Turn off the entire vehicle and check the positive battery terminal. . I guess the contact isn't good there. . The generator load is directly connected to the battery terminal. There appears to be a fuse outside the outlet. . Maybe the internal ignition of the ACC car key is bad. . Check it out. . It doesn't matter if the hand lever is turned off while driving. . As long as the engine is still running (whether in gear or idling), the booster pump is also moving and manifold vacuum still exists (I guess not many people keep their foot on the accelerator when braking. p>
Haval Why are the interior lights, headlights, fog lights, turn signals and wipers of H3 turned off?
Car engine overhaul mainly includes valve replacement , pistons, cylinder liners or cylinder bore, grinding shafts, etc.nt to the standards of general 4S workshops. 4 components need to be replaced, namely pistons, piston rings, valves, valve seals, valve guides, crankshaft bushings, connecting rod bushings, timing belts and tensioners.
1. Review of these elements?
1. If the timing chain and tensioner need to be replaced, machining, reaming the lower sleeve, grinding. Shaft, cold press pipe and overhaul kit need to be replaced, front oil seal, rear oil seal, camshaft oil seal, oil pump, valve, etc. Sometimes it is necessary to replace external parts, such as clutch plates, etc. In short, it is necessary to replace all parts that are not secure in their installation. To repair the engine and ensure its performance
2. The mechanical part generally includes a set of intake and exhaust valves.ent, one set of piston rings, and one set of four cylinder liners (if it is a 4-cylinder engine) Two thrust plates and four pistons
3. (the pump blades are corroded or the water seal has water seepage), the upper and lower water pipes of the motor, the large iron circulation pipe, the small circulation pipe, the water pipe throttle valve water (needs to be replaced if it gets old and swells), thermostat, etc.;
The fuel part usually mainly includes the upper and lower oil rings of the injector and the filter gasoline; if the high voltage line is swelling or leaking, replace and the piston will catch fire; upper and lower injector oil rings and fuel filter;
4. Ignition Part: If the high voltage line is swollen or leaking, replace the piston. which will catch fire; /p>
5. The air intake part usually includes an air filter
6. Other auxiliary materials generally include antifreeze, engine oil, engine oil filter, detergent, engine metal; cleaner or almighty water;
7. Components to inspect generally include whether the cylinder head is corroded or uneven, crankshaft, camshaft, timing belt tensioner pulley, timing belt adjustment pulley, timing belt, outer belt of the engine. and the adjustment wheel, rocker arm or rocker arm shaft, if it is a hydraulic lifter, check the hydraulic lifter
8. Cooling system part: water pump (pump blades are corroded or water seal is leaking; ), engine upper and lower water pipes, large iron circulating water pipes, small rubber circulation hoses and throttle water lines (need to be replaced if wornnt aged and swollen);
9. The kit includes cylinder gaskets and various oil seals, valve cover gaskets, valve oil seals, gaskets, etc. ;
Engine overhaul project is a generally, it mainly includes engine overhaul, cylinder head surface machining, cylinder boring, water tank cleaning, valve grinding, cylinder liner insertion, piston pressing, oil circuit cleaning, engine maintenance, generator maintenance, etc.
2. Parts that must be replaced during engine overhaul
1. Valve oil seal set, a set of intake and exhaust valves, a set of plug rings and a set of cylinder liner with 4 tappets Two pieces, large and small tiles, 4 plugs,< /p>
2. The cooling system usually mainly consists of the water pump (the pump blades are corrodedor the hydraulic seal does not leak)
3. The upper and lower water pipes of the engine, the large circulation iron water pipe, the small circulation rubber pipe and the valve water pipe (need to be replaced if there is no aging or withdrawal
4. The fuel part usually includes the upper and lower oil rings of the fuel injector and the fuel filter
p>
5 The ignition part usually includes if the high level is high; -The tension line shows no shrinkage or leakage. If not, replace the spark plug. The air intake part usually mainly includes the air filter.
6. Other auxiliary materials: Antifreeze, engine oil; Corroded or irregular crankshaft, camshaft, reverse belt tensioner, reverse belt reset wheel, reverse belt, external engine belt and reset wheel, rocker arm or rocker arm shaft, if it is hydraulic lifter, please check the hydraulic lifter. includes cylinder seals and various oil seals, valve chamber cover gaskets, valve oil seals, gaskets, etc.
Hello, Haval H3 interior lights, headlights, fog lights, turn signals, wipers and power outages may be caused by the following possibilities:
Firstly, there is a quality problem. with the battery. It could be that the battery we used has been used too long and is getting old, causing a power outage. It is also possible that the battery itself is of poor quality or that its capacity is too low. You can check and replace the battery.
Second, there is a wiring problem caused by a broken fuse. You can also check the wiring of the entire vehicle.
Third, insufficient power causede by a generator failure. If the problem is caused by a generator failure, it is recommended to check, repair and replace it ~
Fourth, the voltage regulator block. is toasted. Same as a blown fuse, you can check it.
Finally, it is recommended to regularly check and maintain your vehicle to ensure safe driving.
Finally, I hope that my answer will be useful to you~ Have a nice trip~
