Nissan GA15DS engine

The Nissan GA engine is a 1,3-liter, 4-cylinder gasoline internal combustion engine. It consists of a cast iron block and an aluminum cylinder head.

Depending on the model, it may have 12 valves (SOHC) or 16 valves (DOHC).

The engine was produced by Nissan from 1987 to 2013. Since 1998, it has been produced only for the Mexican automotive market.

The ancestor of the series was the classic GA15, which was soon replaced by the GA15DS.

Over the years, it was installed on different car models, so in the period from 1990 to 1993 - on the Nissan Sunny and Pulsar, from 1990 to 1996 - on the Nissan NX Coupe, from 1990 to 1997 - on the Nissan Wingroad Ad Van.

In 1993, it was replaced by the GA16DE, which featured an electronic fuel injection system.

Until 1995, the DS variant was installed only on European Nissan models, while Japanese cars had long had electronic fuel injection.

Engine name designations

Each engine has a serial number on the front side, which tells about its technical characteristics.

The first two letters in the engine name are its class (GA).

The numbers indicate its volume in deciliters.

The last initials indicate the method of fuel supply:

  • D - DOHC - engine with two camshafts in the cylinder head;
  • S - the presence of a carburetor;
  • E - electronic fuel injection.

The motor we are considering is called the GA15DS. From the name it follows that its volume is 1,5 liters, it has two camshafts and a carburetor.Nissan GA15DS engine

Power

The engine produces 94 horsepower at 6000 rpm.

Torque - 123 N at 3600 rpm.

Motors of the GA series are among the most unpretentious in use.

They do not require high quality fuel and oil.

Another distinctive feature of this internal combustion engine is the presence of two chains in the drive of the gas distribution system.

The drive is carried out through poppet pushers. There is no hydraulic lifter.

Operating tips and possible problems

Every 50 thousand km, oil, filters and candles must be changed. In addition, you should pay attention to the following details:

  • check and adjust valve clearances;
  • there may be problems with the idle valve (requires regular reading);
  • the mass air flow sensor (or lambda probe) may fail prematurely;
  • due to low-quality fuel, the strainer of the fuel dispenser may become clogged;
  • it is possible to increase oil consumption after 200 - 250 thousand kilometers, then replacement of oil scraper rings will be required.
  • after 200 thousand kilometers, it may be necessary to replace the timing chains (there are two of them in this engine).

In general, repairs and spare parts for this model will not cost you much. For example, the price of a starter on a GA15DS will be no more than 4000 rubles, a piston - 600-700 rubles, a set of candles - up to 1500 rubles.

The overhaul is estimated at 45 thousand rubles.

However, you must remember that this engine has not been produced for a long time and there may be problems finding qualified craftsmen for their repair and maintenance, as well as finding spare parts in the secondary market.

Results

The GA15DS engine is one of the most durable and reliable units and is not inferior in quality to its peers from manufacturers such as Toyota or Hyundai.

Easy to repair, unpretentious in operation, economical, eats very little oil. A small engine size implies gas consumption in the city of no more than 8-9 liters, depending on the driving style.Nissan GA15DS engine

The engine resource without overhaul will be more than 300 thousand kilometers. Using good gasoline and oil, this period can be extended to 500 thousand kilometers.
