Mitsubishi Libero engines

Station wagons are always quite popular. These are comfortable cars that help the driver solve a variety of tasks. If you want to buy a car with such a body, it makes sense to consider the Mitsubishi Libero, this is a great car from Japan. Let's consider in more detail its technical characteristics.

Model overview

Mitsubishi Libero production began in 1992, in 1995 it was restyled, new engines were added, but the cd2v body was left almost unchanged. The car proved to be a success despite being based on the outdated Lancer platform of the previous generation. In 2001, plans were announced to curtail production, the last cars of this model rolled off the assembly line in 2002. Accordingly, at this point in time, you can only buy a used car.

There is another important point - the car was produced only for the domestic market of Japan. We got only cars taken out by private individuals. As a result, all vehicles of this model have a right-hand drive layout.

Initially, drivers were offered cars with 5MKPP and 3AKPP. After restyling, the three-speed automatic transmission was replaced with a four-speed one. As a result, the throttle response of the machine has increased slightly.

Regarding the transmission, it is worth noting that initially only front-wheel drive cars were offered. Later, 4WD FULLTIME was added to the lineup. This transmission offered drivers four-wheel drive with a center differential. As a result, the car became more stable on bad roads.

Engine Specifications

For ten years, while the model was on the assembly line, it received several engine options. This made it possible to ensure the selection of suitable characteristics for each motorist. In the tables, you can compare the characteristics of all power units.

Service

Any Mitsubishi Libero engine must be properly and timely serviced. The manufacturer recommends visiting the service every 15 thousand kilometers. At each visit to the service, the following work is performed:

• Diagnostics;
• Oil and filter change.

Please note that it is important to choose the right lubricant. It is recommended to use synthetics or semi-synthetics marked:

• 5W-20;
• 5W-30;
• 10W-40.

The replacement of the timing drive according to the plan takes place at a mileage of 90 thousand kilometers. Sometimes repairs may be needed sooner.

Typical malfunctions

Lubrication leaks are often observed on ICE 4g15 1.5, the reason is the cylinder head gasket. It needs to be replaced. It is diagnosed by oil leaks on the engine, if there are none, the problem is the wear of the oil scraper rings, a major overhaul is needed. Also, a frequent problem on these engines is vibration, the internal combustion engine pillows are to blame. The only solution is to replace the motor mounts.

A carburetor can be used on the 4g13 engine, especially on the Mitsubishi Libero 1.3 of the first releases. If you have a similar version and the engine does not start, the jets are most likely clogged. Just clean them up.

The rest of the engines have standard flaws. All of them can bend the valve when the belt breaks. Also, on a run of 200-300 thousand kilometers, most likely the power plant will require a complete overhaul.

Complete repairs are expensive. If there is a task to save money, you can use the Subaru ef 12 contract engine. It fits perfectly in terms of mountings, and practically does not require any additional settings.

Which engines are more common

There are practically no statistics on the prevalence of motors in Russia. Cars were not delivered to our country officially. Therefore, it is impossible to say exactly which versions are more popular.

Modification with which motor to choose

If you look at the reviews of drivers, it is best to operate turbocharged Liberos. They have sufficient power, while having practically no special problems. The only exception is the turbocharged 4D68, here in winter there may be problems with starting.

It is also recommended, if possible, to purchase cars produced after restyling. Usually their suspension and other structural components are in better condition.
