On 98 Honda Accord is it normal for the radiator to go at 138,000 miles?

What is your question?

My parents are planning to give me their 98 Honda Accord, and they just bought a new one. Yesterday when they turned on the A/C in the 98 Accord and drove it the engine temp went way above normal. Their mechanic is now replacing the radiator. Is this normal for an Accord at 138,000? Otherwise my parents have fully maintained the car. Just wondering how many more repairs are going to be needed.
