Hyundai Genesis 2.0T Timing Chain Install EM-31: Valve Cover & Pulley Torques
Timing system procedure for installing the cylinder head cover and crankshaft pulley with torque sequence and specs.
This is page EM-31 from a Hyundai factory service manual's Timing System section, covering the final reassembly steps after timing chain installation. Step 10 details installing the cylinder head cover: removing hardened sealant between the timing chain cover and cylinder head, applying Loctite 5900H sealant with a 2.5 ± 0.5 mm (0.098 ± 0.019 in.) bead width, assembling within 5 minutes, and avoiding firing/blow-out tests for 30 minutes afterward. Cover bolts are torqued in two steps (3.9–5.9 N.m, then 7.8–9.8 N.m) following an 18-position numbered sequence shown in a diagram. Step 11 covers installing the crankshaft pulley (torque 166.7–176.5 N.m / 122.9–130.2 lb-ft) with a NOTICE to hold the crankshaft using SST 09231-2M000 and 09231-2J210. Step 12 gives torques for the water pump pulley (9.8–11.8 N.m) and idler (53.9–63.7 N.m), and Step 13 covers the tensioner bracket assembly (39.2–44.1 N.m). Diagrams (illustration codes SNFEM8045D, SBKEM9105D, SBKEM9102D) show the sealant path, bolt sequence, and front accessory pulley layout with callouts A–D. A reader learns all torque specs and sealant procedures for reinstalling the valve cover and front pulleys after a timing chain job.

Frequently asked questions
- What is the torque spec for the crankshaft pulley bolt?
- 166.7 ~ 176.5 N.m (17 ~ 18 kgf.m, 122.9 ~ 130.2 lb-ft). The crankshaft must be held with SST 09231-2M000 and 09231-2J210 when installing the bolt.
- What sealant is used on the cylinder head cover and how should it be applied?
- Loctite 5900H with a bead width of 2.5 ± 0.5 mm (0.098 ± 0.019 in.). The cover must be assembled within 5 minutes of applying sealant, and hardened old sealant between the timing chain cover and cylinder head must be removed first.
- What is the cylinder head cover bolt torque sequence?
- Bolts are tightened in two steps following the numbered 1–18 sequence shown in the diagram: Step 1 is 3.9 ~ 5.9 N.m (2.9 ~ 4.3 lb-ft) and Step 2 is 7.8 ~ 9.8 N.m (5.8 ~ 7.2 lb-ft).
- What are the water pump pulley and idler torque specs?
- Water pump pulley (B): 9.8 ~ 11.8 N.m (7.2 ~ 8.7 lb-ft). Idler (C): 53.9 ~ 63.7 N.m (39.8 ~ 47.0 lb-ft).
- How long after installing the cylinder head cover before running the engine?
- The firing and/or blow out test should not be performed within 30 minutes after the cylinder head cover is assembled.
