Great. Thanks for that.

It looks like there are several engines used in the Civic DX. The engine serial number is located on exhaust side of engine block, below cylinder head near bellhousing. The first 5 characters of engine serial number identify engine type. Please take note of your serial number before following instructions below, although the tightening sequence remains the same, the torque specs are different for each engine type in the Civic DX.

Here is a video to help you see how to use a torque wrench.
