Contitech CT1139 K2 Timing Belt Kit

Contitech CT1139 K2 Timing Belt Kit

The Contitech CT1139 K2 Timing Belt Kit is a high‑performance component designed for the timing system of Volkswagen, Audi, Skoda, and Seat engines. It replaces the original timing belt (Zahnriemen) with a durable, precision‑made alternative that ensures reliable engine operation under demanding conditions.

Key Features

• Exact Fitment: The kit is engineered to match the OEM specifications for engines such as the 1.6TDi and 2.0TDi, guaranteeing seamless integration without modification.
• Durable Construction: Made from high‑grade rubber reinforced with steel cords, the belt resists wear, heat, and oil exposure, extending service life compared to standard belts.
• Precision Teeth: With 160 precisely machined teeth, the belt maintains accurate timing alignment between camshaft and crankshaft, preventing misfires or engine damage.
• Comprehensive Kit: Includes all necessary components: the main timing belt, idler pulleys, tensioner, and mounting hardware. This eliminates the need for additional parts during installation.
• Compatibility: Suitable for a wide range of models—Volkswagen Golf VI (5K1), Audi A3 8P, Skoda Fabia II, Seat Leon, and many others that use the CT1139 K2 specification.

Installation Overview

The installation process follows standard timing belt replacement procedures but benefits from the kit’s pre‑assembled components. A typical sequence includes:

1. Remove Old Belt: Detach the existing timing belt and associated pulleys.
2. Install New Pulleys: Mount the supplied idler and tensioner pulleys onto their designated positions.
3. Fit the Timing Belt: Loop the new belt around the camshaft, crankshaft, and all pulleys, ensuring correct tooth alignment.
4. Tighten Tensioner: Adjust the tensioner to achieve optimal belt tension as specified by the manufacturer.
5. Verify Timing: Rotate the engine manually to confirm that cam and crank positions match the OEM timing marks.

Performance Benefits

• Enhanced Reliability: The reinforced construction reduces the risk of belt failure, a common source of costly engine damage.
• Improved Efficiency: A properly tensioned and aligned belt minimizes friction losses, contributing to better fuel economy.
• Longer Service Intervals: Users report extended intervals between replacements compared to standard belts, thanks to the durable materials.

Maintenance Tips

• Inspect the belt for cracks or fraying before each engine start, especially after a long drive or high‑temperature operation.
• Check tension regularly; a loose belt can slip and cause timing errors.
• Avoid over‑tightening the tensioner, which may lead to premature wear of the belt’s rubber core.

Compatibility Summary

The CT1139 K2 kit is tailored for engines that originally use the CTAM 160‑tooth timing belt. Common vehicle models include:

• Volkswagen Golf VI (5K1)
• Audi A3 8P, A4 B8, A5 Q3, Q5, and other 8P/8PA variants
• Skoda Fabia II, Octavia, Superb II
• Seat Leon, Ibiza, Alhambra, and other SEAT models
• Volkswagen Passat B7, T5 Transporter, Tiguan (5N), Touran (1T1/1T2)

Engine types covered include the 1.6TDi and 2.0TDi inline‑four configurations, as well as certain naturally aspirated engines that share the same timing architecture.
