How to Replace the Water Pump in a 1999 Mirage 1 5L
The Mirage is a subcompact car that Mitsubishi Motors made from 1978 to 2002. The 1999 model most often had a 4-cylinder 1.5-liter engine with multi-port fuel injection. The water pump in a 1999 Mitsubishi Mirage is located on the front of the engine block. You can access it from the top of the engine compartment.

Let the vehicle to sit overnight to ensure the engine and radiator fluid are cold.
2Disconnect the cable for the negative battery terminal with a socket wrench. Put a container under the radiator and open the radiator drain. Wait for the radiator fluid to drain into the container. Seal the container and replace the radiator drain plug.
3Remove the undercover for the engine with a socket wrench. Disconnect the bolt from the power steering hose and detach the hose. Remove the drive belts on the engine and support the engine with a floor jack. Disconnect the bracket for the engine mount.
4Disconnect the timing belt with a socket wrench. Remove the bracket for the power steering pump and the brace for the alternator with a socket wrench.
5Disconnect the mounting bolts for the water pump. Detach the water pump from the water inlet pipe. Remove the gasket from the water pump and discard it.
6Clean the gasket surfaces with a shop rag and wet the new O-ring with water. Place the O-ring into its groove on the water inlet pipe. Install the new water pump to the water inlet pipe and tighten its mounting bolts to 17 ft. lbs with a torque wrench. Complete the water pump installation by performing steps 2 and 3 in reverse order.
7Fill the radiator with coolant and connect the cable for the negative battery terminal with a socket wrench. Start the engine and allow it to idle until the thermostat opens. Allow the vehicle to cool and adjust the coolant level in the radiator to the correct level.

How to Replace the Oxygen Sensor on a Mitsubishi Mirage
The Mitsubishi Mirage has a single oxygen sensor located just behind the catalytic converter. Its job is to tell the cars computer what the contents of the exhaust gases are so that the computer can make the necessary adjustments to ensure the vehicle runs properly. When the car starts to idle rough, it may be time to replace the sensor. In this case, the project vehicle is a 2002 Mitsubishi Mirage, but the process is similar for other vehicles as well.

Raise up the front of the vehicle using the jack and set it on the jack stands. Make sure that the vehicle is solidly on the stands before crawling underneath it.
2Locate the oxygen sensor on the exhaust, which is just behind the catalytic converter, underneath the front seats. This will stick out perpendicularly from the tubing and have a wiring harness pigtail coming out of the end. Unplug the wiring harness from the oxygen sensor using by hand.
3Place the oxygen sensor socket onto the ratchet then put the socket onto the oxygen sensor so that the wiring from the sensor leads out of the hole in the side of the socket. Then loosen the oxygen sensor from the exhaust and discard it.
4Open up the container of anti-seize and use the provided applicator to apply the fluid onto the threaded area of the replacement sensor. Make sure you dont touch the end of the sensor with the fluid; otherwise, you risk fouling the sensor.
5Thread the replacement sensor into the threaded bung on the exhaust with manually to start, then tighten it in place using the 3/8-inch ratchet and the oxygen sensor socket. Plug the harnesses back together by hand.
6Raise the vehicle off of the jack stands and place it back on the ground using the jack.
