There are multiple variations of this kit, and you do NOT get the 'reboot' shown in the listings image

Worked AMAZING to clean a loop that was neglected for a few months. Cleaned old dye, buildup, and just junk out fast, and without a fuss. Was able to bring temps back down, and make the pump work alot less. Hopfully I don't have to buy again, but if I do, I will without question.

Todo muy bien gracias, si limpia los radiadores y es fácil aplicacion

So far I've used the Rad Clean on 7 radiators from old to new. Originally, all of them were already flushed with distilled water or vinegar solution, until no particles came out. But after peeking thru the G1/4 port, I did not like how the end-tanks were still filthy on some of the radiators. Decided to give Rad Clean a shot. I followed the instructions, Rad that was once assumed clean, had all sorts of particles came out, Rad Clean was able to dislodge them from the interior surface. If there's any old coolant gunk, oxidation on copper/brass surface of the inside of the radiators, now they would be have fresh, bare surface. There are some who runs a pump & filter loop to clean their rads. You can run the rad clean solution in that setup too. But you haven't invested in such setup or even an ultrasonic cleaner. I am certain this is one of the top best ways to clean in less time. Highly recommended! Thanks for stocking this item & will definitely purchase more in the future.

Los "stop plug" de plastico son muy delicados de calidad media-baja. aun no agrego el refrigerante asi que solo puedo opinar que el limpiador de radiadores es bueno.
