Volkswagen Multivan 2.0 TDI CAAC 140 hp (2004): Timing Belt and Roller Replacement

The CAAC uses a timing belt drive, and if the belt breaks, the valves will hit the pistons, which means an expensive repair. The job requires precise alignment of the marks and lock tools, so it must be done carefully. Replacement interval: about 90,000-120,000 km or 5 years, whichever comes first. Replace it more often under severe operating conditions.

Difficulty: Hard Time: 4-7 hours Steps: 13 Tools: Socket and wrench set, torque wrench, factory timing lock tool kit for 2.0 TDI diesels (crankshaft lock, camshaft lock, high-pressure pump lock), jack or lift and safety stands, pulley holding tool, marker, coolant drain pan

Part

  • 🔩 Timing belt kit for 2.0 TDI T5 — toothed belt, tensioner roller, idler rollers. It is recommended to replace it at the same time as the water pump, and if needed the serpentine belt and its roller. Check the kit contents (number of rollers) against your engine. If the crankshaft pulley bolts and tensioner bolt need replacing, they are single-use and are a separate item

Step by step

13 steps
  1. Shut off the engine and let it cool down. Disconnect the negative battery terminal. Open the hood and remove the lower undertray. Drain some of the coolant if you are replacing the water pump.
  2. Remove everything that blocks access to the front of the engine: the air duct and intercooler pipes, the decorative cover, and the serpentine belt (note its direction if you will reinstall the belt). If needed, loosen or remove the right front wheel and the wheel arch liner.
  3. Support the engine from below, with a pad under the oil pan. Remove the right engine mount as far as needed to access the upper belt cover. Remove the upper, middle and lower timing belt covers.
  4. Remove the crankshaft pulley (the bolts that attach it to the damper) to get access to the lower cover and the crankshaft mark. Lock the crankshaft when loosening the bolt as specified in the service manual. Do not turn the engine with a wrench on the pulley bolt.
  5. Turn the crankshaft clockwise to TDC of cylinder 1. Align the marks: on the camshaft gear, and at TDC on the crankshaft. Lock the crankshaft, camshaft and high-pressure pump gear with the factory lock tools. If the marks do not align or a lock tool will not go in, do not continue. Recheck the engine position.
  6. Loosen the tensioner roller and remove the belt. Note the belt routing and the position of the rollers. Remove the tensioner and idler rollers. If you are replacing the water pump, remove it as well.
  7. Check the gears and mounting surfaces for wear and play. Wipe the toothed surfaces dry, and replace the seals if there is an oil leak.
  8. Install the new rollers and the water pump with a new seal. Tighten the fasteners to the torque specified by the manufacturer for your engine. Approximate values: rollers 20-45 N·m (15-33 lb-ft), water pump 15-20 N·m (11-15 lb-ft). Use new bolts for any bolts that use angle tightening.
  9. Install the new belt following the routing in the service manual: first onto the crankshaft, then in the direction of travel over the rollers, water pump and gears, and install the tensioner roller last. Do not bend the belt sharply, and do not let oil or coolant get on it.
  10. Adjust the tension using the tensioner mark as specified in the service manual (for automatic tensioners, use the indicator). Tighten the roller to the specified torque.
  11. Remove all lock tools. Turn the crankshaft by hand two full turns clockwise and make sure the marks line up and the lock tools go in freely. Check the belt tension again. If the marks do not line up, reinstall the belt.
  12. Install the protective covers, the engine mount, the crankshaft pulley (with a new bolt, tightened by angle as specified in the service manual) and the serpentine belt. Reassemble the air pipes and reconnect the battery.
  13. Refill the coolant and bleed the cooling system until the air is out. Start the engine, warm it up and check for leaks and unusual noises. If needed, clear fault codes with a diagnostic scanner. Write down the mileage at the time of replacement.

Common mistakes and warnings

  • Never turn the crankshaft with the belt removed until the lock tools are removed, or the valves may hit the pistons. Do not time the engine "by eye" using the marks alone without the factory lock tools: being off by even one tooth causes power loss, fault codes and engine damage. If you lack experience, it is better to leave the job to a repair shop, because incorrect installation will lead to a complete engine rebuild. Check the exact tightening torques and bolt tightening angles for your engine against the manufacturer's service manual.
