When the cold car accelerates, the engine sounds like an air defense alarm. What is the reason?
Friends, analyze it. Friends, analyze it. This is really difficult. The main reason is that we can't do everything by ourselves. You can find a garage, even a roadside garage. The quick repair shop can do it for you. Just a little money. You don't have to do everything yourself. Sometimes you can't do it yourself, and then you have to spend more money to repair it. The result is not worth the loss, and the money saved is not necessarily better than that. 2.0 or 1.5T? 2.0, I read a post that day saying that the gas wheel rang. I don't know 1.5T mine is 20 142.0, and sometimes there is your voice when it starts. It's hard to say that the click must be the throttle sound. If it is the sound of throttle, you can clean the throttle. Fiat is an electronic economizer door that needs to be adjusted after cleaning. But it is also possible that the rubber band of an oil pickup in the oil pan is aging, and the sealing performance decreases when the car is cold, resulting in low oil pressure when the car is cold, so there is a problem. You are cold and hot now. Maybe the rubber band is broken. As long as you maintain the rubber band, you can replace it (4S shop price 3 yuan! ), but you must open the engine oil pan, replace the sealing strip (around 48 yuan), use sealant (around 34 yuan, the above price is 4S), work in 84 yuan, and of course the oil should be changed. This phenomenon generally occurs in 1.5 vehicles with a mileage of more than 80,000 kilometers. Look at you 1.2 million, then the analysis may be the problem. However, it is difficult to judge the cause of this abnormal engine noise, and it may also be the metal impact sound from knocking in the engine cylinder. It's best to go to 4S stores or specialty stores to check the correct drugs and save money. As for the whistle of the engine, do you mean when idling or accelerating, or all the time? Fiat car series is a high-speed engine, and when the vehicle accelerates, it will sound like a racing car. It is normal that the intake and exhaust noise suddenly increases due to the sudden increase of intake and exhaust volume during rapid acceleration. If this sound is made when the air conditioner is turned on, it may be mainly caused by the friction between the air conditioner belt and the belt tug. I can't hear you now, so it's really hard to judge. I'd better find a 4S shop or a special place to check and rest assured. @20 19
