* Car engine repair (sharing of car engine maintenance skills) Car engine is How to analyze trade seasonalitya carHeart, engine failure will directly affect the performance of the whole vehicle, and even lead to the scrapping of the vehicle, so it is very important for the maintenance of the car engine. Next, I will share some car engine maintenance tips. 1. Check the engine water temperature. If the engine water temperature is too high or too low, it will have an adverse effect on the engine. Therefore, the engine water temperature should be checked frequently. Normally, the water temperature should be kept at about 90℃. If the water temperature is too high, first check whether the radiator is blocked, and secondly, check whether the pump is working normally. If there is a problem with the water pump, it needs to be replaced. Two. Checking the oil is the guarantee of the normal operation of the engine, and the amount and quality of the oil must be checked regularly. If there is too little oil or the quality is poor, it will increase engine wear, and even lead to engine failure in serious cases.Therefore, the oil should be changed regularly, once every six months or once a year. The specific time can be formulated according to the usage and suggestions. 3. Replacing the air filter to ensure the normal operation of the engine at the source is actually to fight for a better time, and the same is true for replacing the air filter. Yellow or odor is a signal to replace the air filter. Owners with large bandwidth can replace the automatic cleaning air purifier to replace the air filter to further improve the air quality. Four. Reasonable selection of oil and fuel. In the maintenance of car engines, if the appropriate oil and fuel can be selected, the operating life of the engine can be greatly increased.
