Intercooler

Term from Automotive Maintenance industry explained for recruiters

An intercooler is an important cooling device found in turbocharged and supercharged vehicles. Think of it as a special radiator that helps cool down the air before it goes into the engine. When air is compressed by turbochargers or superchargers, it gets hot, and hot air isn't good for engine performance. The intercooler's job is to make this air cooler, which helps the engine produce more power and run more efficiently. You might also hear it called a "charge air cooler" or "aftercooler" in some job descriptions or resumes.

Example Interview Questions

Senior Level Questions

Q: How would you diagnose an intercooler system that's causing poor engine performance?

Expected Answer: A senior technician should describe a systematic approach including pressure testing, visual inspection for leaks, checking mounting points, and understanding how intercooler issues affect overall engine performance. They should also mention signs like boost leaks and temperature monitoring.

Q: What considerations are important when upgrading an intercooler system?

Expected Answer: Should discuss sizing requirements, flow characteristics, mounting location options, and how to ensure the upgrade matches the engine's needs. Should also mention the importance of proper piping and connections.

Mid Level Questions

Q: What are common intercooler maintenance procedures?

Expected Answer: Should explain regular inspection points, cleaning methods, pressure testing procedures, and how to check for damage or leaks. Should also mention the importance of proper mounting and connection checks.

Q: How do you identify a failing intercooler?

Expected Answer: Should discuss common symptoms like decreased performance, excessive smoke, higher intake temperatures, and visible damage or leaks. Should also mention diagnostic steps and testing procedures.

Junior Level Questions

Q: What is the basic function of an intercooler?

Expected Answer: Should explain that an intercooler cools down compressed air from the turbocharger or supercharger before it enters the engine, improving performance and efficiency.

Q: What are the basic parts of an intercooler system?

Expected Answer: Should identify main components like the core, end tanks, mounting brackets, and connecting pipes, explaining the basic function of each part.
