What should you check about coolant before winter operation?
- A.That the antifreeze mixture provides protection to the lowest expected temperature and the level and hoses are sound
- B.That the coolant is pure water for better cooling
- C.That color alone proves protection
- D.Coolant checks matter only in summer
Correct answer
A. That the antifreeze mixture provides protection to the lowest expected temperature and the level and hoses are sound
Why
Antifreeze both raises the boiling point and lowers the freezing point; a weak mixture can freeze and crack major components. Testing the mixture strength, not just topping off the level, is the meaningful winter check.
