Many cars today have plastic belly pans and undercovers protecting the underside of the vehicle. Most drivers don’t realize how important they actually are. In this episode of the Bumper to Bumper Podcast, Dave Riccio and Jon Riggle break down why these plastic shields exist, what happens when they’re missing, and how something as small as a $45 piece of plastic can cause major problems if ignored. For many vehicles, a missing splash shield, chin spoiler, or air dam can disrupt airflow and lead to engine overheating.From airflow management and engine cooling to protecting critical components from road debris, snow, and water, these underbody panels play a bigger role than most people think. Dave and Jon also share a real shop story where a car received cooling fans, a radiator, and even a head gasket, only to discover the overheating issue was caused by a missing chin spoiler. This is a perfect example of how a small missing underbody panel can lead to a misdiagnosed overheating problem.In This Episode We Cover:Why modern cars use belly pans and underbody shieldsHow missing splash shields or air dams can cause overheating issuesWhy manufacturers spend money adding these partsThe real reason some oil leaks never reach your drivewayHow parking over curbs damages underbody panelsWhy some shops struggle to reinstall them during serviceDon’t forget to like, subscribe, and turn on notifications so you never miss a new episode of the Bumper to Bumper Podcast.Powered by Tri-City Transmission & Auto Repair, Arizona’s Oldest Transmission Shop, Serving Tempe, Mesa, Chandler, Scottsdale, Phoenix, and Ahwatukee.
