Was not able to find a Factory Service Manual for the 2009 Model KK online. But if the engine is the same as the 05-06 2.8 CRD engines, you can view the Factory Service Manuals for them which covers the instructions and torque sequences for the head bolt installation.
View Factory Manuals at:> https://www.colorado4wheel.com/manuals/Jeep/KJ/
Instructions start in Section No. 9, page 197 in the 2005 FSM. See Picture No. 1
PLEASE NOTE: Many owners opt to replace the problematic stretch to yield head bolts with ARP head studs which are NOT stretch to yield and are installed with simple torque figures rather than the complicated degree method used on factory head bolts. See Picture No. 2
