b. If your engine overheats within 20 miles of the end of your trip, you should complete the trip and then check the problem.
c. Antifreeze is not needed when the weather is warm.
d. You should never shut off an overheated engine until it cools.

Answer 1

The correct statement regarding engine overheating is that the radiator cap should never be removed on a pressurized system to avoid injury from hot steam or coolant.

Step-by-step explanation:

The student's question is about engine overheating and the correct practices associated with it. The true statement among the options given is a. You should never remove the radiator cap on a pressurized system. This is because removing the cap can cause hot coolant or steam to escape, possibly leading to severe burns. Options (b), (c), and (d) are incorrect and potentially dangerous.

Antifreeze serves more functions than just preventing freezing; it also raises the boiling point of the coolant and protects the engine. Overheating engines should be turned off to prevent further damage, and continuing to drive with an overheated engine can cause more harm. If an engine starts to overheat, it should be safely pulled over and turned off immediately.
