Engine Belt 07K145933T: Precise Compatible Models & Core Function
Analysis
I. Precise Compatible Models (2017–2025)
This belt is exclusively designed for Volkswagen Group EA855 series
2.5T five-cylinder high-performance engines, covering the following models:
1. Audi TT RS (Chassis Code: 8S)
• Production Years: 2017–2023
• Engine Models: CAEB (400PS), CRCA (450PS)
• Versions: Coupe (2-door), Roadster (convertible), including models with RS
Performance package.
2. Audi RS3 (Chassis Code: 8V)
• Production Years: 2018–2023
• Engine Models: CAEB (400PS), CRCA (450PS)
• Versions: Sedan (4-door), Sportback (5-door), including limited-edition RS3
Performance models.
3. Audi RS Q3 (Chassis Code: F3)
• Production Years: 2019–2025
• Engine Model: CAEB (400PS)
• Versions: SUV, Sportback (coupe-SUV), excluding standard Q3 models (the
standard version uses the EA888 engine with a different belt
model).
II. Core Functions: The Power Hub of High-Performance Engines
Adopting a 10-ribbed poly-V belt structure, this belt is tailored
for the high-speed, high-torque operating conditions of the EA888
engine, fulfilling the following key roles:
1. Linked Drive for Multiple Components
• Alternator: Supplies power to the vehicle’s electrical systems (e.g.,
headlights, air conditioning, audio), ensuring stable power during
vehicle startup and driving.
• Air Conditioning Compressor: Activates the refrigeration cycle via belt drive to maintain a
comfortable in-cabin temperature.
• Water Pump: Drives the circulation of coolant to prevent the engine from
overheating under high-load operation (e.g., during track driving,
the oil temperature of the EA855 engine can reach 120°C, requiring
efficient heat dissipation).
2. High-Strength Power Transmission
• 10-Rib Design: Compared with standard 6-rib belts, the contact area is increased
by 40%, enabling it to transmit over 600N・m of torque—perfectly
matching the 480–500N・m peak torque of the EA855 engine.
• Aramid Fiber Reinforcement: The belt’s internal aramid cord core
(e.g., DuPont Kevlar) provides a tensile strength of 3000N (vs.
approximately 2000N for standard belts). It maintains stable
transmission even at the 6500rpm redline speed, avoiding power
loss.
3. High-Temperature Resistance & Anti-Aging
• EPDM Rubber Material: Withstands extreme temperatures ranging from -40°C to 150°C,
making it suitable for the high thermal loads of RS models during
track driving (temperatures near the turbocharger can reach 130°C).
• Oil-Resistant Surface Coating: Resists erosion from turbocharger
oil vapor. Tests show no hardening or cracking within 100,000
kilometers, extending its service life by 30% compared to standard
belts.
4. Adaptability to Compact Layouts
• Short-Path Design: With a total length of 1235mm (tolerance ±0.5mm), it routes around
the high-temperature area of the turbocharger, avoiding the slack
caused by thermal expansion in traditional belts.
• Optimized Tensioning System: When paired with the original
equipment (OE) tensioner (07K145933T-Tensioner), it automatically
compensates for belt elongation within 0.1 seconds, ensuring stable
transmission.
