Frequently Asked Questions About International LoneStar Radiators

Will these radiators fit my specific International LoneStar model year?

Our International LoneStar radiators are designed to fit models from 2008 to present. However, there are variations between early models (2008-2012) and later models (2013+) due to mounting bracket changes and inlet/outlet positions. Always verify your VIN and engine type (ISX, MaxxForce, etc.) when ordering. If you're unsure, our team can help confirm compatibility with your specific truck configuration.

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

Aluminum radiators offer superior heat dissipation and durability, typically lasting 8-10 years with proper maintenance. They handle extreme temperature fluctuations better and are less prone to cracking. Plastic-tank radiators are more budget-friendly upfront but may need replacement every 5-7 years. For heavy-duty applications or extreme climates, we recommend aluminum construction despite the higher initial cost.

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

Installation typically takes 3-4 hours for experienced mechanics. You'll need basic tools including wrenches, coolant drain pan, and new coolant. The main challenges include properly aligning mounting brackets, ensuring all hose connections are secure, and bleeding the cooling system correctly. Many customers successfully complete DIY installations, but improper installation can cause overheating or leaks. Professional installation usually costs $200-400 but ensures proper fitment and system bleeding.

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

Heavy-duty radiators feature additional cooling rows (typically 4-row vs 2-row) and are essential for trucks regularly hauling maximum loads, operating in mountainous terrain, or running in extreme heat. If your truck frequently runs hot, pulls heavy loads over 70,000 lbs, or you've added performance modifications, upgrade to a heavy-duty option. Standard radiators work well for typical highway driving and moderate loads.

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

Most quality International LoneStar radiators come with 1-2 year warranties covering manufacturing defects. Warranties typically exclude damage from improper installation, contaminated coolant, physical impact, or overheating due to other engine problems. To maintain warranty coverage, use proper coolant mixture (usually 50/50), perform regular flushes, and keep documentation of maintenance. Some manufacturers offer extended warranties for an additional cost.
