What should you watch for in the coolant and belts before hot-weather operation?
- A.Coolant type never matters
- B.Belts should be loose for summer
- C.Hoses only fail in winter
- D.Proper coolant level and condition, tight and uncracked belts, and hoses without soft spots, leaks, or swelling
Correct answer
D. Proper coolant level and condition, tight and uncracked belts, and hoses without soft spots, leaks, or swelling
Why
The cooling system fails in summer through neglected basics: a slipping or broken belt stops the fan and pump, and a soft hose can burst under pressure. The pre-trip check of belts, hoses, and coolant is the cheapest overheating insurance there is.
