Self-repair of the Lada "Kalina" car will be successful if 3 factors are simultaneously observed. The first one - if there is a clear understanding of the car's structure and its principle of operation. The second - if there is a clearly defined fault and guidance for its elimination. Third - if all repair operations are performed accurately and in full.
It is necessary
- - a set of tools;
- - lift or observation pit;
- - fuel pressure gauge, oil pressure gauge;
- - compressor.
Instructions
Step 1
If the crankshaft does not rotate when you try to start the engine, clean and tighten the battery terminals. Measure its voltage and recharge if necessary. Check the electric circuit of the starter, its drive parts, the traction relay, the starter motor. Check the ignition switch. Inspect the flywheel ring gear for damage and wear.
Step 2
If, when trying to start the engine, the crankshaft rotates, but the engine itself does not start, check for the presence of fuel in the tank. After that, clean and tighten the battery terminals, measure its voltage and charge, if necessary. Check the tightness of the parts of the power supply system, the serviceability of the fuel module and the fuel pressure regulator. Examine the timing belt. Check the engine management system. Diagnose the electrical circuits of the ignition coils. Determine the serviceability of the crankshaft position sensor and its electrical circuit.
Step 3
If it is difficult to start a cold engine, check the battery charge level and electrolyte level in it, diagnose the power supply system, make sure that the coolant temperature sensor is in good working order, the fuel injectors are tight, and the engine management system is in good working order.
Step 4
If you experience difficulty when trying to start a warm engine, check the air filter. Clean, rinse and blow if necessary. Check the health of the power system. Clean and tighten the battery terminals and ground contact. Make sure the coolant temperature sensor is working. If it is defective, replace it.
Step 5
If the engine starts, but immediately stalls, check the connections of the ignition coils. Tighten the loosened ones, replace the damaged ones with new ones. Measure the pressure in the engine power supply system. If it is less than normal, repair the power system. Also make sure that the connection of the exhaust system parts is tight. Diagnose the ECM.
Step 6
If oil stains appear under the engine, check the oil pan gasket for leaks and replace it if necessary. Tighten the oil drain plug. Make sure that the seals of the emergency oil pressure sensor and the cylinder head cover are tight. If they are leaking, replace them with new ones. Also, inspect the crankshaft oil seals. Worn or damaged, remove and install good ones.
Step 7
If the idle speed is unstable, first check the vacuum hose connections. They must have a tight and air-tight fit on the fittings. Find out if the air filter is clogged. Clean it if necessary. Measure the fuel pressure in the fuel supply system and make sure it is correct. In case of deviations from normal pressure, find and eliminate malfunctions in the power supply system. Make sure there is no damage to the cylinder head gasket. Replace the damaged one. Check the tension and adjust the timing belt. If the belt is worn, replace it. Also check the wear on the camshaft cams.
Step 8
If misfiring occurs at idle speed, make sure the spark plugs, high-voltage wires, ignition coil, fuel injectors are in good working order. Be sure to replace defective parts. Check the spark plug gap and adjust it. Check the tightness of the vacuum hose connections and the tightness of their seating on the unions. Use a compressor to measure the compression in all cylinders. The deviation of compression from the factory standards indicates the deterioration of the parts of the connecting rod-piston group and the valve mechanism.
