Nissan Terrano engine car problems.

Car Problems offers the information on the different modes facilitating repair and operation of the car. Today Car Problems tells about search of the reasons of Nissan Terrano engine car problems. When happens car problems with your car, it would be not necessary to clutch at the head and run behind the tool for this purpose that to a small screw to disassemble, and then anew to assemble your car. First of all it is necessary to define in what system failure - in electric, hydraulic, mechanical.
Search car problems your Nissan Terrano should be begun with the basic checks:
* check up an accumulator charge
* check up contact piece and possible corrosion of plugs of the accumulator
* check up wires going on a starter
* check up high-voltage wires and coils
* check up candles
* check up a cover distributor (to clean, dry if it is necessary and to check up integrity)
* check up a contamination of air and fuel filters
* check up vacuum hoses
* check up belts
* check up integrity of safety locks

The basic Nissans Terrano engine car problems are - impossibility of start-up of the engine, or its unstable work, and also car problems systems of a battery charging and the fuel or oil over-expenditure. Let's consider the reasons which саще all cause Nissan Terrano engine car problems.

1. The Nissan Terrano engine doesn't rotate at attempt to get
* the accumulator Is discharged
* Corrosion and a poor contact on accumulator plugs
* the Damaged starting circuits
* the starter (the involving relay or the engine if click from a pinion gear exit is audible) is faulty
* the ignition key nest Is faulty
* the Engine has wedged

2. The Nissan Terrano engine is turned, but not got (or is got hardly from a cold condition)
* car problems with the accumulator (especially if slow rotation of a bent shaft is audible)
* the fuel filter Has clogged
* car problems with a gasoline pump
* car problems with distributor, wires, the coil
* damp elements of the ignition system
* dead candles
* car problems with a belt or a chain (cam shaft)
* car problems with a low compression
* the carburetor or injectors has clogged
* the throttle is faulty
* water in fuel
* there is no fuel

3. The starter motor works, but doesn't turn the engine, or the starter motor rustles or is engaged hardly
* to wedge the pinion gear
* car problems with the involving relay of a starter
* a teeth of a pinion gear and (or) a flywheel is worn out, broken
* starter fastening bolts Are stirred up

4. The Nissan Terrano engine is got hardly from a hot condition
* the dirty air filter
* bad grounding of the engine
* stick a throttle
* problems with distributor

5. The Nissan Terrano engine is got, but immediately stops
* Problems with distributor, wires, coils
* Check up vacuum hoses and an intake manifold
* problems with a gasoline pump

6. The Nissan Terrano engine works non-uniformly on single turns
* Check up vacuum hoses and an intake manifold
* car problems with EGR and (or) PCV valves
* the air filter is choked up
* car problems with a gasoline pump
* car problems with the ignition system
* car problems with a throttle
* a blockage of the carburetor, an injector
* the layer pad of a head of cylinders is damaged
* the drivebelt or a chain or a camshaft is worn out
* clearance adjustment of valves (where there are no hydrocompensator bars) is necessary

7. The Nissan Terrano engine shoots on single turns, the engine "does not seize" on various speeds
* it is unequivocal, candles, distributor, wires
* plus from point 6

8. The engine stops
* it is unequivocal, candles, distributor, wires
* plus from point 6

9. Superfluous consumption of oil
* the case layer pad is damaged
* a front end cover layer pad
* a cover gasket of valves
* a front or rear epiploon of a bent shaft
* epiploons of valves (Oil-control caps)
* piston rings, buckets, cylinders - the major repair is necessary
* the stirred up oil filter

10. Superfluous consumption of fuel
* the air filter is choked up
* car problems with the ignition system
* car problems with a throttle
* a blockage of the carburetor, an injector
* a low pressure in tire covers, or their wrong size

11. The accumulator doesn't hold a charge, the gymnastics indicator doesn't die away
* the Bad belt tension of the generator
* Wires and accumulator plugs have corrosion, are stirred up
* the same but with generator wires
* the presence of short circuit leading to constant escape
* the faulty accumulator
* a faulty voltage adjuster
* the faulty generator

12. An overheat
* there is not enough antifreeze
* the thermostatically controlled chamber (as at overcooling)
* the radiator has clogged a dir.

Car problems - how to learn problems of the ignition system of the car?

Car Problems will tell about problems in the car ignition system. Car the ignition system carries out two basic functions:
* makes a spark and distributes it in a certain order and time between car spark plugs;
* increases pressure from the accumulator battery to size, sufficient for formations in a spacing of a spark plug of a spark.

There are many various types of ignition systems.

The majority of these systems can be it is placed in one of three groups: the conventional breaker point type ignition systems (in use since the early 1900s);

the electronic ignition systems (popular since the mid 70s);

and the distributorless ignition system (introduced in the mid 80s).

Car problems in the ignition system occur because of problems in performance specified before functions. The problem can arise at car start. You turn starting engine key in the ignition switch, hear a characteristic sound of a working starter, but the engine "does not shoot" and isn't started. If process to continue long time, the battery will be discharged also it it is necessary to charge. In this case, if it is known that the fuel delivery system is serviceable and in engine cylinders normal degree compression the car problem consists in absence of formation of a spark on candles ignitions.



Fig.1. Car problems: schematic of a typical conventional breaker-point ignition system.





For search of a problem of the car in the ignition system with a typical conventional breaker-point ignition system:
1. Be convinced that all spark plug cables of your car going from the accumulator battery to coil, from it to distributor and further to spark plugs have no problems in isolation, cracks, damages through which the electric circuit can become isolated on the car or engine case. Check up - whether there are problems with contacts no high-voltage wires of the ignition system of your car.
2. Check up - whether pressure on spark plugs arrives. For this purpose remove isolating cap from a candle and arrange it on distance about 5 mm from the engine case. Thus isolating cap it is necessary to fix ignition the tool. At at turning movement of a key of start and starter work between the contact piece located in a isolating cap and the engine case the spark should slip. If the spark isn't present - a problem of the ignition system of the car in coil or distributor.
3. If after test of a isolating cap you were convinced that in the ignition system there is no car problem it is necessary to check a spark plug. Turn out a spark plug and inspect it: on a candle insulator there should not be cracks and black stains, spark plug contact pieces should have a spacing of the established size, to be covered by dry touch of light brown or pink color (it specifies in correct installation of firing point and absence of hit of oil in the engine cylinder).Also to check up a spark plug it is possible (if other ignition system of the car has no problems) as follows: insert a candle in isolating cap and place so that the thread on a spark plug would contact to the engine case. Engage engine start. If thus in a candle the spark, a candle serviceable is observed.
4. The problem of the car ignition system can be in distributor.To check up as spark plug cables are densely inserted into a cover distributor; remove and inspect a cover - whether there are no on it cracks, whether pure contact pieces on its inside; inspect the gear distributor (are disconnected or not contact pieces at rotation a rotor distributor, whether a normal spacing between contact pieces when they are opened, whether the whole wire in a metal braid which connects disconnected contact pieces to the condenser).If in distributor isn't present problems, but at rotation a rotor distributor with the removed cover by means of engine start on dead contacts the candle isn't formed, the problem of the ignition system of the car in coil means.
5. The problem of the car ignition system can be in coil or in primary resistor.In a case of breakage they should be changed.
