15.2 Engine

15.2. Engine Engines of models since 1988 are equipped with a 12-valve cylinder head. The design difference of the head is that each cylinder has three valves (two inlet and one exhaust). The valves are driven through hydraulic valve clearance compensators, which eliminates the need for periodic adjustment of valve clearances. The basic maintenance and repair operations of the cylinder head remain the same, but there are also features that are given below...

15.5. Engine electrical equipment System for monitoring detonation combustion of fuel in turbocharged models The causes of detonation combustion of fuel are too early ignition and operation of the engine on fuel with a low octane number.

Detonation is characterized by a very high...

The first Mazda 626 appeared in 1979 on the American market. It was a tight one, with a 2.0-liter SOHC four-cylinder engine producing 75 hp. a rear-wheel drive car that Consumer Guide then called a "Cheap BMW."

There were three body types in this series (as well as in all other series, because the station wagon body, which appeared in April 1989 in the Mazda 626 production line, goes under a separate name - GV). IN different configurations walked 4 door sedan, a five-door hatchback and a two-door coupe. Buyers were offered two configuration options - DX and LX. This version of the 626 remained in production until 1987.

The engines installed on the GC series differ in index. The most common is FE. It included a whole family of 2-liter engines (more precisely, 1998 cc), differing in the number of valves and power supply system. So, in the FE series from 1983 to 1987. two-liter carburetor engines without a catalyst with a power of 101 hp were produced. (index 2000/FE). In 1986, the FE index was replenished with a 2.0i turbocharged injection engine (FE-EGI) with a catalyst and a power of 120 hp, installed on the five-door GT versions.

The following year, 1987, the Mazda 626 GC also began to be equipped with two-liter 12- and 16-valve injection engines with a power of 109 and 148 hp, respectively, and carburetor eight and twelve-valve catalyst “girls” with a power of 90 and 103 hp. respectively. To eight-valve injection engine 90 hp the catalyst was not installed. This entire family went under the FE index. In addition to the 2.0 engines, the GC was equipped with the old (since 1983) F6 engines with a volume of 1.6 liters (1587 cc) and a power of 80 hp. Diesels were also installed on the GC. These were RF engines with a volume of 2.0 liters. (1998 cc), 60 hp. Naturally, many of the engines from these series "moved" to the next 626 series.

The manual describes in detail the operation, maintenance and repair of Mazda 626 cars of two generations:
1992-1997 and 1997-2002 with all engine options.
Intended for car owners and service station workers.

Design, maintenance and repair of Mazda 323 / Familia / Protege

2WD & 4WD models 1998 - 2004 release with petrol engines VZ (1.3 l), ZL (1.5 l), ZM (1.6 l), FP (1.8 l) and FS (2.0 l).

The manual provides step-by-step descriptions of procedures for operation, repair and maintenance front-wheel drive and all-wheel drive Mazda 323 / Familia / Protege cars produced in 1998 - 2004, equipped with petrol engines VZ (1.3 l), ZL (1.5 l), ZM (1.6 l), FP (1.8 l ) and FS (2.0 l).

The Mazda 626 was developed and released back in 1979, since then it has gone through a large number of different upgrades and changes. Thanks to continuous improvement, this car and now it is very relevant and in demand, and among middle-class cars it is considered a sales leader.

History of the Mazda 626 car

In the used car market, it is the Mazda 626 that has always enjoyed the greatest popularity. This trend has continued to this day; this car is considered the most successful model range the eighties, for the entire existence of the brand. Over all the years of production, the car came in a variety of modifications, with different body options.

Both a practical station wagon and five-door hatchback, and, of course, the classic Mazda 626 sedan. Most of all these cars were created with front-wheel drive, but in some modifications there were also all-wheel drive vehicles, With rear wheels, which taxi. In Russia, there are not many such experiments; in our area you can only find front-wheel drive cars of this model.

Despite the fact that there are different body styles, all Mazda 626 have common features, which are mainly manifested in classical, one might even say Japanese, design.

In general, the car gives the impression of being large due to the large glass area. This car doesn't deserve to be called a car. executive class, it can rather be considered a good family car.

Despite the excellent quality of Mazda vehicles, they are also prone to breakdowns. What's nice is the harsh weather conditions and the salt they sprinkle Russian roads, have not caused these cars to rust, even those cars that were produced more than thirty years ago do not have problems with the coating. The only exception is poor-quality repairs.

Unfortunately, the same positive feedback Some other parts, such as the exhaust system, are not worthy. Failures that affect the exhaust system of this model are so common that it would be time for specialist service stations to issue a separate repair manual for the Mazda 626. As a rule, the rear side of the muffler of this car has not lived in Russia for more than three years.

Taking an original muffler is quite a ruinous undertaking, because of this, owners install non-original ones, or they take “donors” from other car brands. It is worth noting the following here - chassis and the engines were once used by Kia.

Mazda 626 spare parts are incomparably more expensive than Kia spare parts, you can take advantage of this, because the benefits in this case are very noticeable. At the same time, the quality of the products of both brands is almost identical.

A lot of interesting, and most importantly useful information you can learn from books devoted to cars, their structure, correct operation and repairs. If you are the owner of a Mazda 626, then the Mazda 626 repair book will be useful to you.

From it you can get background information about your car, and also get acquainted with practical advice motorists, which are based on their many years of experience.

If you have already decided to take on major renovation your Mazda 626, then it is advisable to start by “wiretapping” the engine. Gasoline engines that are installed in a car can have either four or six cylinders.

Naturally, 4 engines are much more common. When buying a Mazda 626, there is no point in expecting any extraordinary dynamics; its engine is not intended for sharp driving. But such cars have a lower price and more efficient fuel consumption.

Perfect for driving around the city. Main problem engines that came out of the Mazda assembly line are demanding on the quality of the oil being poured. The oil must be of exceptional quality and the most expensive. Don’t even think about experimenting with oil, filling in some cheap products in order to save pennies; on the contrary, you can end up with a tidy sum when repairing the engine.

It is also necessary to ensure that there are no additives, otherwise the hydraulic compensators will begin to tap. In general, before buying a used Mazda 626, it is better to immediately listen to its engine in a cold state, then the knocking of the expansion joints will be immediately audible.

It was not possible to detect any other unpleasant and annoying features during the operation of the Mazda 626. You need to remember that you should periodically change the timing belt, as well as monitor the general condition of the car.

Keep in mind that the operation and repair of a Mazda 626 requires some knowledge in the field of cars, so it is better to read the relevant literature immediately after purchase. After all, you see, it is always cheaper to foresee a breakdown than to fix it.
