What is the 50,000-kilometer maintenance project of Corolla Twin Engine?

The 50,000 km maintenance project of Toyota Corolla of Pacific Auto Network mainly includes: replacing oil and oil filter, checking battery, brake pedal and parking brake, brake pad and disc, brake fluid, clutch fluid, tire and tire pressure, lights, speakers, wipers and sprinklers.

Under normal circumstances, when a car travels 60-80 thousand kilometers, it needs the first overhaul. It is recommended to replace the oil, mechanical filter, air filter and gasoline filter. Coolant, brake fluid, transmission gear oil, spark plug, steering assist oil. Clean throttle, fuel injector and three-way catalytic converter. Change the tire. Then check whether the chassis screws are tightened and the lighting is good and normal. Whether the tire is aging and cracked or whether the air pressure is normal. Whether the brake pads reach the wear limit. Whether the swing arm and pull rod ball head are loose. Whether the belt is cracked due to aging. The details are as follows: The first kind is very routine maintenance, such as changing some oil, mechanical filter of oil, air conditioner and air filter, but these also depend on the congestion of the car itself. If there is no performance, there is no need to change them. The second one is a spark plug. In a normal car, the life of the spark plug is 30,000 kilometers, and platinum is better, 60,000 to 80,000 kilometers. The naturally aspirated engine and spark plug of the original car are generally recommended to be replaced after 60,000 kilometers. Third, generally speaking, for manual replacement of 60,000 kilometers, the automatic transmission fluid should be opened to 6 to 800 meters wide. If it is in a first-tier city, the replacement time should be advanced. The fourth is brake oil. In fact, brake oil should be changed once every two years, which is easier to absorb. As long as the water absorption of brake oil exceeds 2%, it may not stop when braking. This should also be tested in a professional place. If it is within the normal range, there is no need to replace it. The fifth is the tire. The aging time of tires is generally five years, which is about 70 thousand kilometers. Therefore, it is necessary to check whether the tires have worn to the safety line at 60,000 kilometers. If it is worn to a certain extent, the tire will be replaced.
