Questions and answers
What type of cooling fluid should I use for the Whisper 6
The recommended cooling fluid for the Mastervolt Whisper 6 is a cooling liquid marketed for use in combustion engines. It should protect against frost to -77°F (-25°C) and corrosion. Clean fresh water with antifreeze can be used if cooling liquid is not available, but the correct antifreeze mixture must be calculated according to the supplier’s instructions.
