Peterbilt 389 Winter Fronts & Bug Screens

Frequently Asked Questions About Peterbilt 389 Winter Fronts & Bug Screens

What is the difference between a winter front and a bug screen?

A winter front is a solid or heavily insulated cover that mounts over the grille to block cold air from reaching the radiator and engine, helping the truck maintain proper operating temperature in cold climates. A bug screen is a mesh or perforated cover designed to keep insects, debris, and road grime from clogging the radiator core while still allowing airflow. Both mount in a similar location on the front of the truck but serve different purposes depending on the season and climate you are running in.

Will a winter front or bug screen fit my Peterbilt 389 without modification?

Most winter fronts and bug screens in this category are designed to match the factory grille shape and mounting points on the Peterbilt 389, so they typically install using existing hardware or grille features without cutting or drilling. That said, fitment can vary slightly depending on the specific grille style or model year on your truck, so it is a good idea to confirm the listed fitment details on each product page before ordering.

What materials are these covers made from, and how durable are they?

Winter fronts are commonly made from heavy duty vinyl, insulated fabric, or coated fiberglass, while bug screens are typically constructed from aluminum, stainless steel, or durable mesh material. These materials are chosen to hold up to road debris, temperature swings, and repeated on off use throughout the season, but like any exterior component, the lifespan will depend on how the truck is used and how well the cover is maintained.

How do I install and remove a winter front or bug screen?

Most winter fronts attach using snaps, straps, magnets, or ties that correspond to existing grille features, allowing drivers to put them on or take them off without special tools. Bug screens usually bolt or clip directly to the grille or bumper area for a more semi-permanent fit. Installation time is generally short, but we recommend reviewing the instructions included with your specific product since attachment methods can differ between styles.

Can I run a winter front all year, or should it be removed in warmer months?

Winter fronts are intended for cold weather use only. Leaving one on during warmer temperatures can restrict airflow to the radiator and cause the engine to run hotter than normal, which may lead to overheating. Most drivers remove the winter front once temperatures rise and either leave the grille open or switch to a bug screen for the warmer months when insects and debris become more of a concern.
