How to Use Ceramic Paste on Fuel Injectors
Apply a small, thin layer of high-temperature ceramic paste to the injector body where it contacts the cylinder head, avoiding the nozzle, sealing surfaces, and electrical connections. The ceramic paste helps prevent the injector from seizing in the cylinder head, making future removal easier and protecting against corrosion. Always fit new seals where required and install the injector according to the vehicle manufacturer's specified torque settings.
