The design and principle of operation of the Renault Symbol generator. Renault Symbol drive belt diagram - and replacement instructions.
Any car generator consists of the following components:
- housings with two covers;
- rotor/stator;
- brush group;
- diode bridge (rectifier);
- voltage regulator;
- drive part (pulleys, rollers, belt).
The principle of its operation is quite simple: when the rotor rotates, excitation occurs in its winding, which leads to the generation of a magnetic field. The stator converts this magnetic field into alternating current, the diode bridge converts alternating current into direct current, and the voltage regulator checks the stability of the generator output parameters regardless of the engine speed. Please note that when starting the engine, the operation of all vehicle systems, and especially the starting system, is provided by the battery, but as soon as the crankshaft speed reaches a certain value, the power circuit in the battery switches to the alternator.
Signs of a stretched belt
Typically, the generator can always provide electricity to all consumers, as well as charge the battery. But if one of its nodes becomes unstable, the battery will no longer have electricity to keep the battery charged and it will eventually die. To prevent this from happening, it is necessary to monitor the condition of the generator, periodically checking the voltage level it supplies to the battery.
The appearance of a characteristic whistle from the engine compartment, especially when engine speed increases, may indicate a weakening of the generator drive belt tension. This is the first sign that the alternator is not running at full capacity, which means that over time there will be problems with the battery and engine draining. A broken belt can result in a power outage in the car, as well as failure or wear of other generator components.
Replacing the alternator belt on Renault Symbol

The belt clearance is checked by pressing with your finger. If the deflection is more than 10 mm, it should be tightened. By moving the tensioner roller, the functionality of the bearing is checked. There should be no signs of jerking, kicking, squealing or grabbing when sliding with your hand. Removal: installation is accompanied by the following operation:
- Disconnect the battery terminals, remove the air filter.
Removing the air filter
Unscrew the roller bolt
Replace tensioner pulley
Installing a new alternator belt
At the end of the work, the fastening of the generator, air conditioner, tension roller, and pulleys is checked, the rollers of which should turn easily.
If a whistle appears when starting the engine or when the car is moving, there is a direct suggestion to replace the alternator belt and tensioner pulley.
How to tension the Renault Symbol alternator belt
Insufficient belt tension causes the battery to be undercharged, accelerating belt wear. But too much voltage is unacceptable, since in this case the generator bearings wear out quickly. Typically, the belt deflection should be 1.0-1.5 cm when pressing the belt section between the generator pulleys and the crankshaft with a force of 100 N. If this value is greater, it is necessary to tighten the belt according to the following algorithm:
- loosen the generator mounting nuts (lower and upper);
- Turn the generator adjusting bolt clockwise as the generator moves away from the BC. To loosen the belt, turn it in the opposite direction;
- subsequently, it is necessary to turn the crankshaft 2 turns, also clockwise, by turning the pulley bolt;
- check the tension of the key with a dynamometer or manually;
- tighten the generator mounting bolts.
Please note that this work is easier to do from underneath the car, so it is best to place the car in a hole or raise the front end by removing the crankcase guard.
Which belt to choose for Renault Symbol
The manufacturer recommends installing only original belts (catalog number – 7700101261). This does not mean that it is necessary to follow these recommendations; the main condition is that the belt length matches. The size of the Renault Symbol alternator belt may vary depending on the vehicle configuration - for example, with air conditioning and power steering it will be longer (1750 mm), without them it will be shorter (1110 mm).
The main rule is that the manufacturer is a well-known company. Dayco or Gates belts may be recommended, it is highly recommended to install only 6 pieces of clothing.
And if you only managed to get the fifth groove, then on cars with air conditioning you need to leave the outer groove, located further from the engine, empty. On models without air conditioning - closest to the engine.
Tension using adjusting bolt
Adjustment with a bolt on a VAZ-2110
This method is more progressive and is used in most modern machines. It is based on the use of a special adjusting bolt , by turning which you can adjust the position of the generator relative to the engine. The algorithm of actions in this case will be as follows:
- loosen the generator, its upper and lower fastenings;
- Using the adjusting bolt, we change the position of the generator;
- fix and tighten the generator mount.
Renault Symbol oil change
Changing the oil in almost all Renault cars is carried out the same way. If the car is still under warranty that's one thing, but if the dealership's warranty period has long since expired, why pay for something you can do in your garage with minimal tools.
All you need is a tetrahedron, plenty of rags, hand gloves, new oil in the amount indicated in the filling volumes to operate the car, an oil filter and, if necessary, an O-ring on the drain plug.
Important! If you want to extend the life of the motor, replace it at the same time as flushing the deposits with flushing fluid. This will help clear the walls of sediment and metal debris.
Step-by-step instruction
- Warm up the engine to operating temperature and allow it to cool for 5-7 minutes. The oil awakens better and faster if it is not cold. However, the heat can burn you, so it's best to let the engine sit for a while.
- Open the filler neck of the cylinder block (we wake up there to fill the oil) and remove the dipstick. If oxygen is allowed to flow, the liquid will come out faster.
- We lift the car and put it on supports. A necessary step for easy access to the drain plug. You can also use a viewing hole or overpass.
- Unscrew the drain plug with a wrench. Remember that used oil will wake up hot, take precautions to avoid skin burns.
- We pour the waste into the prepared container. Do not pour extracts directly onto the ground!
- Unscrew the oil filter. If the filter is securely tightened, a special filter wrench may be required.
- We insert the new filter by lubricating its o-ring with oil and pouring some oil right into the middle to absorb it.
- We tighten the drain plug after checking the integrity of the washer located on its thread. If necessary, it must be replaced (sealing washer).
- We lower the car from the racks and use the dipstick to fill the empty engine with oil.
- After the full oil rises to the level of the center of the dipstick between the MIN and MAX marks, we wait 3-5 minutes. Then we warm up the engine for 5 minutes and measure the level again. As a rule, after the first heating the level drops and we add as much as we need.
Choosing engine oil
When it comes to large car manufacturers that have a good reputation and produce really good cars, try to fill only original oils and recommend it to your friends. Native lubricants are specially formulated for specific engines with specific characteristics. Although in some cases analogues may be superior to the original. In the case of Renault Symbol cars, follow the principle of using original compounds. The plant recommended the oils to Elf, which works closely with the French automaker and is the official supplier of motor oils for this company. Some car owners will say that official oils for Renault are too expensive, and the car itself belongs to the budget category. Therefore, there is no point in spending that kind of money. This is not entirely true. Elf oils have all the characteristics, additives and properties that optimize the performance of Renault engines. They passed all the necessary tests and laboratory tests.
The Renault Symbol model can have 4 types of engines:
- K4J;
- K7J;
- K4M;
- K7M.
They all work well with Elf synthetic motor oil. The oil is called Evolution 900 NF and has a viscosity index of 5W40. The car owner has the right to change the viscosity if he needs a special winter or summer oil or another all-season option. You should be careful with analogues. Alternative oils may have similar properties and characteristics, but will not ensure efficient operation of the French automaker's power units.
Several facts speak in favor of Elf brand oil:
- this oil is suitable for all drivers, regardless of their preferred driving style;
- these compositions have the necessary parameters, additives and characteristics that help increase engine life and increase the overhaul interval;
- Any alternative oils are considered experimental because there is no official guarantee that they will not damage the engine.
Renault Symbol owners say that the only limiting factor is the cost of the engine oil recommended by the manufacturer. Now such lubricant costs about 450 rubles per liter. Considering that for some engines you need to buy about 5 liters, the total cost is not that small. Some analogues are cheaper. But this does not mean that Renault puts its customers in strict limits by prohibiting the use of other motor oils. As analogues you can buy:
- Castrol;
- Lukoil;
- ZIC;
- Ravenol;
- Mobile 1;
- Liqui Moly and others
Buy strictly synthetic oils. Only in conditions of severe wear, when it is necessary to switch to more protective lubricants against engine wear, can high-quality semi-synthetic fluids be used. Without mineral oils. On it, Renault Symbol engines behave unpredictably, serious damage is possible, which will lead to a major overhaul of the engine. If you decide to replace the manufacturer's recommended oil with an alternative formulation, try to use the highest quality fluid that matches the engine specifications.
Original
Owners of Renault Symbol cars usually fill in Elf Evolution SXR 5W-40 or 5W-30 engine oil. The viscosity of the lubricant depends on the operating temperature. For example, 5W-40, 10W-40 or 10W-30 are recommended for all seasons (for year-round use), while in general in summer it is better to use SAE 20W-40 or 25W-50. If the car drives mainly in the cold season, then you should opt for winter oil 0W-40, 0W-30 or 5W-30.
Unoriginal
Owners of old Renault Symbol cars buy motor oils from well-known brands, for example, Mannol, Motul, Valvoline, Shell, Kixx, Lukoil, Castrol, etc. In addition, when choosing a suitable fluid, you should pay attention to important characteristics, including API approval.
This parameter is selected based on the engine type and year of manufacture of the car. For example, for the first generation Symbol gasoline, released in 1999, semi-synthetic all-season oil with API-SH and SAE 10W-30 parameters is suitable. For later model years - API-SL. For the second generation Symbol gasoline produced in 2008, semi-synthetic is also recommended for all seasons, but with parameters 10W-40 and API-SL. For 2012 cars, you can use semi-synthetic API-SM. Below are the best Renault Symbol motor oils.
Required volume
Once you have decided on the brand of motor oil for your Renault Symbol, you need to decide how much lubricant you need to change yourself. Some of the lubricant remains inside the system even after complete drainage. But this is the norm. There are no problems when mixed with new oil. However, if you are switching to a lubricant from another manufacturer, it is better to use a cleaning paste first. Here is the data on the average volume of engine oil, taking into account the filter, which also needs to be filled to about 50 before installation:
- The 16-valve 1.2-liter engine holds 4 liters of lubricant;
- a 1.4-liter 8-valve engine will require 3.1 liters of oil;
- if you have a 16V with a volume of 1.4 liters, then 4.8 liters of liquid will be useful;
- 4.8 liters are also needed in a 16-valve engine, but with a volume of 1.6 liters;
- when replaced, the only diesel power unit in the Renault Symbol engine line includes 4.6 liters, the engine itself has a volume of 1.5 liters.
The figure is approximate, but as close as possible to real indicators. It all depends on how well you follow the procedure and how much old mining can be drained.
First generation LB0C, 1999-2008
The Symbol compact sedan is a structural copy of the 1998 Clio sedan, so it had a controversial design with unimpressive proportions, especially in the rear with domed windows. During the 2001 restyling, the car received updated front and rear parts, due to which the appearance of the car radically changed. However, the interior has remained virtually unchanged. In 2004, another aesthetic restyling took place, and in 2006 the car received a solid look in the style of the new Clio. Thanks to the improvements made, the Symbol looked advantageous against the backdrop of the angular Renault Logan of the first generation. The car was equipped with 1.4 petrol engines (75-98 hp).
Gasoline engines 2002-2008
- 1.4 75 liters with. (K7J), oil volume - 3.3 liters, tolerance and viscosity: API-SH, SJ, SL; SAE 5W-40, 5W-30, 10W-30, 10W-40, 0W-30, 0W-40
- 1.4 98 liters together with. (K4J), oil volume - 4.8 liters, tolerance and viscosity: API-SH, SJ, SL; SAE 5W-40, 5W-30, 10W-30, 10W-40, 0W-30, 0W-40
Second generation LU01, 2008-2012
The second generation icon was built on the platform of its predecessor, but received a completely new design with correct proportions at the rear. At the same time, the developers managed to maintain the same body design, despite the dramatic changes in the front and rear. The interior also became tougher, and in terms of equipment the car was in no way inferior to the Renault Logan.
On the Russian market, the car was offered with 1.4-1.6 gasoline engines (98-102 hp), as well as a manual or automatic transmission. In other countries, economical versions were also offered with a 1.2-liter (75 hp) gasoline internal combustion engine, as well as a 1.5-liter diesel engine with 84 hp. The second symbol was produced in Argentina and Turkey until 2012.
Gasoline engines 2008-2012
- 1.4 98 liters together with. (K4J), oil volume - 4.8 liters, tolerance and viscosity: API-SL, SM; SAE 5W-40, 5W-30, 10W-30, 10W-40, 0W-30, 0W-40
- 1.6 102 liters together with. (K4M), oil volume - 4.8 liters, tolerance and viscosity: API-SL, SM; SAE 5W-40, 5W-30, 10W-30, 10W-40, 0W-30, 0W-40
Replacement frequency
Servicing any car begins with studying the official manual. Renault has adapted its models well to Russian weather conditions and road quality. However, the recommendations presented somehow do not coincide with the actual interval between engine oil changes. The manual states that on all engines installed on the Renault Symbol model, it is necessary to change the engine oil at intervals of 15 thousand kilometers. This interval is only relevant if the machine is used in moderate conditions, is not subjected to heavy loads and does not experience sudden temperature changes. The following points influence the reduction of the actual interval between replacements of the working fluid in Renault Symbol engines:
- frequent traffic jams from traffic lights to traffic lights;
- hot summers and very cold winters;
- driving at high engine speeds;
- low quality of spilled fuel;
- using motor oil that does not meet the manufacturer’s requirements;
- poor quality roads, etc.
Therefore, in fact, it turns out that on Renault Symbol cars the oil and oil filter are changed not every 15, but every 8-10 thousand kilometers. Most owners adhere to these indicators. Motorists note that if such a maintenance interval is observed and high-quality lubricants are used, Renault Symbol engines work well, there are no problems and it is possible to maintain the functionality of the power plant. In more aggressive operating conditions and in the case of a high mileage of the vehicle, accompanied by severe engine wear, the frequency can be reduced to 5-8 thousand kilometers.
