Does the cowling at bottom of windshield need to be sealed when is replaced?

Yes, the cowling at the bottom of the windshield (the area where the windshield meets the body of the car) needs to be properly sealed when it's replaced. A poor seal can lead to:

* Water leaks: This is the most common problem. Water can enter the cabin, causing damage to interior components, mold, and rust.

* Wind noise: A gap in the seal can allow wind to whistle through, creating annoying noise at higher speeds.

* Air leaks: This can affect the efficiency of your car's climate control system.

Therefore, using the correct sealant and applying it properly is crucial for a successful windshield replacement. The sealant isn't just a cosmetic detail; it's a critical part of the car's weatherproofing.
