Skoda Octavia 2.0 TDI BKD (2008): Timing Belt and Water Pump Replacement

The timing belt on the BKD engine must be replaced every 120,000 km or 4-5 years, whichever comes first. The procedure is difficult. It requires special tools to lock the shafts and precise alignment of the timing marks. A mistake lets the valves hit the pistons and leads to an engine overhaul. Always replace the water pump together with the belt.

Difficulty: Hard Time: 4-6 hours Steps: 21 Tools: socket and wrench set, torque wrench with angle gauge, special tools: crankshaft locking pin T10050, camshaft locking tool T10051, jack, engine support

Part

  • 🔩 Timing belt kit 03L198119 (includes a 141-tooth × 30 mm belt, a tensioner roller and two idler rollers). Manufacturers: Gates, Contitech, INA. The water pump is replaced together with the belt. New crankshaft pulley bolts are required

Step by step

21 steps
  1. Work on a cold engine (do not run it for at least 4 hours).
  2. Remove the plastic engine cover and disconnect the negative battery terminal.
  3. Remove the front right wheel arch liner to access the drive belts and the lower crankshaft pulley.
  4. Raise the front of the engine with a jack, using a wooden block under the oil pan. Remove the right engine mount.
  5. Remove the accessory drive belt, then remove the drive belt tensioner.
  6. Turn the crankshaft clockwise (use a 19 mm socket on the pulley bolt) until the mark on the flywheel lines up with the slot in the clutch housing.
  7. Install the crankshaft locking pin T10050 in the slot in the clutch housing. The pin must enter the hole in the flywheel (access is through the starter location or from below).
  8. Install the camshaft locking tool T10051 on the rear side of the camshaft gear to keep the camshaft from turning.
  9. Remove the three crankshaft pulley bolts. Tightening torque on assembly: 10 N·m (7 lb-ft) + 90° additional turn. The bolts are single-use, so replace them with new ones.
  10. Remove the crankshaft pulley, and the lower and center timing belt covers.
  11. Loosen the tensioner roller nut, turn the roller counterclockwise to release the tension, and lock it in place.
  12. Remove the old timing belt. Inspect the tensioner and idler rollers for wear.
  13. Unbolt the water pump and remove it. Clean the mounting surface, then install the new pump with a new gasket.
  14. Replace the tensioner and idler rollers with the new ones from the kit.
  15. Install the new timing belt in a clockwise direction. Route it from the crankshaft pulley through the tensioner roller to the camshaft, then through the idler rollers and the water pump. Install the belt without tension.
  16. Tension the belt with the tensioner roller. Turn the tensioner clockwise with the special wrench or a hex key until the pointer on the housing lines up with the mark. Tighten the tensioner roller nut to 20 N·m (15 lb-ft) + 45° additional turn.
  17. Remove the crankshaft and camshaft locking tools, then turn the crankshaft by hand two full turns clockwise.
  18. Install the locking tools again. They must go in freely, which confirms the marks are aligned. If they do not go in, the marks are off. Repeat the belt installation.
  19. Check the belt tension visually. The tensioner pointer must be in the green zone.
  20. Reassemble in reverse order. Install the belt covers, the crankshaft pulley with new bolts (10 N·m (7 lb-ft) + 90°), the drive belt, the engine mount and the wheel arch liner.
  21. Connect the battery and start the engine. Listen for unusual noises from the timing drive. Shut the engine off and check the marks again.

Common mistakes and warnings

  • The BKD is an interference engine. If the belt breaks or the marks are off, the valves hit the pistons and the cylinder head needs an overhaul. Always use the special tools to lock the shafts. BKD engines are known for stripping the M8 tensioner roller bolt thread in the aluminum cylinder head. Be careful when tightening it and do not exceed the specified torque. Do not start the engine until you have rechecked the marks after turning the crankshaft two full turns.
