Hyundai Genesis Coupe Valve Cover & Crank Pulley Install - Torque Specs EM-31
Service procedure for the timing system with cylinder head cover bolt torque sequence and tightening torque specifications.
This is page EM-31 of a Hyundai service manual section titled "Timing System," covering installation steps for the cylinder head cover (valve cover) and front engine accessories. Step 10 details installing the cylinder head cover: removing hardened sealant from the joint between the timing chain cover and cylinder head, applying Loctite 5900H sealant with a specified bead width of 2.5~0.5mm (0.098~0.019 in.), assembling within 5 minutes, and avoiding firing/blow-out tests within 30 minutes of assembly. Cylinder head cover bolts are tightened in two steps (Step 1: 3.9~5.9 N.m; Step 2: 7.8~9.8 N.m) following a numbered 18-bolt sequence diagram. A caution states the cylinder head cover gasket must not be reused. Steps 11–13 cover installing the crankshaft pulley (torque 166.7~176.5 N.m, using SST 09231-2M000 and 09231-2J210 to hold the crankshaft), the water pump pulley and idler (9.8~11.8 N.m and 53.9~63.7 N.m respectively), and the tensioner bracket assembly (39.2~44.1 N.m). Two diagrams (SBKEM6105D bolt sequence and SBKEM9102D front-of-engine component layout) illustrate the procedures. The page is undated but was uploaded for a 2010 Hyundai Genesis Coupe.

Frequently asked questions
- What are the torque specs for the cylinder head (valve) cover bolts?
- Tighten in two steps: Step 1 is 3.9~5.9 N.m (0.4~0.6 kgf.m, 2.9~4.3 lb-ft) and Step 2 is 7.8~9.8 N.m (0.8~1.0 kgf.m, 5.8~7.2 lb-ft), following the numbered sequence shown (bolts 1–18).
- What sealant is used on the cylinder head cover and what is the bead width?
- Loctite 5900H, applied with a bead width of 2.5~0.5mm (0.098~0.019 in.). The cover must be assembled within 5 minutes of applying sealant, and old hardened sealant between the timing chain cover and cylinder head must be removed first.
- What is the crankshaft pulley bolt torque?
- 166.7~176.5 N.m (17~18 kgf.m, 122.9~130.2 lb-ft). Fix the crankshaft using SST 09231-2M000 and 09231-2J210 when installing the crankshaft pulley bolt.
- Can the cylinder head cover gasket be reused?
- No. The document cautions: 'Do not reuse cylinder head cover gasket.'
- What are the torque specs for the water pump pulley, idler, and tensioner bracket?
- 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); Tensioner bracket assembly (A): 39.2~44.1 N.m (28.9~32.5 lb-ft).
