Frequently Asked Questions About Freightliner Century 112/120 Radiators

Will these radiators fit my specific Freightliner Century model year?

Our radiators are designed to fit Freightliner Century Class 112 and 120 models from 1996 to 2010. However, there are variations based on engine type (Detroit, Caterpillar, or Cummins) and whether you have a single or dual radiator setup. Before ordering, check your VIN and existing radiator part number, or contact us with your truck's year, engine model, and current radiator configuration for exact fitment verification.

What's the difference between aluminum and plastic tank radiators, and which should I choose?

Aluminum radiators offer superior heat dissipation and durability, typically lasting 8-10 years with proper maintenance. They handle temperature fluctuations better and are repairable if damaged. Plastic tank radiators are more affordable upfront but generally need replacement every 4-6 years and can crack under extreme temperature changes. For heavy-duty applications or frequent long hauls, we recommend aluminum for its longevity and performance.

Can I install the radiator myself, or do I need a professional?

Installation typically takes 3-4 hours for experienced DIY mechanics. You'll need basic tools including wrenches, pliers, and a coolant drain pan. The main challenges include properly aligning mounting brackets, ensuring all hose connections are secure, and bleeding the cooling system correctly. If you're not comfortable working with cooling systems or lack the proper tools, professional installation is recommended to avoid costly engine damage from improper installation.

How do I know if I need a standard or heavy-duty radiator?

Heavy-duty radiators feature additional cooling rows (typically 4-row vs 2-row) and are essential for trucks that regularly haul maximum loads, operate in mountainous terrain, or run in extreme temperatures. If your truck frequently runs hot, pulls heavy loads over 70,000 lbs, or operates in temperatures above 90?F regularly, opt for heavy-duty. Standard radiators work well for typical highway driving and moderate loads under 60,000 lbs.

What warranty coverage comes with these radiators, and what voids it?

Most radiators come with a 1-2 year manufacturer warranty covering defects in materials and workmanship. The warranty does not cover damage from improper installation, contaminated coolant, physical impact, or overheating due to other engine problems. To maintain warranty coverage, use only recommended coolant types, perform regular cooling system maintenance, and keep documentation of service records. Always register your warranty within 30 days of purchase.
