What years and models are these radiators compatible with?
Our International 4700-4900 radiators are designed to fit models from 1989 through 2001. The 4700 series typically uses a 2-row core design, while the 4900 series often requires a 3 or 4-row core depending on your engine configuration. Always verify your VIN and engine model (DT466, DT530, or T444E) before ordering, as cooling requirements vary between diesel and gas engines.
Are these aluminum or copper/brass radiators, and which is better for my truck?
We carry both aluminum and copper/brass options. Aluminum radiators are lighter (about 40% less weight) and provide excellent cooling efficiency with modern tube designs. Copper/brass radiators are heavier but easier to repair at local shops and tend to last longer in corrosive environments. For most highway applications, aluminum works great. If you operate in coastal areas or use road salt frequently, copper/brass might be the better long-term investment.
Will I need special tools or modifications to install these radiators?
Installation is typically straightforward and requires basic hand tools - no cutting or drilling needed for direct-fit models. You'll need to drain and refill coolant (approximately 6-8 gallons), transfer your existing mounting brackets if not included, and reconnect upper/lower hoses and transmission cooler lines if equipped. Most installations take 2-3 hours. Watch for proper fan shroud alignment to prevent blade contact.
What's the difference between 2-row, 3-row, and 4-row cores?
Row count refers to the number of cooling tube layers. 2-row cores work fine for standard DT466 engines under normal loads. 3-row cores provide about 30% more cooling capacity for heavy hauling or hot climate operation. 4-row cores are recommended for severe-duty applications, frequent mountain driving, or if you've increased engine horsepower. More rows mean better cooling but also higher cost and slightly restricted airflow.
Do these radiators come with warranty coverage, and what about shipping damage?
Most radiators include a 1-2 year manufacturer warranty covering defects in materials and workmanship. Always inspect your radiator immediately upon delivery before signing. Check for bent fins, damaged tanks, or loose fittings. We package radiators in heavy-duty boxes with protective padding, but shipping damage can occur. Report any damage within 48 hours with photos for fastest resolution. Keep all packaging until you've confirmed fit and function.
