Mitsubishi 4g32 engine

The first power unit of this family entered mass production in 1975. Its working volume reached 1850 cubic centimeters. After 5 years, a new version was developed. Its characteristic feature was mono-injection, 12 valves and turbocharging. The next step in development was the 8-valve engine of the injection variety, developed in 1984.

The mitsubishi 4g32 engine, designed for 8 valves and having a working volume of 1,6 liters, as well as front-wheel drive, was used in 1987 for installation on the sixth generation of the Mitsubishi Galant. Further, on its basis, modifications were developed that included the DOHS system. They had high power characteristics and caused less harm to the atmosphere.

In 1993, the power unit has undergone tangible changes. Modifications began to be produced in which the flywheel was attached to the crankshaft with 7 bolts. The motor was installed on many Japanese cars while it was in serial production.

Technical specifications

The engine has a number of technical features that determine its cost. These include:

1. The working volume is 1597 cubic centimeters.
2. Maximum power reaching 86 hp. With.
3. The number of cylinders, which is equal to 4 - m.
4. The fuel used, the role of which is played by gasoline AI - 92.
5. The cylinder diameter is 76,9 mm.
6. The number of valves on one cylinder, equal to 2 - m.
7. The compression ratio, which is equal to 8,5.
8. The piston stroke is 86 mm.
9. The number of root supports. There are 4 of them in total.
10. The working volume of the combustion chamber, reaching 46 cubic centimeters.
11. The engine resource is approximately 250000 km.

Some motorists have difficulty finding the engine number. They should be aware that the desired set of numbers may be located on a special panel located between the air conditioning compressor bracket and the manifold.

How reliable is an ICE?

The motor is able to withstand a long service life even in harsh conditions, if timely repairs and maintenance are carried out. To monitor the power unit most effectively, the motorist must be aware of the main problems, which include:

1. Clogged nozzles, which is a consequence of the use of low-quality gasoline. You can solve the problem by replacing or cleaning the part.
2. Excessive motor heating. A similar phenomenon occurs if the fan does not operate at full capacity or the cooling system has lost its tightness.
3. Vibration during cold start. The problem may be due to a malfunctioning temperature sensor that sends an incorrect signal to the processor.

Eliminating these faults does not take much time and is cheap, but if you do not pay attention to them, then in the future problems can lead to more serious problems, the solution of which will require tangible investments.

Maintainability

The mitsubishi 4g32 engine does not have a complex design, which facilitates repairs both at a specialized service station and in a private garage. With basic skills and some equipment, a motorist will be able to independently perform:

• HCB gasket replacement
• installation of new valve stem seals instead of failed ones,
• dismantling broken valves and installing serviceable parts.

There are types of repair operations that are best left to professionals, especially if there are no special skills. These include removal of the cylinder block for the purpose of overhaul, as well as procedures such as sleeve, boring or grinding of powertrain components.

An inexperienced motorist should not make a decision regarding the maintenance or repair of an internal combustion engine. If there is no knowledge, then it is better to entrust this issue to specialists involved in repairing motors for more than a dozen years.

What kind of oil to pour?

The right choice of lubricant will extend the life of the engine and stabilize its operation as much as possible. If we are talking about the mitsubishi 4g32 engine, then it is recommended to fill it with oil marked:

1. 15w40, which is a product made from minerals. Such a lubricant is recommended for use in engines with significant mileage. The freezing point is -30 degrees, which makes it possible to use the oil in the conditions of the Russian winter.
2. It is synthetic and is able to provide the power unit with stable operation over a long service life. The lubricant can be used regardless of the season and has good cleaning properties, resistance to evaporation and retains its performance even under extreme conditions.

It is necessary to choose oil depending on the operating conditions in which the engine operates.

What cars is it installed on?

The mitsubishi 4g32 engine is widely used. It is installed on machines such as:

1. Mitsubishi Celeste. It is a compact coupe that entered series production in 1975. The vehicle has average dynamic performance, and also has rear-wheel drive.
2. Mitsubishi COLT II, ​​which is a small car ideal for urban driving. The car is characterized by wide doorways, low thresholds, and a high roof.
3. Mitsubishi L 200. The vehicle is a pickup truck ideal for off-road driving. The machine is characterized by ease of operation and a lightweight rear axle.

Each car belongs to different classes, but they are united by a power unit that makes them powerful and reliable vehicles.
