How to replace the catalytic converter on the LE5/L61 engine on 2008 Chevrolet HHR?

The initial step toward replacing the le5/l61 engine's Catalytic Converter requires suspension of the vehicle from the ground. You need to pull back the Muffler assembly while unscrewing the exhaust Muffler nuts so you can detach the Catalytic Converter from the Exhaust Manifold. Start by removing the specific engine-type post catalyst heated Oxygen Sensor (HO2S) followed by removing the Catalytic Converter nuts to extricate the converter from the Exhaust Manifold. Discard the gasket during this process. When installing the Catalytic Converter apply a new gasket to Exhaust Manifold studs before mounting it to the Exhaust Manifold with torque settings at 46 n.m (34 lb ft). After the engine-specific post catalyst ho2s replacement you should reinstall the part while reconnecting the Muffler assembly to the Catalytic Converter then finish the installation by tightening the exhaust Muffler nuts to 46 n.m (34 lb ft). Lower the vehicle carefully with a 3-degree limit on all directional bends to protect the exhaust flex decoupler.
