Timing chain replacement: Ford Mondeo01 2.5 Duratec-VE (LCBD)

🧭 Before you start

Disconnect the battery and remove the inlet manifold components, coils, wiring and cylinder head covers. Support the engine, remove the mounting bracket, alternator, power steering pump, crankshaft pulley, sump and front cover. Set the engine to TDC, mark the chains and remove tensioners, guides and chains from each bank. Fit the new chains to the marks, unlock the tensioners, check the timing marks, then refit covers with fresh sealant, renew seals and gaskets, refill the oil and reconnect the battery.

Fits: platform codes 2.5, DURATEC-VE, V6, 24V

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

Don't miss
