SsangYong Actyon 2.0 G20D (2013): Timing Chain Replacement

The G20D (an engine family shared with the Kyron and Korando) has a chain-driven timing system. The chain lasts a long time, but with poor lubrication and low-quality oil it stretches and the tensioner starts to rattle. Exact torque values and timing marks for this engine are not described in detail in publicly available materials. Below is the general work sequence, and you should check the tightening values against the manufacturer's service manual.

Difficulty: Hard Time: 6-10 hours (including removal of the front accessories and checking the timing marks) Steps: 12 Tools: Socket and ratchet set, torque wrench, crankshaft pulley puller, pulley/flywheel holding tool, Torx and E-Torx set, jack and jack stands, containers for oil and coolant, sealant for the oil pan and front cover, flashlight, marker or paint for marks.

Part

  • 🔩 Timing drive kit for the G20D: timing chain, chain tensioner, chain guides (shoes), sprockets if worn, front cover gaskets and seals, engine oil and coolant. Choose exact part numbers by VIN, since tensioner versions differ among engines of this series

Step by step

12 steps
  1. Preparation. Disconnect the negative battery terminal. Put the car on a lift or over a pit, and remove the engine skid plate. Drain the engine oil and coolant.
  2. Removing the accessories. Remove the air duct and intake tract, the accessory drive belt, the pulleys and tensioner, and if necessary the alternator, the power steering pump and the cooling system hoses. With the front cover removed, support the engine with a jack stand under the oil pan if you remove the right engine mount.
  3. Remove the valve cover. First disconnect the ignition coils and sensors. Remember where the connectors go and take photos.
  4. Set the No. 1 cylinder piston to TDC on the compression stroke. Align the timing marks on the camshaft sprockets and the crankshaft sprocket with the factory marks. Mark the position with a marker if the chain links are not marked.
  5. Remove the crankshaft pulley. Use the holding tool and a puller, and do not hammer on the pulley. The pulley bolt is very tight, so use a long breaker bar or a brace.
  6. Remove the oil pan (if the front cover design requires it) and the engine front cover. Remove all of the old sealant and degrease the surfaces.
  7. Remove the chain tensioner (first release the pressure with the locking pin, if one is provided), the chain guides and the shoes. Remove the old chain.
  8. Inspect the sprockets, shoes and guides. If the teeth are hooked or there is scoring, replace the sprockets together with the chain. Do not install a new chain on worn sprockets.
  9. Install the new chain, aligning the marks exactly with the marks on the sprockets. Install new shoes and a new tensioner. Do not release the tensioner lock until everything is in place.
  10. Tighten the tensioner and shoe fasteners to the specified torque. Turn the crankshaft by hand through 2 revolutions and check that the marks line up again at TDC. If they do not, the chain was installed with an offset, so repeat the installation.
  11. Reassemble in reverse order: front cover with new sealant and gaskets, new crankshaft seal, pulley, oil pan, valve cover with a new gasket, then the accessories. Tighten the pulley bolt to the specified torque.
  12. Fill with new oil and a new filter, and add coolant, then bleed the air from the system. Start the engine and let it idle, then check for leaks and for any chain noise. Read the camshaft timing fault codes and clear them if necessary.

Common mistakes and warnings

  • If the marks do not line up or the chain has jumped even one tooth, the valves can hit the pistons. Turn the crankshaft by hand only. Do not start the engine until you have checked the marks after two revolutions. If you have no experience with timing chain drives, it is better to leave the job to a repair shop.
