Previously I had removed and cleaned my radiator by soaking and flushing, more than once, with water and brushing.
However the bike was still running hot, 4 bars, with the fan regularly cutting in way too much. I was on the verge of buying a new rad, not sure if they are still available new from BMW.
I saw this coil cleaner mentioned previously, G2G-FOAM, and decided to give it a go as a last resort.
I bought the G2G, removed the rad from the bike, and completely soaked it from the engine side using half the bottle. I decided to collect any debris, if any, into an old sheet.
I waited ten minutes then gently flushed the rad though. I reapplied G2G in the worse affected areas.
The results are incredible.
After drying out the collected material in the sun I was able to empty the contents of the sheet into a microwave tray 5"x 7". The results speak volumes.
Additionally, there was at least 5mm of debris/sediment in the flushed water that had passed through the sheet which I collected into several containers, all with considerable amounts of muck in the bottom.
After drying, the airline also blew out even more crud that I couldn’t collect.
The radiator is visibly cleaner through all the fins that were previously completely clogged.
The bike now runs consistently at two bars, occasionally three. The fan has not kicked in on my last few rides.
In summary this product has exceeded my expectations and saved the cost of a new radiator, £730.00, if available.
Cost of the coil cleaner….. £20.74 inc delivery and some elbow grease.
