2002 Chevrolet Tracker Exhaust Manifold Parts Questions & Experts Answers

• Q: How to replace the exhaust manifold on a 1.6L engine on 2002 Chevrolet Tracker?

  A: The start of an Exhaust Manifold replacement on a 1.6l engine requires disconnecting the negative Battery Cable along with removing the electrical connection from the heated Oxygen Sensor (HO2S1). Three bolts along with two nuts and one upper Exhaust Manifold heat shield must be removed from the Exhaust Manifold. The mechanic should elevate the vehicle before removing two bolts and a nut and the Exhaust Manifold reinforcement bracket from both the Exhaust Manifold and engine block. Next, remove 2 bolts and the front pipe/three way catalytic converter (TWC) assembly from the Exhaust Manifold . Lower the vehicle and detach the 9 Exhaust Manifold nuts before removing the lift hook followed by pulling out the Exhaust Manifold with its gasket. Begin by lowering the Exhaust Manifold heat shield because the removal process requires the three bolts. This is followed by extraction of the heated oxygen (HO2S1) sensor from the Exhaust Manifold and the three way catalytic converter (TWC) front pipe gasket from the Exhaust Manifold . To mount the heated oxygen (HO2S1) sensor begin by placing it into the Exhaust Manifold while tightening it to 43 nm (32 ft. Lbs.). Fasten the lower Exhaust Manifold heat shield to the Exhaust Manifold through its 3 attachment bolts before tightening them to 10 nm (89 inch lbs.). Mount the new Exhaust Manifold Gasket along with the Exhaust Manifold by fastening 9 nuts at 23 nm torque (17 ft. Lbs. Torque). Support the vehicle before you install the front pipe/twc assembly with a new gasket onto the Exhaust Manifold while torquing 2 bolts to 50 nm (37 ft. Lbs.). Install Exhaust Manifold brackets to the Exhaust Manifold and engine block through 1 nut and 2 bolts reaching 54 nm (40 ft. Lbs.) and 50 nm (37 ft. Lbs.) torque limits respectively. Lower the vehicle and install the upper Exhaust Manifold heat shield over the Exhaust Manifold before fastening it with 2 nuts and 3 bolts at 10 nm (89 inch lbs.). The (HO2S1) electrical connector and negative Battery Cable must be connected while tightening the cable bolt to 15 nm (11 ft. Lbs.).
