Hi, Bill, (& List). Again, quoting from the Good Book, chapter 3, verses 39 -40: "SERVICING THE RADIATOR AND COOLING SYSTEM: CLEANING: Only clean, soft water filled to 1/1/4 inch (approximately) below the bottom of the filler neck , should be used in the radiator and the cooling system of the engine. Hard water will form a scale, not only in the radiator core, but in the engine block, as well. This scale or lime deposit causes hot spots within the engine and will plug the small passages of the radiator core. Dirty water will alsoclose the tubes in the core and restrict coolant flow, and in extreme cases, will ncollect in the engine and cause overheating and eventual engine failure". COOLING SYSTEM PROTECTORS: CAUTION: Cars equipped with air conditioning must use a glycol-base permanent type anti-freeze in the cooling system throughout the entire year. MAKE CERTAIN THAT COOLING SYSTEM IS SAFEGUARDED FOR A MINIMUM PROTECTION OF +20 DEGREES IN SUMMER. This precaution is necessary inasmuch as the air conditioner evaporator lies in close proximity to the heater core, which may cause coolant in heater core to freeze (!!!!!!!!!!!), if system is not protected.
