Frequently Asked Questions About Freightliner FL70-FL80 Windshield Accessories

What years and models are these windshield accessories compatible with?

Our windshield accessories are designed to fit Freightliner FL70 and FL80 models from 1992 through 2010. However, there were minor variations in windshield dimensions between pre-2000 and post-2000 models. We recommend verifying your specific year and VIN with our customer service team to ensure proper fitment, especially for accessories like sun visors and windshield trim pieces that require precise measurements.

Are the replacement windshields DOT approved and what thickness glass is used?

Yes, all replacement windshields we carry meet or exceed DOT safety standards and feature laminated safety glass construction. The standard thickness is 6mm for both tinted and clear options. Our windshields include the proper AS1 marking for legal compliance and come with a pre-installed shade band at the top. Each windshield is manufactured using OEM specifications to ensure proper fit and optical clarity.

How difficult is it to install windshield wipers and arms, and what tools are needed?

Installing wiper arms and blades is typically a 30-minute job that most operators can handle themselves. You'll need a 15mm socket or wrench to remove the wiper arm nuts, and possibly a wiper arm puller if the arms are seized. The most common challenge is corrosion on the wiper post splines. We recommend applying penetrating oil before removal and anti-seize compound during installation. Always mark the wiper arm position on the windshield with tape before removal to ensure correct placement.

What's the difference between OEM and aftermarket sun visors, and will they mount to existing brackets?

Aftermarket sun visors are typically made from ABS plastic with vinyl covering, while OEM visors often feature fiberglass construction. Both options will mount to your existing bracket system using the standard 3-bolt pattern. The main differences are in longevity and price point - OEM visors generally last 5-7 years versus 3-4 years for aftermarket options. All visors we stock include the mounting hardware and measure the standard 7 inches in drop length.

Do windshield gaskets come with installation adhesive, and how do I know when to replace them?

Windshield gaskets do not come with adhesive pre-applied, as proper installation requires specific urethane sealant that must be applied fresh. You should replace your gasket if you notice water leaks, wind noise above 45 mph, visible gaps or tears, or if the rubber has become hard and brittle. A good gasket should feel pliable and compress evenly when pressed. We recommend using butyl tape for the initial seal and urethane adhesive for the permanent bond, both of which we carry separately.
