🔍 Key Concepts

• Diesel engine cooling system and how coolant circulates around the cylinder head • What happens when combustion gases escape the combustion chamber into the cooling system • Typical signs of fuel vs. lube oil vs. coolant related problems

💭 Think About

• Think about where a cylinder head crack is most likely to leak to: fuel system, lube oil system, or cooling system? • If combustion gases are escaping through a crack, where would those gases show up and how might you detect them? • Which option directly involves the path between the combustion space and the cooling water, instead of just increased fluid use?

✅ Before You Answer

• Identify which choice involves the cooling system rather than the fuel or lube oil systems • Ask yourself which symptom would most clearly show gas or water transfer where it does not belong • Verify which option reflects a direct sign of combustion gases entering coolant, not just higher consumption of a fluid
