What are the common engine failures in Ford Rangers?

I just bought a used Ford Ranger and I'm worried about potential engine failures. What are some of the common issues I should be aware of and how can I prevent them?

Regularly check your oil levels and change it every 5,000 miles to prevent engine wear and damage.

Keep an eye on your coolant levels and flush the system every 50,000 miles to prevent overheating and potential head gasket issues.
