Timing belt replacement: Jaguar S-Type X200 2.7 D (7B, 7G)

Step-by-step timing belt replacement for the Jaguar S-Type X200 2.7 D (7B/7G): 49 steps. What to remove, in what order, and what to check after.

On the S-Type (X200) with the 2.7 V6 diesel, engine codes 7B and 7G, the injection pump drive belt sits at the back of the engine against the bulkhead, and on left-hand-drive cars the brake servo is in the way. Access is the real job: scuttle panel grille, retaining strip, panel, wiper motors and mechanism, drain tube, then the master cylinder and brake servo come out before the pump belt cover can be removed. The belt itself is simple by comparison because it is not timed to the engine, but the tensioner is discarded and replaced. The engine must be cold, it must never be turned backwards, and on reassembly the servo-to-bulkhead gasket is renewed and the brake system has to be treated with the same care as the belt.

49 steps 2 engine codes

🧭 Before you start

Disconnect the battery and remove the engine cover, then work through the scuttle area: grille, retaining strip, panel, wipers and drain tube. Remove the master cylinder and brake servo to reach the injection pump belt cover. Remove the tensioner and belt, fit the new belt with a new tensioner and confirm it is seated correctly. Rebuild the bulkhead area with a new servo gasket and reconnect the battery.

Fits: platform codes V6, 2.7D

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

Don't miss

  • On LHD cars the brake servo and master cylinder must come out to reach the pump belt cover.
  • The pump drive belt is not timed to the engine, so no camshaft-to-crankshaft alignment is required.
  • Discard the old tensioner and check the new one is fitted correctly before closing up.
  • Work on a cold engine and never turn it against its normal direction of rotation.
  • Renew the brake servo to bulkhead gasket on reassembly.
  • After disturbing the master cylinder, confirm a firm brake pedal before the car moves; that is general workshop practice.

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.
