Timing belt replacement: Peugeot 406 Second assembly (EW10D)

Step-by-step timing belt replacement for the Peugeot 406 Second assembly (EW10D): 80 steps. What to remove, in what order, and what to check after.

This is the refit half of a timing belt job on the Peugeot 406 with the 2.0 16V HPi direct-injection petrol engine, code EW10D (RLZ). By this stage the old belt is off, the crankshaft and camshaft are pinned and the tensioner is held with its locking tool. Before the new belt goes on, check the tensioner and idler pulleys and renew them if they are rough. The belt is fitted in the set sequence, the tensioner is turned anti-clockwise with an Allen key until the pointer sits where it should, and the bolt is tightened. What decides the job: the engine must be cold when the tension is set, and the coolant pump bolts stay untouched. After ten crankshaft turns the pins have to drop back in.

80 steps 1 engine code

🧭 Before you start

With the crankshaft and camshaft locked, fit the new belt in the set sequence and tension it with an Allen key until the pointer is in position, then tighten the tensioner bolt. Remove the locking tools, turn the crankshaft clockwise 10 turns and check that the tensioner and the pins still line up; repeat if not. Refit the covers, crankshaft pulley bolt, engine mount, ECU, ancillary belt, splash guards and wheel, and reconnect the battery.

Fits: platform codes 2.0, 16V, HPI

  • Timing position: the crankshaft or camshaft is set and locked during this job
  • Special tools named: locking tool, locking pin

Don't miss

  • Set belt tension only with the engine cold.
  • Do not loosen the coolant pump bolts during the job.
  • If the tensioner marker cannot reach its mark, renew the tensioner pulley.
  • Turn the crankshaft clockwise 10 turns, then re-check tension and refit all locking tools.
  • Inspect the old belt for cracks, fraying or oil; oil contamination means a leak to fix first.

Who makes these pages, and how

TorqFix was built by a mechanic — after a 2,700 km drive with five roadside repairs that no diagnostic tool could explain.

The figures on this page come from manufacturer workshop documentation and are shown as they are. The page is assembled automatically from that data — it is not written by an AI. The AI works in the chat, where it answers for your specific car. It writes nothing here.

Variants of the same model differ. Cross-check torque against the factory manual for your engine before final tightening.
