Frequently Asked Questions About International 9300/9370 Windshield Wiper Accessories

Will these wiper blades and arms fit my specific year International 9300 or 9370?

Most windshield wiper accessories in this category are designed to fit International 9300 and 9370 models from 1987 through 2007. However, there were minor changes in mounting hardware between early models (1987-1999) and later models (2000-2007). Always verify the specific part number against your VIN or existing wiper arm style. If you're unsure, measure your current wiper arm length and mounting bolt pattern before ordering.

What's the difference between standard and heavy-duty wiper motors, and which one do I need?

Standard wiper motors are sufficient for typical highway driving conditions and cost less. Heavy-duty motors feature stronger internal gears and higher torque output, making them ideal for trucks operating in severe weather, construction sites, or with oversized wiper blades. If you frequently drive in heavy snow, ice, or use 24-inch or longer blades, invest in the heavy-duty option. Most drivers report standard motors lasting 3-5 years, while heavy-duty versions often exceed 7 years.

Can I install these wiper components myself, or do I need special tools?

Most wiper blade and arm replacements can be completed with basic hand tools in 15-30 minutes. You'll typically need a 13mm or 15mm wrench for arm removal and possibly a small flathead screwdriver for electrical connections. Wiper motor replacement is more involved, requiring dashboard access and usually takes 1-2 hours. The main challenge is reaching the mounting bolts behind the dash. Having a second person helps significantly when aligning the linkage.

Why do my new wiper blades streak or chatter even though they're brand new?

This common issue usually isn't the blades' fault. First, clean your windshield thoroughly with glass cleaner and check for pitting or scratches. Worn wiper arms often lose proper spring tension, causing poor blade contact. If arms are over 5 years old, replace them along with the blades. Also verify you've purchased the correct blade length - 9300/9370 models typically use 22-inch blades, but some configurations require 24-inch. Using the wrong size causes uneven pressure and streaking.

Are aftermarket wiper motors as reliable as OEM parts?

Quality aftermarket motors from established manufacturers like Cardone, WAI, and Dorman typically match OEM performance at 40-60% less cost. These brands use the same specifications as original equipment and often improve on known weak points. Avoid extremely cheap no-name motors under $50, as they frequently fail within months. Look for motors with at least a 1-year warranty. Most professional drivers report no difference in performance between quality aftermarket and OEM motors when properly installed.
