Nissan March 2000 what engine

Small cars have appropriate engines. And under the hood of the Nissan Micra fits a 1-liter naturally aspirated engine from the CG line, which is also represented by a 1.3-liter engine.

Despite its modest dimensions, the CG10DE is manufactured responsibly. 4 cylinders are located in a 16-valve BC made of aluminum. The timing chain is driven by 2 chains. This engine has an eastern variant. Both were produced in 1992-2003. Initially, the engine had a power of 54 hp. But after restyling in 2000, the power increased to 60 hp.

A detailed review and disassembly of the Nissan Micra 1.0 engine can be seen on our YouTube channel. The prototype was a motor from a car produced in 2001.

CG10DE engine reliability issues

In general, the Nissan Micra engine is reliable, although it also has its problem areas. Major breakdowns, as a rule, occur no earlier than after 20 years of operation and as a result of untimely maintenance.

Problems starting at low temperatures

This problem is typical for CG10DE even at temperatures close to zero. The problem can be solved by turning off the fuel pump before turning the ignition key by pulling the fuse from the control unit. The engine will start easily. After starting, the fuse is inserted back into the socket. And some car owners even install a separate toggle switch in the circuit.

Cleaning the idle speed control, which sometimes sticks, will also help start this engine in the cold. The procedure is simple and is carried out with the appropriate means.

One of the reasons for problems with starting in cold weather may be excessive restriction of the control unit's air supply during start-up. Flooded cylinders prevent the engine from starting. The most effective thing is to install additional resistance in the temperature sensor circuit. Then the information about the motor temperature is forcibly overestimated. The automaker even released a special cord. They connect the sensor and the control unit.

It happens that the CG10DE does not start when moisture in the catalyst freezes at night if it is clogged, which tightly clogs the exhaust system.

Difficulties at normal temperatures

If the CG10DE does not start at any temperature, the cause may be a clogged fuel pump screen or injector.

On cars with automatic transmission, it happens that the engine does not even rotate the starter. The gear selector should be checked. After stopping the car, it may not reach the extreme position.

Leaks

The age of the CG10DEs in service today takes its toll on various seals. Oil can leak from under the valve cover, through the spark plug seals, pressure sensor, or timing cover. On non-modernized engines, leakage occurs through the distributor gasket. Oil clogs its optical sensor, causing the engine to stall when driving.

Generator

This motor does not have any particular problems with the generator, however, after long use the bearings wear out. Will need replacement.

Nissan March Engine Sizes - Size Charts

home ⇒ equipment ⇒ engines ⇒ nissan

Below are data on engine parameters for 146 different years of production.

The external dimensions of the engine include the following parameters:

• Length (L): the full length of the mechanism at the edges of the most protruding parts;
• Width (B): side width of the unit;
• Height (H): The height of the mechanism at the edges of the most protruding parts.

Important: in addition to the standard parameters (L, B, H), the engines of some models have additional ones; if such parameters are available, they will be additionally indicated in the table below.

Inner dimensions:

• The internal dimensions of a car engine include parameters such as crankshaft dimensions, cylinder diameter, and piston stroke.
• The diameter of a car engine cylinder is the diameter of the working sleeve (or liner) of the working chamber of the volumetric displacement of the unit.
• Important: the piston stroke of a car engine is the distance between the top and bottom dead centers of the piston, which is determined by the radius of the crankshaft crank.

The compact car Nissan March is sold under the name Nissan Micra in Europe, North America, Africa, the Middle East and Australia.

Clogged injectors

When the injectors are clogged, floating speed, tripping, and engine stopping when idling are observed. A symptom of faulty injectors is an increase in fuel consumption.

If one of the injectors is clogged, only three cylinders will operate at any speed. It is not difficult to understand which of the injectors does not inject fuel. The candles are switched off one by one. If, when one of them is turned off, the tripping does not change, then the corresponding injector is faulty.

You can select and purchase injectors for the Nissan engine on the used spare parts page.

Distributor

Problems with the distributor are mainly found on engines manufactured before 2000. The winding breaks through and the spark disappears. A complete replacement of the part is required.

Damper

The CG10DE throttle body is a complete unit with an idle speed regulator and a thermal valve with a fuel flow sensor. If the idle speed is floating or increased, it will need to be cleaned. When carrying out the procedure, you should pay special attention to the air sensor so as not to damage its thread.

Having returned the unit to its place, it is “trained” by a simple “game” with the ignition switch.

Thermostat

The thermostat on Nissan Micra engines can be conditionally classified as a consumable. It requires replacement every couple of years. An impending thermostat breakdown is indicated by jamming and freezing of the motor. The result may be overheating or cooling at increased speeds and, as a result, expensive repairs. The lid is sealed with sealant.

water pump

This CG10DE part can hardly be called ultra-reliable. It often malfunctions, which is manifested by noise and antifreeze leaks.

Timing chains

Chains are one of the CG10DE's main weaknesses due to their susceptibility to stretching. More often the lower one is stretched. Rattling sounds indicate stretching of the chains. And its consequence may be a decrease in engine power.

BC head

After many years of use of the CG10DE, the oil seals become hardened. The oil burns more intensely, settling on the valves. Heat dissipation deteriorates and valves may burn out. The BC head often cracks during long-term use.

How much oil to pour into the Nissan March engine

Third generation K12, 2002-2010

The third generation March was designed in collaboration with Renault. Unlike previous models, the exterior of the new March was dominated by rounded shapes from all angles. In the original retro style, there was a place for bulging headlights, which delighted the world community even at the premiere. In addition to external changes, the developers have made improvements to the design. Thus, by lengthening the platform, developed jointly with Renault, the wheelbase was stretched by 70 mm.

The main feature of the new layout was the forward-moving cabin with record capacity compared to its classmates. Due to the high and wide body, it was possible to competently arrange the interior space, in which new options and comfort elements appeared. So, depending on the configuration, the hatchback began to be equipped with an on-board computer, a rain sensor and an electronic ignition key. There were also quite a few small storage compartments in the cabin, including a “secret” compartment under the front passenger seat. In terms of safety, the March was on par with its competitors, with four stars (out of five) for adult occupant protection in the EuroNCAP crash test.

Valve adjustment

Due to the lack of hydraulic compensators in the CG10DE, periodic checking of valve clearances and their adjustment is required. Often, when diagnosing problems with the motor, clearances are not given due attention. But when they increase at high speeds, a drop in engine power is observed.

The valves are adjusted using washers of 50 sizes.

Increased oil consumption

The problem occurs due to a clogged crankcase ventilation system valve or oil scraper rings.

Oil consumption can be normalized by decoking them or replacing the ring in CG10DE of the same repair size.

We disassemble the Nissan Micra 1.0 (CG10DE) engine

A tiny car needs a tiny engine. Namely a 1-liter naturally aspirated unit. This engine belongs to the CG family, which in addition to it also has a 1.3-liter engine.

With its tiny displacement, this engine is seriously built. It has 4 cylinders in line, an aluminum cylinder block, 16 valves. The timing drive is carried out by two chains. The 1-liter CG10DE engine was created for installation on the Nissan Micra and its eastern clone March 2nd generation, produced from 1992 to 2003. This engine develops 54 hp. or 60 hp The increase in power appeared after a slight modernization in 2000, when the compression ratio was slightly increased and an ignition system with individual coils was used.

On our YouTube channel you can watch a disassembly of the CG10DE engine removed from a 2001 Nissan Micra.

Nissan Micra 1.0 (CG10DE) engine reliability

Nissan's subcompact engine is quite good and reliable, but it does have some weaknesses. Serious mechanical failures are also possible, but mainly as a result of at least 20 years of use and poor maintenance.

Doesn't start in cold weather

The CG10DE engine has an unpleasant feature - it does not start in cold weather. Starting problems begin already at near-zero temperatures. They say that the most effective way in this case is to turn off the fuel pump before starting the engine. This is done quite simply: by removing the fuse from the block, which is accessible from the passenger compartment. The engine will start normally if the spark plugs were not flooded during unsuccessful cranking. When the engine starts, the fuse is returned to its place. Some people put a switch in the fuel pump circuit.

Another way to revive a 1-liter Nissan Micra engine in cold weather is to clean the idle air control. It happens that it jams and does not open at the time of startup. The regulator can be easily removed and cleaned with a suitable product.

There is also information that there are problems with starting the CG10DE engine in cold weather; the control unit overly restricts the air supply at the time of start-up, floods the cylinders with fuel, as a result the engine literally cannot breathe and it does not start. To eliminate this problem, a decoy is installed in the antifreeze temperature sensor circuit - an additional resistance that artificially increases the engine temperature data. There is even an original cable from Nissan with a 25 KOhm resistor that easily connects between the coolant temperature sensor and the ECU.

Another reason why the CG10DE engine does not start in cold weather is a clogged catalyst, in which moisture also freezes overnight, which finally clogs the exhaust system.

Won't start in warm weather

If the Nissan Micra (CG10DE) engine does not start in any weather, then you need to check the fuel pump - it is possible that its strainer is clogged. Clogged injectors could also be the culprit. And if the Nissan Micra engine with automatic transmission does not even turn with the starter, then the problem may be in the “automatic” selector, which does not go into the extreme position in “parking”.

Oil leaks

All CG10DE engines remaining in operation are no longer young, so they suffer from oil leaks at various seals: from under the valve cover, at the spark plug well seals, as well as at the oil pressure sensor, and at the timing cover. On the pre-restyling version, the distributor gasket leaks, because of this it gets on the optical sensor of the distributor, and as a result of this, the engine may stall while driving.

Generator

The CG10DE engine generator serves well, but with high mileage it may be necessary to replace the bearings.

Injectors

The injectors may become clogged and cause poor fuel atomization. In this case, such common symptoms as floating speed, trimming, and the engine may stall at idle. More accurately, problems with injectors are indicated by increased fuel consumption.

And if one of the injectors stops injecting fuel altogether, then the engine starts running on three cylinders throughout the entire speed range. You can identify a faulty injector in the standard way: by removing the chips or coils from the spark plugs one by one. If you disconnect a spark plug with a faulty injector, the nature of the engine's vibration will not change in any way.

Distributor

On pre-restyling CG10DE engines, the distributor fails - it breaks through the winding, causing the spark to disappear. The distributor is not repaired, but replaced with a serviceable new or used one.

Throttle valve

The throttle body of the CG10DE engine is a large unit with an idle speed control, thermal valve and mass fuel flow sensor in it. When cleaning the damper, you need to be very careful with the air flow sensor - the jet of cleaner will break its thread. Cleaning the damper is necessary in case of floating or high idle speeds.

After installing the removed damper, you need to train it, which is done simply by manipulating the ignition switch.

Thermostat

The thermostat on the CG10DE engine is almost a consumable and breaks down every few years. It freezes and jams, as a result the engine either does not warm up, cools down at high speed, or may overheat, which will lead to serious repairs. The thermostat cover is sealed with sealant.

Pump The reliability of the pump is also quite average. When it fails, it begins to make noise and leak antifreeze.

Timing chains

Timing chains are the weak point of the CG10DE engine. They stretch, especially the lower longer chain. When the chains are stretched, they rattle and problems with the gas distribution occur, which is felt by reduced engine power.

cylinder head

At high mileage on the CG10DE engine, the oil seals become tanned, which is why the oil starts to be wasted. Against this background, oil that burns and settles on the valves impairs heat dissipation, which can lead to burnout of one or more valves. Cracks may also appear in the cylinder head.

Valve adjustment The CG10DE engine is not equipped with hydraulic compensators and needs to be checked for valve clearances and adjusted if necessary. Usually, when any problems occur with the engine, the valve clearances are checked last - they are simply forgotten about. And if the intake valve clearances are “gone,” then the engine pulls poorly, which is mainly felt under high loads, during acceleration, for example.

To adjust the valves, you need to select shims and install them. The manufacturer has provided 50 sizes of washers.

Oil burns A few more possible reasons for the oil consumption of the CG10DE engine are a clogged crankcase ventilation system. As usually happens, the valve of this system becomes clogged.

Also, strong pressure of crankcase gases occurs due to the occurrence of oil scraper rings or wear of the cylinders. Oil burns can be cured by decoking or replacing the piston rings. The manufacturer has provided one repair ring size for this engine.

Reviews

Diana, Tver. The March hatchback is not ideal, but it is a balanced car for the city. My package has everything you need to comfortably get to work and back home. Model produced in 2004, version with a 1.2-liter engine and automatic transmission. Driving fast with such a combination, you know, is impossible even in your dreams. But you can save on gasoline, but you can also switch to gas. My copy eats 8-9 liters of AI-92 per hundred.

Larisa, Krasnoyarsk. I have a 2008 March, a restyled version with external and internal “new things”. Nothing special, the developers just added options and embellished the exterior. Of course, this didn’t make March any better, but it did give him a more current look. The 1.2 engine, in my opinion, is the most popular, that’s why I took it with an automatic transmission.
