Question

Quizplus · Accepted Answer

Technicians should avoid using tap water in cooling systems as it may contain minerals that can cause scaling and corrosion. Instead, they should use distilled water or a recommended coolant mixture. Waterless coolant (WC) and propylene glycol are acceptable choices for certain applications, but they are not always the best option.
