2008 Chevrolet Express 3500 Catalytic Converter Parts Questions & Experts Answers

  • Q: How to replace the catalytic converter on 4.8L and 5.3L engines on 2008 Chevrolet Express 3500?
    A: To replace the Catalytic Converter on engines of 4.8l and 5.3l, start by lifting the vehicle. Give the heated Oxygen Sensor (HO2S) electric connection a disconnect from the Catalytic Converter pipe, remove the Exhaust Hanger bolts and the hanger from the transmission. Next, remove the nuts and seals pegging to the junction where the Catalytic Converter pipe is attached to the exhaust manifolds, remove any flange nuts that hold the catalytic pipe to the Muffler. Carefully uninstall the Catalytic Converter from the vehicle and also remove oxygen sensors if necessary. To install, start to reinstall the oxygen sensors. Place the catalytic pipe and bolt the retaining nuts to the front of the Muffler but do not tighten the nuts. Replace seals, nuts and the Exhaust Pipe flange to Exhaust Manifold and to the Catalytic Converter to Muffler retaining nuts positioned to both 65 n.m (48 lb ft) and the Catalytic Converter to Muffler retaining nuts to 48 n.m (35 lb ft). Bolt back the ho2s electrical connections and attach the rest of the Exhaust Hanger and bolts to the transmission while tightening the bolts to 17 n.m (13 lb ft). Lastly, check the exhaust system for clearance and alignment of all the elements prior to lowering the vehicle.
