Is Throttle Body Cleaning Necessary?
1 Answers
Throttle body cleaning is necessary. The throttle body is a controllable valve that regulates the air entering the engine. Since the air contains dust and sand particles, impurities naturally accumulate on the throttle body surface as air passes through. Additionally, oil vapor from the crankcase combines with these impurities to form a black, greasy deposit layer. More detailed explanations are as follows: 1. A dirty throttle body can cause sluggish movement, allowing impurities to enter the engine along with the air, which affects normal gasoline combustion. 2. Throttle body cleaning should be performed every 20,000 to 40,000 kilometers. If the driving environment is harsh, the cleaning interval should be shortened. While maintenance is beneficial, excessive maintenance can cause irreversible damage to the vehicle. Over-cleaning the throttle body may lead to premature failure, as frequent cleaning gradually removes the special coating inside the throttle body chamber, making it more prone to grease buildup. This creates a vicious cycle, ultimately resulting in the throttle body's failure.
