As we all know, boil water containers after repeated use for some time, will be a thick layer, the hard scale formation on the inner wall surface. Tank engine, too, the heat generated by the engine at high speed water circulation system to the tank, and ensure the normal operation state of the engine by the water tank for cooling. Over time, the tank will bear on the inner wall of a thick layer of scale. When the scale deposits to a certain extent, it will cause the tank volume becomes smaller, the impact of cooling water circulation. Because of the poor thermal conductivity of the scale layer, can also cause deterioration of engine lubrication, mechanical overheating, can not maintain normal working gap between the linkage parts, the mechanical properties deteriorate, thereby reducing engine power and fuel consumption increases, and even affect working life. Thus, after a period of time to run after cars, once the engine cooling system cleaning is very necessary. This cleaning and maintenance can play a detergent, rust, rust, acid effect, cleaning rate of more than 85%. Operation is very simple: just "cleaning agent" was added to the tank, at car wash normal operation, after a few hours, let go of the wastewater in the tank, again adding new coolant or antifreeze can. Recommendation: such a cleaning and maintenance at least twice a year.

In Fall because lower temperatures so the tire need to replenish the tire pressure within the specified range, of course, check the tire is not scratched, or have no place to leak rolling tires. Because in autumn there is still a lot of rain, so check the tread is too shallow, if rain road skidding lines and too shallow, then easily make the car deviation, traffic accidents, in which case we must promptly replace the tire. Of course, the chassis should be noted, in particular, did not do to the car chassis rust treatment, excessive summer rain, rain is very susceptible to corrosion chassis, If there is corrosion on chassis, then to deal with in a timely manner, to avoid danger.

its diesel engine,manual,when i engage gear and drive of the car wont go above 25mph when im in neutral and press down on accelerater engine revs normal but restricted when in gear help.

It is hard to say for the problem, you'd better find a mechanics to check it.
