LIQUI MOLY Pro-Line Throttle Valve Cleaner - 400mL

A mixture of cleaning agents for cleaning and maintaining intake manifold and throttle body of Gasoline engines. Dissolves and removes deposits and contaminants, restores normal function of moving parts. Also ideally suited to clean intake valves of modern GDI engines. Regular use keeps the intake system in perfect working order and reduces repair costs. Safe with catalytic converters, EGR and GPF systems.

To prepare, attach tube with nozzle. To gain access, remove hose or pipe immediately before throttle housing. The engine needs to run to perform cleaning. If unable to start engine, disconnect air mass sensor connector while the ignition switch is in off position. Maintain minimum engine speed of 2000 rpm while spraying cleainer in short intervals of 2-3 seconds, and at the same time move the nozzle back and forth across opening to completely treat intake tract. If engine speed fluctuates more than 1000 rpm stop spraying immediately and wait for speed to stabilize. Keep cleaning fluid from contacting air mass meter or painted surfaces. If excess deposits inside EGR valve, intake manifold or intake valves, a second can of cleaner may be used to improve the result. After completion, leave the engine running at 2000 rpm for a minimum 20 seconds to allow complete removal of any residing fluid in intake system. Afterwards erase any stored fault codes.
