Frequently Asked Questions About International 9300/9370 Winter Fronts & Bug Screens

Will these winter fronts and bug screens fit my specific International 9300 or 9370 model year?

Most winter fronts and bug screens for International 9300/9370 trucks are designed to fit models from 1987 through 2007. However, there can be variations based on your specific grille configuration and whether you have a standard or extended hood. We recommend checking your truck's exact model year and measuring your grille opening (typically 42" wide x 24" tall for standard configurations) before ordering. If you're unsure, contact us with your VIN number and we can verify compatibility.

What materials are these winter fronts made from, and how well do they hold up in extreme cold?

Quality winter fronts are typically constructed from heavy-duty vinyl or marine-grade vinyl mesh that remains flexible down to -40 degrees Fahrenheit. The better options feature reinforced edges with heavy-duty binding and rust-resistant grommets. Look for materials rated at least 18-20 oz vinyl for maximum durability. The mesh bug screens usually feature powder-coated aluminum or stainless steel frames with UV-resistant mesh that won't become brittle in cold weather.

How difficult is the installation, and what tools will I need?

Installation typically takes 15-30 minutes and requires no drilling or permanent modifications. Most winter fronts attach using the existing grille mounting points with included bungee cords, heavy-duty snaps, or quick-release clips. You'll need basic hand tools like pliers for tightening clips. Bug screens often use a simple tension-mount system or clip directly onto the grille frame. The main challenge is ensuring proper tension to prevent flapping at highway speeds.

What's the difference between a full winter front and a partial coverage option?

Full winter fronts cover the entire grille opening and are ideal for extreme cold conditions (below 20 degrees F) to help maintain optimal engine temperature. Partial or split-design fronts feature removable center sections or built-in flaps that allow you to adjust airflow based on temperature and load conditions. Many drivers prefer the split design for its versatility, especially if you operate in varying climates or pull heavy loads that require additional cooling.

Can I use a winter front and bug screen together, and how do they affect engine temperature?

Yes, many designs allow you to layer a bug screen behind your winter front for year-round protection. However, using both simultaneously requires careful temperature monitoring. Winter fronts can raise coolant temperatures by 10-20 degrees in cold weather, which is their intended purpose. Always monitor your temperature gauge when first installing, and consider a winter front with adjustable vents if you frequently encounter temperature variations. Remove or open vents if temperatures exceed 40 degrees F or when hauling heavy loads.
