LIQUI MOLY 400mL Pro-Line Diesel Intake System Cleaner - Effective Engine Deposit Removal

A mixture of cleaning agents for cleaning and maintaining intake manifold and throttle body of Diesel engines. Dissolves and removes deposits and contaminants, restores normal function of moving parts. Also ideally suited to clean intake valves of modern direct-injection engines. Regular use keeps the intake system in perfect working order and reduces repair costs. Safe with catalytic converters, EGR and DPF systems. Application: Suitable for use in all diesel engines, with or without turbochargers. Safe for use with catalytic converters and particulate filters (DPF). Note: Use only with the spray probe attached to the can! The pre-assembled spray head is only a transport lock. Specifically, for cleaning diesel engine intake systems. One Can (400 ml) is for one application. A preventive application every 12 months / 10,000 miles is recommended. 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 cleaner 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.

The LIQUI MOLY 400mL Pro-Line Diesel Intake System Cleaner is specially formulated to clean and maintain diesel engine intake systems, including intake manifolds, throttle bodies, intake valves, and EGR systems. This advanced mixture of cleaning agents dissolves and removes stubborn deposits and contaminants, restoring the proper function of moving parts and improving engine performance. Regular use of this cleaner helps keep your diesel engine running smoothly, reduces repair costs, and ensures optimal fuel efficiency. It is compatible with all diesel engines, whether naturally aspirated or turbocharged, and is safe for use with catalytic converters, EGR systems, and particulate filters (DPF).

To achieve the best results, attach the spray tube to the can before use, and remove the hose or pipe connected to the throttle housing to gain access. The engine should be running during application, with the ignition switch off and the air mass sensor disconnected if necessary. Maintaining a minimum engine speed of 2000 rpm, spray the cleaner in short bursts of 2-3 seconds while moving the nozzle back and forth across the intake opening. If deposits inside the intake manifold or EGR valve are excessive, a second can may be used for thorough cleaning. After completing the cleaning process, keep the engine idling at 2000 rpm for at least 20 seconds to ensure complete removal of residual cleaning fluid. Always avoid contact with painted surfaces and the air mass meter during application, and after cleaning, erase any stored fault codes for optimal engine operation.

This product is ideal for preventive maintenance, recommended every 12 months or after 10,000 miles. Its rapid cleaning action, ease of use, and ability to clean without dismantling make it a practical choice for maintaining diesel engines.
