It cleans the radiator very well. I used full quantity and flushed with battery distilled water 3 times and radiator was cleaned completely.

Put it in my cooling system that was not producing heat. After 1 hour, I started to get heat again. Had the coolant system flushed and filled with excellent results. I would definitely recommend it! REMEMBER 2051 part #

I added this Liqui Moly radiator cleaner during a coolant flush on an older vehicle. The additive mixes quickly, and after letting the engine run, I could see the old coolant draining out with noticeably more debris than a water flush alone. The bottle is the right size for a single treatment, and the instructions are clear. After flushing and refilling with fresh coolant, the engine temperature held more consistently, especially during longer drives. Minor note: itโs important to run the heater while circulating the cleaner so it reaches the full system โ not really a con, just part of the process. For anyone doing DIY coolant maintenance, this helps get a more thorough clean.
