Cylinder Head Bolt Toque

[TurboRay]

Howdee.......Newbie here! Apologies for being a "Troll", BUT.......I'm unable to find the proper tightening specs for the TTY/TTA head bolts on my 2013 Sonic 1.4 turbo engine, I have all the special tools and I know the torquing "sequence" ~ but not the torque values. Soooo.........I've decided to consult the experts! I've seen TWO different values/procedures posted on various websites:

(1) 26 ft/lbs + 180°​

(2) 18 ft/lbs + 90° + 90° + 90° + 45°​

Do any of y'all know which ~ if either ~ is correct? TIA, Ray!!

THANX, LilRed! I don't recall where I got that OTHER head-torque sequence of 18 ft/lbs+90°+90°+90°+45°. Does that sound familiar? <shrug>

You're welcome! Not off the top of my head, maybe a 1.8 or another part of the engine.
