AUTOOL HTS558 Automotive Engine Inlet Valve Cleaning Machine, 220V Walnut Sand Carbon Cleaner with 18pcs Adapters(European Standard)

【Why Clean Carbon Deposits】Carbon deposits on the engine's intake ports and cylinders reduce engine power, increase fuel consumption, and cause the engine to shake violently when idling, which can seriously damage the engine. Therefore, we generally need to remove carbon deposits every 40,000 to 50,000 kilometres. 【Working Principle】AUTOOL HTS558 sandblasting equipment is a specialised machine for cleaning the engine's intake pipe and intake valve. Close the intake valve and spray nut powder into the engine intake through the air pump (not included), then the machine collects the nut powder by vacuum. After thousands of impacts, carbon deposits on the inner wall of the pipe are completely removed. 【Pure natural materials】Chemical cleaners corrode the hoses and shorten the service life of the engine. Walnut powder is a pure natural polishing material, its hardness is lower than that of metal but higher than that of carbon deposits, and it has high pressure and wear resistance. A large number of fine pores on the surface of walnut sand have excellent adsorption capacity, are non-toxic and corrosion-resistant. 【Advantages】High-precision engine systems are sensitive to foreign matter in the intake manifold. Therefore, we need AUTOOL HTS558 nut shell blasting machine to clean the carbon deposits in the intake manifold. Turn off the engine before cleaning, then turn the crankshaft to close the intake valve. AUTOOL HTS558 cleans one intake manifold at a time, so a six-cylinder engine must be cleaned 6 times (and so on). 【Note】AUTOOL HTS558 sandblaster is only suitable for cleaning the intake manifold and the back of the intake valve. If you want to clean the carbon deposits on the injector/throttle valve/cylinder, please choose AUTOOL CT150, AUTOOL CT200 or AUTOOL C100. The nut powder is not included in the package, please purchase it from the local market; a high-pressure air pump is required (not included).
