    The Cause
    The heater core was blocked with contamination which led to poor heater performance. The contamination was caused by a faulty water softener within the factory, which supplied the coolant filling machine with water contaminated with chloride. This results in a level of internal surface corrosion developing in the cooling system. The resulting corrosion blocks the heater core.

    Countermeasure at factory (Swindon)
    A reverse Osmosis unit has been fitted after the water softener process. In addition, conductivity sensors have been fitted which will detect a rise in chloride and shut off the water supply should equipment failure occur.

    Let this guide be a reminder to anyone never ever use tap water when mixing coolants! Chlorine will do that damage. Honda premix coolant is very safe and made from reverse Osmosis water.
