- Camshaft locking tool – No.3268 or T10068.
- Crankshaft pulley holding tool – No.3273/3406 or T10069.
- Disconnect battery earth lead.
- Remove spark plugs to ease turning engine.
- Turn engine in normal direction of rotation (unless otherwise stated).
- Observe tightening torques.
- If fitted: Mark position of crankshaft position (CKP) sensor before removal.
- Do NOT turn crankshaft via camshaft or other sprockets.
- Do NOT turn crankshaft or camshaft with timing chain removed.
Valve timing procedures
- Timing chains located at rear of engine. Transmission removal required for repairs.
- Engine at TDC on No.1 cylinder  ,  or  .
NOTE: Ground tooth on crankshaft sprocket aligned with rear main bearing joint  .
- Ensure intermediate shaft sprocket timing marks aligned  .
- Fit locking tool to camshafts  . Tool No.3268.
- Remove tensioner(s) to ease timing chain removal/installation.
- During cylinder head repairs, with engine installed:
- Engine positioned correctly at TDC on No.1 cylinder  or  when slot on intermediate shaft sprocket visible  .
- If slot not visible, turn crankshaft one turn.
- Camshaft on early engines driven by duplex timing chain, tensioner MUST be bled before installation  :
- Push 0,8 mm wire through oil drilling up to ball valve  .
- Compress plunger into housing onto stop  .
- If plunger moves out again, repeat bleeding procedure.
- Camshaft on later engines driven by simplex timing chain:NOTE: All V5 engines have simplex timing chain.
- Tensioner has no oil drilling  .
NOTE: If replaced, ensure correct tensioner fitted.
- Tensioner MUST NOT be bled.
- Lubricate camshaft sprocket bolt mating face during assembly.
- Camshaft rotation can be prevented using 24 mm spanner at positions shown  .NOTE: DO NOT use camshaft locking tool  to prevent camshaft rotation.
- Install tensioner(s) after timing chain installation.
- After installation, reset lower timing chain tensioner:
- Release locking mechanism  . Use screwdriver.
- Push chain tensioner  against tensioner guide  .
- Tighten tensioner bolts  . Tightening torque: 10 Nm.
NOTE: Crankshaft pulley bolt MUST only be used once.
