My friend's GL1500 is running Warm... I suspect Scale Buildup, due to this new-to-him bike having sat for a long time.

Is there anything that can be added to the coolent, to disolve the scale? I'm thinking of using that "Mr Coffee" brand of cleaner, that works so well on my coffee maker. Any harm in that, or got something better?


ref: We've replaced the rubber hoses to the reserve tank; the radiator cap; and the coolent sensor.

There are some automotive ones on the market in which you drain all coolant, add chemical, run a while, drain and fill a couple times to clear the chemical, and refill the coolant.

Make sure anything you use is ok for aluminum engines. Also, some stuff made for cars might damage the water pump seal. Whatever you use, be sure to flush it completely out with DISTILLED water. Faucet water contains minerals and acids that will quickly start corrosion in an aluminum engine.
