Webinar: Cooling System Domino Effect-Why Replacing…

Cooling system problems rarely start and end with one component. Watch this webinar to see why this is the case.

Join ShopOwner and US Motor Works for a free webinar on Tuesday, September 15, 2026, at 2:00 PM ET. The webinar will run for 60 minutes.

During this webinar, you will learn how cooling system components work together. You will also learn what can happen when one component fails. More importantly, you will see why technicians should look at the entire cooling system before completing a repair.

What You’ll Learn

  • How cooling system components work together
  • Why one failed component can affect other parts
  • What problems can occur after a cooling system failure
  • Why replacing one part may not always fix the root problem
  • How a complete cooling system inspection can help prevent repeat repairs
  • What technicians should consider when diagnosing cooling system problems

In addition, the webinar will cover practical information that can help technicians make better repair decisions. You’ll gain a better understanding of the cooling system and the role each component plays.

Whether you work in a repair shop, manage a service department, or work with automotive cooling systems, this webinar can help you better understand the bigger picture.
