Frequently Asked Questions About Freightliner FLD SBA Radiators

Will these radiators fit my specific Freightliner FLD model year?

Our Freightliner FLD SBA radiators are designed to fit FLD 112, FLD 120, and FLD 132 models from 1990 through 2007. However, compatibility can vary based on your engine configuration (Detroit, Caterpillar, or Cummins) and whether you have a standard or set-back axle. We recommend checking your current radiator's core dimensions and inlet/outlet positions before ordering. If you're unsure, our team can help verify fitment with your VIN number.

What's the difference between aluminum and plastic tank radiators for my FLD?

Aluminum tank radiators typically offer better heat dissipation and longer lifespan (8-12 years) compared to plastic tank models (5-7 years). While plastic tank radiators are more budget-friendly upfront, they're prone to cracking at the tank-to-core crimps, especially in extreme temperatures. Aluminum radiators handle thermal cycling better and can be repaired if damaged, whereas plastic tanks usually require complete replacement. For heavy-duty applications or severe service, we strongly recommend aluminum construction.

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

Installation typically takes 2-4 hours for experienced mechanics. You'll need basic hand tools, a coolant drain pan, and possibly a hoist for heavier all-aluminum units. The main challenges include properly aligning the mounting brackets, ensuring all hose connections are secure, and bleeding the cooling system completely. Some models may require transferring your existing oil cooler lines or transmission cooler fittings. Always replace the radiator cap and thermostat during installation for optimal performance.

How do I know if I need a 2-row or 4-row core radiator?

Core row count depends on your engine size and application. Standard highway trucks with Detroit 60 Series or similar engines typically use 2-row cores effectively. However, if you're running heavy loads, operating in mountainous terrain, or have a high-horsepower Caterpillar or Cummins engine, a 4-row core provides additional cooling capacity. Vocational trucks, dump trucks, or those with auxiliary equipment should opt for maximum cooling capacity. Check your current radiator's specifications or consult your engine's cooling requirements.

What warranty coverage should I expect, and what voids it?

Most quality FLD SBA radiators come with 1-2 year warranties covering manufacturing defects and premature failure. Warranty typically excludes damage from improper installation, contaminated coolant, physical impact, or overheating due to other engine problems. To maintain warranty coverage, use proper coolant mixture (typically 50/50), flush the system before installation, and ensure your radiator cap maintains correct pressure. Keep your purchase receipt and document any maintenance performed.
