How to remove and install the oxygen sensor and exhaust manifold on 1.5 litre on Mitsubishi Lancer?

In the 1.5 litre versions, the oxygen sensor is fitted in the exhaust manifold whereas on the other versions, it is fitted in the engine pipe. To take off and put on you must first lift the front of the car, and support it securely on jack stands. Unplug the wiring of the oxygen sensor, remove the retaining bolts, and take the heat shield off the relevant manifold. Proceed to unscrew the nuts securing the engine pipe to the exhaust manifold, and lower down the engine pipe assembly. Support the engine pipe assembly with a piece of wire tied up to the centre member of the vehicle, so that the engine pipe is not left hanging unsupported. This may damage the flexible joint. After that, unfasten the nuts and washers that secure the exhaust manifold to the cylinder head. Then withdraw the exhaust manifold from the vehicle and discard the gasket. For installation, the condition of the mating surfaces and the exhaust manifold and the cylinder head should be checked and cleaned of old gasket. Examine the manifold face distortion with a straight edge and feeler gauge; if distortion exceeds 0.5 mm, the manifold is to be renewed. Inspect the condition of the studs in the cylinder head and replace any that are corroded or broken. Before installation, apply a small amount of Loctite Anti Seize paste or equivalent to the exhaust manifold and engine pipe retaining nuts' threads. Place a new gasket on the cylinder head without blocking any holes on it. Once everything is done, tighten the retaining nuts evenly to the specified torque and run the engine to check for leaks.

Mitsubishi Lancer Exhaust Manifold

The Mitsubishi Lancer Exhaust Manifold collects flow from each cylinder and directs it to the single outlet which connects the exhaust pipe. It is the first path for hot combustion gases. The Exhaust Manifold assembly is attached directly to the cylinder head with bolts and sealed by gaskets. Its purpose is to ensure a gas-tight barrier so that exhaust gases continue straight through the catalytic converter, muffler, and tailpipe without leaking into the cabin. Many Mitsubishi Lancer versions are made from cast iron, which is chosen for its strength and resistance to heat. However, there are also welded steel and stainless steel tube alternatives that connect to the head with a matching flange. Certain applications utilize a heat shield that prevents the transmission of radiant heat from adjacent components and restricts floor temperature within the cabin. Some layouts see the catalytic converter integrated into the manifold body, thereby shortening the length of exhaust gas that must be treated. Many units have a threaded port for fitting of an oxygen sensor that feeds exhaust-oxygen data to the engine control module. Due to the constant high thermal cycling of the Exhaust Manifold, cracks may develop. A failure of the Exhaust Manifold causes the air-fuel balance to be disturbed and lets harmful gases escape. Exhaust Manifold units that are reliable replacements, made to Mitsubishi specifications, restore correct sealing and exhaust flow for the Mitsubishi Lancer, in turn restoring the vehicle's performance, emissions control, and passenger safety without interrupting the smooth running of a Lancer.

OEM Exhaust Manifold can boast superior quality and long-term durability. Each part meets strict factory specs and passes careful checks in production.

Q: How to remove and install the oxygen sensor and exhaust manifold on 1.5 litre on Mitsubishi Lancer?
A:
In the 1.5 litre versions, the oxygen sensor is fitted in the exhaust manifold whereas on the other versions, it is fitted in the engine pipe. To take off and put on you must first lift the front of the car, and support it securely on jack stands. Unplug the wiring of the oxygen sensor, remove the retaining bolts, and take the heat shield off the relevant manifold. Proceed to unscrew the nuts securing the engine pipe to the exhaust manifold, and lower down the engine pipe assembly. Support the engine pipe assembly with a piece of wire tied up to the centre member of the vehicle, so that the engine pipe is not left hanging unsupported. This may damage the flexible joint. After that, unfasten the nuts and washers that secure the exhaust manifold to the Cylinder Head. Then withdraw the exhaust manifold from the vehicle and discard the gasket. For installation, the condition of the mating surfaces and the exhaust manifold and the cylinder head should be checked and cleaned of old gasket. Examine the manifold face distortion with a straight edge and feeler gauge; if distortion exceeds 0.5 mm, the manifold is to be renewed. Inspect the condition of the studs in the cylinder head and replace any that are corroded or broken. Before installation, apply a small amount of Loctite Anti Seize paste or equivalent to the exhaust manifold and engine pipe retaining nuts' threads. Place a new gasket on the cylinder head without blocking any holes on it. Once everything is done, tighten the retaining nuts evenly to the specified torque and run the engine to check for leaks.
