Product Description
This best-selling hydraulic timing chain tensioner with OE number 03F109507B is specially upgraded for VAG EA111 1.2 TSI petrol engines (CBZA 63kW/86HP, CBZB 77kW/105HP). All thread size, outer hexagonal dimension, internal spring elastic coefficient and hydraulic valve structure fully match OEM original specifications, supporting direct plug-and-play installation without adjustment during timing system maintenance.
- Reinforced high-strength alloy steel main body
The tensioner housing adopts high-precision forged alloy steel, surface anti-rust passivation treatment, resisting long-term high-temperature engine oil erosion. The thickened threaded wall improves tensile strength to avoid thread slipping during installation. The built-in high-fatigue resistant spiral spring maintains constant pre-tightening force after thousands of cold-start cycles, effectively solving timing chain slack problems of aging original tensioners.
- Optimized hydraulic damping internal structure
Adopts upgraded one-way hydraulic check valve design. It quickly builds stable oil pressure within 1–3 seconds after cold startup to eliminate obvious rattling noise from the engine compartment, a common fault of old CBZA engines. The internal hydraulic buffer absorbs chain vibration during acceleration and deceleration, restricts chain jumping teeth risk, and prevents valve-piston collision and severe engine damage caused by timing disorder.
- Perfect fit for full VAG 1.2 TSI vehicle range
Compatible models:
- Volkswagen: Golf Mk6, Polo, Caddy, Golf Plus, Touran, Jetta, Beetle
- Audi: A1, A3 8P
- Skoda: Fabia Mk2, Roomster, Yeti, Octavia, Rapid
- Seat: Ibiza, Leon, Altea, Toledo
- 1:1 OEM outline ensures seamless matching with timing chain guides and cylinder head mounting positions, no modification required for assembly.
- Strict multi-round factory quality inspection
Each tensioner undergoes hydraulic pressure retention test, spring fatigue cycle test, high-low temperature oil immersion aging test before delivery. It completely fixes typical timing system faults of CBZA engines: cold start chain rattle, timing chain elongation, chain jumping teeth, unstable engine idle, power drop and engine fault light alert.Flexible MOQ, customizable neutral export packaging, sufficient spot stock and 12-month warranty support one-stop bulk procurement for global VAG professional repair shops and auto parts distributors.
