OK, I am at a bit of a loss here. I have seen three completely different torque specs for the 2009 L4-1.6 engine head bolts.
18 ft/lb+60+60+60+10 degrees
25NM+70+70+70+35 degrees
25NM+90+90+90+45 degrees

The last one is from the All Data Repair website for the car which supposedly is from the manufacturer service manual. However, it is MUCH higher than the other figures, so I suspect it.

Anyone have a service manual for the 2009 with the later VIN?

Thanks,
Keen
