Range Rover Sport 3.0 TDV6 306DT (2012): Oil Pump Replacement

The oil pump on the 306DT sits deep inside the engine, and replacing it requires disassembling the front of the engine. The job involves removing the timing drive and locking the shafts with special tools. The exact step-by-step procedure and torque values for this engine are not confirmed in open sources, so the general principle is given below. Check all torque values against the manufacturer's service manual.

Difficulty: Hard Time: 8-14 hours (work is done from the front of the engine) Steps: 16 Tools: Socket and wrench set with a torque wrench, crankshaft pulley puller, camshaft and crankshaft timing locking tool set (special tool), jack or lift, jack stands, drain pans for oil and coolant, seal installation drift for the crankshaft seal, new gasket set and sealant.

Part

  • 🔩 Complete 3.0 TDV6 engine oil pump (genuine Land Rover). Related items: new crankshaft pulley bolt (single-use), front crankshaft seal, cover gaskets or sealant, engine oil meeting Land Rover specification (5W-30, WSS-M2C913-C type), oil filter, coolant

Step by step

16 steps
  1. Make sure the pump is actually the cause. Symptoms: low oil pressure on a warm engine and the pressure warning light coming on while the oil level is normal. First check the oil level and condition, the oil pickup screen, the pressure sensor and the pressure relief valve. The sensor or a clogged screen is often to blame, not the pump.
  2. Disconnect the negative battery terminal. Park the vehicle on level ground and let the engine cool down. Raise the vehicle and secure it firmly on jack stands.
  3. Remove the engine undertray. Drain the oil and coolant into clean containers.
  4. Remove everything that blocks access to the front of the engine: the grille, radiators and fan, drive belts, and the timing covers if necessary. Before disassembly, take photos of how the hoses and connectors are routed.
  5. Set the engine to TDC (top dead center) and lock the crankshaft and camshafts with the special tools. Do not disassemble the timing drive without the locking tools: the timing will be lost, and the pistons may hit the valves.
  6. Remove the crankshaft pulley. Its bolt is tightened to a high torque plus an additional angle, so it must not be reused.
  7. Remove the timing drive and tensioners as the service manual requires. Note the position of the chains and belt, and mark them if permitted.
  8. Remove the oil pan if access to the pump or pickup is not possible without it. On these engines the pan is usually sealed with sealant, so clean the mating surfaces without scratching them.
  9. Remove the oil pump by undoing its fasteners in sequence. Inspect the gears and housing: scoring, scratches and wear indicate a worn pump. Check the pump drive gear or shaft.
  10. Clean the mating surfaces of old sealant and gaskets, then degrease them. Flush the oil passages and the pickup screen.
  11. Before installation, fill the new pump with clean oil and turn it by hand so it does not run dry on the first start.
  12. Install the pump and tighten the fasteners in the sequence and to the torque specified by the manufacturer. Do not tighten by feel: the housing is aluminum and the threads strip easily.
  13. Install a new front crankshaft seal with a drift, square and without oil on the outer edge. Lubricate only the sealing lip.
  14. Reassemble the timing drive strictly by the marks and with the locking tools in place. Tighten the new pulley bolt to the torque and angle specified in the service manual. After assembly, turn the crankshaft by hand through two revolutions and make sure the marks line up and the engine turns without binding.
  15. Reassemble everything else in reverse order. Fill with fresh oil and coolant, and install a new oil filter.
  16. Before the first start, crank the engine with the starter with fuel delivery disabled (or the fuel pump fuse removed) until the pressure light goes out. Then start the engine and check the oil pressure, look for oil and coolant leaks, and check for fault codes in the engine control module.

Common mistakes and warnings

  • A mistake in setting the timing or using the old pulley bolt can cause serious engine damage. If you have no experience disassembling the timing drive on a V6 and do not have the required special tools, leave the job to a specialist shop. Do not drive the vehicle with the oil pressure light on: the engine will fail quickly. If the light is on, do not drive. Have the vehicle towed.
