

3. Light commercial truck freight scenario: For light trucks such as Ford Transit and Iveco, the engine runs under high load for a long time during freight transportation, and the belt is susceptible to oil pollution and debris erosion. The product has passed the ISO 1817 oil resistance test, with a performance change of less than 5% after 5000 hours of immersion. Its service life of 120000 kilometers can reduce the number of repairs and minimize the loss of freight downtime.

4. Multiple vehicle repair scenarios in auto repair shops: When the auto repair shop receives multiple brand vehicle models, the belt is compatible with 98% OE specifications and compatible with mainstream engines ranging from 1.5L to 3.0L, eliminating the need for frequent stocking of different models. A low defect rate of 0.03% also reduces rework, improving repair efficiency and customer trust.

5. Renovation and maintenance scenarios for old vehicles: For old car models over 5 years old, the original belt is prone to hardening and cracking. Replacing the Multi wedge belt can restore the transmission efficiency of the engine, its anti-aging characteristics can extend the service life of the vehicle, and the installation does not require special tools, reducing the maintenance cost of old vehicles.

Product Operate Guide

1. Preparation before installation: Confirm that the belt model matches the vehicle, prepare a wrench and tension gauge, disconnect the power after the engine cools down, clean the surface oil and debris of the pulley, check for deformation, and avoid belt wear after installation.

2. Disassemble the old belt: Loosen the tensioner according to the vehicle maintenance manual, remove the old belt, record the belt winding direction (to avoid reverse installation), and if there are scratches on the pulley, it is recommended to polish or replace it simultaneously.

3. Install a new belt: Insert the new belt into each pulley in the original winding direction, adjust the tension wheel to the appropriate tension (refer to the manual standard, usually press the belt with your fingers to sink 10-15mm), and tighten the tension wheel fixing bolt.

4. Inspection and testing: manually rotate the belt to confirm there is no jamming, start the engine and idle for 5 minutes, listen for any abnormal noise, observe whether the belt runs off during operation, and complete the installation if there is no abnormality.
