Kia Ceed 1.4 T-GDI G4LD (2018): Timing Chain Removal and Installation

The G4LD engine (Kappa series, 1.4 T-GDI) uses a timing chain drive with a hydraulic tensioner and variable valve timing phasers on the camshafts. This is an interference engine: if the timing marks are set incorrectly, the valves will hit the pistons. The general procedure is below. Check exact torque specs and mark positions against the manufacturer's service manual for this engine.

Difficulty: Hard Time: 6-10 hours (for an experienced mechanic) Steps: 14 Tools: Socket set and ratchet, torque wrench, crankshaft or flywheel holding tool, camshaft locking tools (special tools for this engine), crankshaft pulley puller, floor jack with a wood block or an oil pan support stand, sealant for mating surfaces, syringe or wire to lock the tensioner, containers for oil and coolant.

Part

  • 🔩 Timing chain kit for the G4LD: chain, chain tensioner, chain guide (slipper) and tensioner arm. Also needed: front crankshaft seal, gaskets and seals for the timing cover and valve cover, and the crankshaft pulley bolt (single-use). Sprockets are replaced based on condition.

Step by step

14 steps
  1. Disconnect the negative battery terminal. Raise the front of the car and remove the engine undercover. Drain the engine oil and coolant. Remove the air ducts and the intercooler if they block access.
  2. Remove the right front wheel and the fender liner. Remove the accessory drive belt together with its tensioner.
  3. Place a floor jack with a wood block under the oil pan. Remove the right engine mount with its bracket to get access to the timing cover. The engine must remain securely supported.
  4. Remove the ignition coils, spark plugs and valve cover. Watch the gasket and the spark plug well seals.
  5. Rotate the crankshaft in its normal direction of rotation using the pulley bolt until the cylinder 1 TDC marks align. The mark on the pulley or timing cover must line up with the mark on the camshaft sprockets. Check the marks on the sprockets themselves and on the chain to confirm you are at TDC on the compression stroke, not the exhaust stroke.
  6. Lock the crankshaft to prevent it from turning. Loosen the pulley bolt and remove the pulley. The removal and tightening torques for the pulley bolt on this engine are not clearly documented in open sources. Tighten it strictly to the manufacturer's specification, and replace the bolt with a new one.
  7. Remove the oil pan bolts in the timing cover area if they hold the cover. Remove the timing cover, carefully separating it from the old sealant. Do not pry with a screwdriver across the mating surface, to avoid damaging the sealing surfaces.
  8. Lock the chain tensioner (with the locking pin or a wire through the service hole), then remove the tensioner. Do not unbolt or remove the tensioner until the marks have been made.
  9. Mark the chain and sprockets with paint if the factory marks are missing or hard to see. Remove the chain guide and tensioner arm. Remove the chain, then the sprockets if necessary. Inspect the sprockets for tooth wear. Inspect the variable valve timing phasers and the oil pump drive (if it is chain-driven).
  10. Install the new chain, guides and tensioner. Align the marks on the camshaft and crankshaft sprockets with the marks on the chain, and keep the chain taut on the tensioner side. Install the tensioner and remove its locking pin.
  11. Double-check that the marks still line up. Install the timing cover with a new crankshaft seal and fresh sealant on the mating surfaces. Tighten the bolts in the proper sequence and to the torque specified by the manufacturer. Allow the sealant to cure according to the instructions on the tube.
  12. Install the pulley with a new bolt and tighten it to the manufacturer's specification. Turn the crankshaft by hand two full revolutions in its normal direction of rotation. The marks must return to the TDC position. If they do not match, disassemble and reposition the chain.
  13. Reassemble everything in reverse order: valve cover with a new gasket, spark plugs, ignition coils, engine mount, belt, wheel, undercover. Fill with fresh oil and coolant, and bleed the cooling system.
  14. Start the engine. Check for oil and coolant leaks and for smooth running without unusual noises. Check adaptations and fault codes with a scan tool. Warm up the engine and check the fluid levels.

Common mistakes and warnings

  • This is an interference engine. Being off by even one chain link will bend the valves. Do not turn the crankshaft with force if you feel resistance: stop and check the marks. If the chain is stretched, you get camshaft correlation fault codes, or you hear noise on a cold start, check the variable valve timing phasers and the oil pressure. If you do not have the special tools for locking the camshafts and experience with timing drive work, leave the job to a repair shop.
