The car no matter at which stage of the phenomenon of oil spills are likely to occur. Oil spills are a precursor of the car failed, and so can not be taken lightly. Jinhua Jisheng Di Howe reminded owners, diagnostic trouble in the form of understanding of the the automotive oil spill six forms.
Silicone oil fan clutch understanding of special margin, most of the new cars oil spill is the bane left in the assembly, with the bad, and the component is not properly in place. Oil seal, oil pad cup like seals can not play the role of the dam. The old car leakage due to seal failure due to wear and tear or aging.
Oil spills is bound to have traces of oil, and here I start with the analysis of traces of oil, say traces of oil determination. We know that the automotive gasoline, oil, brake fluid, gear oil, help oil five general; I do not introduce the color and odor of gasoline. Oil was bronze, higher viscosity.
Attention to gasket role. Car stand for parts (such as the joint end faces, the gasket between the parts of each end cap, shell, hood pad, flat enamel cover) plays a leak-proof seal. Materials, production quality, and installation does not meet the technical specifications, and would not achieve a leak-proof seal, even accidents. Such as the sump or the valve cover, the contact area is large and difficult to compaction, thereby causing oil spills.
Regulations required the car all kinds of fastening nut tightening torque. Pressure is not too loose the tight gasket will leak; tight screw holes around the metal bumps or threaded tighten the slip will, in turn, caused by oil spills. In addition, oil pan drain plug If you do not tighten back to Pine shedding, likely to cause oil loss and subsequent engine damage accident "bush-burning axle".
Timely replacement of failed oil seal. Car moving set parts (such as oil seals, O-rings) due to improper installation, journal and seal edge heart deflection and dumped oil. Some oil seals used for a long time due to rubber aging and loss of elasticity. Found leakage should update.
To avoid the one-way valve, the vent valve is blocked. Caused by tank shell temperature, oil and gas fills the entire space, the emissions do not go out, the tank shell pressure increased oil consumption increases and shorten the replacement cycle. Engine ventilation system clogged, increasing the resistance to motion of the piston, so that the increase in fuel consumption. The air pressure difference inside and outside of the tank shell, sealed weakness often lead to oil spills. Therefore required to carry out regular inspections of vehicles, and clear, clean.
Proper settlement of all kinds of tubing joints sealed. Car union nut frequent disassembly, easy to slip the wire off the buckle and loose, cause oil leakage. Replacement the union nut grinding method to solve its cone seal, pressed the nut and solve sealing.
Avoid wheel thrown oil. Wheel hub bearing and cavity excessive grease, or oil seal assembly is wrong, bad quality and aging failure; the temperature brake frequently hub; dumped oil will cause the hub axle nut loose. So use "cavity lubrication method (ie the right amount of lubrication)" to clear the air vent.
The special margin silicone oil fan clutch reminder: should look around before moving the car, take a look at the lighting device has no damage, the body does not tilt, oil spills, leaks and other leaks; should check the appearance of the tire and the doors, engine compartment cover line management positions cover glass situation.
