15.2 Engine

15.2. Engine Since 1988, engines have been fitted with a 12-valve cylinder head. The design difference of the head is that there are three valves for each cylinder (two inlet and one outlet).

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

There were three body types of this series (however, as in all other series, for the station wagon body that appeared in April 1989 in the Mazda 626 serial line goes under a separate name - GV). A 4-door sedan, a five-door hatchback and a two-door coupe were available in different trim levels. Buyers were offered two configuration options - DX and LX. This version of the 626 lasted 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 the power supply system. So, in the FE series from 1983 to 1987. produced two-liter carburetor engines without a catalyst with a capacity of 101 hp. (index 2000 / FE). In 1986, the FE index was supplemented by a turbocharged injection engine 2.0i (FE-EGI) with a catalyst and an output of 120 hp, which was put on the five-door GT versions.

The next year, 1987, the Mazda 626 GC also began to install two-liter 12- and 16-valve injection engines with a capacity of 109 and 148 hp, respectively, and carburetor eight and twelve-valve catalyst "girls" with a capacity of 90 and 103 hp. respectively. On an eight-valve injection engine with a capacity of 90 hp. the catalyst was not installed. All this family went under the FE designation. In addition to 2.0 engines, the GC was equipped with engines of the old (since 1983) F6 index with a volume of 1.6 liters (1587 cc), with a capacity of 80 hp. Diesel engines were also installed on the GC. These were 2.0 liter RF engines. (1998 cc), 60 hp. Naturally, many of the engines in these series "moved" to the next 626 series.

Repair and maintenance of Mazda 626. Mazda 626 (from 1991 to 1998 of release)

Models of the fourth generation were just as radically different from the models of the third, as the latter were from the first. These were brand new cars.

Both the coupe and the sedan were built on a 261 cm wheelbase, although the sedan was 7 cm longer than the coupe model. The standard engine for both cars was a 2.0-liter DOHC with 118 hp. The only alternative was the 2.5-liter DOHC V6 164 hp engine. It was possible to install the same 5-speed manual or 4-speed automatic transmission. The 1993 626 was offered in the following variants: Basic DX, Basic LX and Ultimate ES; the MX-6 was introduced in base and LS versions.

Critics of the time noted not only the car's ability to quickly pick up speed and its agility. Everyone also noticed that it moves softly, and you can control it without much effort.

The new 626 and MX-6 models were radically different from their predecessors, but the MX-6 was contoured more proportionally than the sedan. The MX-6 is Mazda's first truly beautiful car. True, the "flying" outlines of the MX-6 limited the interior space - the back seat of the sedan was more spacious. The interiors of both cars were designed and executed flawlessly - every new detail was received with delight by the public.

In 1994, side airbags were added to the list of standard equipment on the 626 and MX-6 - by that time a driver's airbag had already been integrated into the steering wheel. The 626 LX could now be equipped not only with a 4-cylinder engine, but also with a V6. The 1995 626 and MX-6 were also produced without significant changes. The MX-6 LS variant was not produced - numerous components previously included in its package were offered as options.

In 1996, the MX-6 LS made a comeback with little change. The sedan is also almost unchanged - only its front fascia was decorated with a chrome strip.

The last representatives of the generation are the 1997 models. The rear spoiler, which was previously an option on the MX-6 LS, is now standard on this model.

By 1997, coupé cars were beginning to lose their popularity and Mazda concentrated on building the next generation 4-door sedan.

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

History of the car Mazda 626

In the secondary car market, it was the Mazda 626 that has always been the most popular. This trend has continued to this day, this car is considered the most successful model range of the eighties, for the entire existence of the brand. For all the years of production, the car came out in a variety of modifications, with different body options.

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

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

In general, the car gives the impression of being large, due to the large glass area. This car does not qualify for the title of an executive class car, it can rather be considered a good family car.

Despite the superior quality of Mazda vehicles, they are also prone to breakdowns. What is pleasant, the harsh weather conditions and the salt sprinkled on the Russian roads did not make these cars rusty, even those cars that were produced more than thirty years ago have no problems with the surface. The only exception is poor quality repairs.

Unfortunately, some other details, such as the exhaust system, do not deserve the same positive feedback. Breakdowns that concern the exhaust system of this model are so common that it would be high time for specialized service station workers to issue a separate repair manual for Mazda 626. As a rule, the rear side of the muffler of this car does not live in Russia for more than three years.

Taking an original muffler is quite a ruinous event, because of this, the owners do not install original ones, or they take "donors" of other car brands. Here it is worth noting the following - the chassis and engines were once used by the Kia company.

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

You can find a lot of interesting, and most importantly useful information in books on cars, their structure, correct operation and repair. If you are the owner of a Mazda 626 car, then the Mazda 626 repair book will come in handy.

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

If you have already decided to undertake a major overhaul of your Mazda 626, then it is advisable to start with the "wiretapping" of the engine. Gasoline engines that are installed on a car can have either four or six cylinders.

Naturally, 4 engines are much more common. When buying a Mazda 626, it makes no sense to wait for some extraordinary dynamics, its engine is not intended for a sharp drive. But such cars have a lower price and more rational fuel consumption.

Suitable for city driving just right. The main problem of the engines that came out of the Mazda conveyor is the demand for the quality of the oil poured in. The oil should be of exceptionally high quality, and the most expensive. Do not even think about experimenting with oil, pouring in some cheap products, in order to save a penny, you can, on the contrary, "get" a round sum when repairing an engine.

It is also necessary to ensure that there are no additives, otherwise the hydraulic lifters will start tapping. In general, before buying a used Mazda 626, it is better to immediately listen to its engine in an unheated state, then the knocking of the compensators will be immediately heard.

It was not possible to find other unpleasant and annoying features during the operation of the Mazda 626. It must be remembered that periodically you should change the timing belt, as well as monitor the general condition of the car.

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