How to Add Fuel Injector Cleaner?
2 Answers
First, remove several fuel injectors, then separate them one by one and connect two wires to the terminals of the fuel injector. Remove all the sensors on top. Take a bottle of cleaner and connect a tube to the fuel inlet of the injector, then connect those two wires to the battery—one to the positive and one to the negative terminal. Remove the intake manifold.
Adding fuel injector cleaner is actually quite simple, and I often do it myself. First, wait until the fuel tank is about half empty so the additive mixes evenly. When opening the fuel cap, twist it slowly—don't rush to avoid accidents. Then, slowly pour in a bottle of cleaner, avoiding splashing or spilling to prevent staining or corroding the car body. After pouring, immediately fill the tank with gasoline to the full mark so the diluted cleaner won't damage parts due to high concentration. Drive for about 10-15 kilometers or half an hour to warm up the engine, allowing the injectors to be cleaned. I recommend choosing high-quality products—don't cheap out on inferior ones. Adding it periodically, say every 5,000 kilometers, helps prevent carbon buildup and improves performance. In summer, use a cleaner with good fluidity, and in winter, be careful to avoid fuel line freezing. Safety first—avoid fire hazards and read the instructions carefully.
