Removing, installing and tensioning toothed belt, engine code AJH — VW

🧭 Before you start

Fits: VW Sharan I / SEAT Alhambra (7M)

• Timing position: the crankshaft or camshaft is set and locked during this job

Don't miss

• Mark direction of rotation of toothed belt.
• Set camshaft pulley to TDC No. 1 cylinder by turning crankshaft. Marking on camshaft toothed belt pulley must align with mark on cylinder head cover.
• If necessary, align ram before tensioning using long nose pliers or thin wire. (Hole in ram and hole in housing must align.)
• When camshaft is turned, crankshaft must not be at TDC. Danger of damage to valves and piston crowns.
• Align mark on camshaft toothed belt pulley with mark on cylinder head cover.

🔩 Torque settings

Values can differ between engine variants — check the code stamped on your block.

ℹ️ Always cross-check the exact figure against your vehicle's factory manual before final tightening — a wrong torque can damage the engine. These values are extracted from workshop data and may not cover every variant or revision.
