What is the torque spec for the head bolts on a 2.5L engine? I am changing the head gasket and can not find the torque specs for the head bolts anywhere. If you could help me with this issue I would appreciate it greatly! Thank you.

Here is the instructions and some diagrams (below) to help you get the problem fixed.

Apply new engine oil to the threads and the seating surfaces of mounting bolts.

Tighten all bolts to 98.1 Nm (10 kg-m, 72 ft. Lbs.).
Completely loosen all bolts as shown in the figure.
Retighten all bolts to 34.3 - 44.1 Nm (3.5 - 4.4 kg-m, 26 - 32 ft. Lbs.).
Turn all bolts 75 - 80 degrees (target: 75 degrees) clockwise.

Please let us know if you need anything else to get the problem fixed.

Cheers, Ken
