WARNING: This page is about a different car, the 2012 Ford Pickup, 2012 Ford F550 Super Duty, 2012 Ford F450 Super Duty, and 2012 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Do not tighten any fasteners until all components are aligned.
- With the help of an assistant, position the exhaust Y-pipe into the vehicle and loosely install 4 new exhaust Y-pipe-to-exhaust manifold nuts.
- Loosely install the 2 exhaust Y-pipe-to-catalytic converter bolts.
- To seat the LH exhaust Y-pipe-to-exhaust manifold nuts, tighten the nuts in the following sequence.
- Tighten the lower LH exhaust Y-pipe-to-exhaust manifold nut to 20 Nm (177 lb-in).
- Tighten the upper LH exhaust Y-pipe-to-exhaust manifold nut to 40 Nm (30 lb-ft).
- Tighten the lower LH exhaust Y-pipe-to-exhaust manifold nut to 40 Nm (30 lb-ft).
- To seat the RH exhaust Y-pipe-to-exhaust manifold nuts, tighten the nuts in the following sequence.
- Tighten the lower RH exhaust Y-pipe-to-exhaust manifold nut to 20 Nm (177 lb-in).
- Tighten the upper RH exhaust Y-pipe-to-exhaust manifold nut to 40 Nm (30 lb-ft).
- Tighten the lower RH exhaust Y-pipe-to-exhaust manifold nut to 40 Nm (30 lb-ft).
- Tighten the 2 exhaust Y-pipe-to-catalytic converter bolts.
- Tighten to 40 Nm (30 lb-ft).
- Connect the CMS electrical connector.
- Connect the 2 HO2S electrical connectors.
NOTE:
Prior to installation, inspect the Heated Oxygen Sensor (HO2S) and the Catalyst Monitor Sensor (CMS) wiring harness for damage.
NOTE:
LH exhaust Y-pipe-to-exhaust manifold shown in illustration, RH similar.
NOTE:
Make sure the exhaust Y-pipe is aligned to provide maximum clearance to adjacent parts.
