Frequently Asked Questions About International Engine Parts & Cooling
Will these cooling parts fit my specific International truck model and year?
Our International engine cooling parts are designed for specific model years and engine types. Most radiators, water pumps, and thermostats fit International trucks from 1999-2024, including ProStar, LoneStar, 9900i, and 4000/8000 series. Always check the product description for your exact engine model (DT466, MaxxForce, N13, ISX) and year range. If you're unsure, contact us with your VIN number and we'll verify compatibility before you order.
How difficult is it to install a radiator or water pump on my International truck?
Radiator replacement typically takes 2-4 hours for experienced mechanics and requires basic tools plus coolant drainage equipment. Water pump installation is more complex, usually requiring 4-6 hours and specialized tools like a harmonic balancer puller. Most customers report that having a service manual is essential. Common challenges include accessing tight mounting bolts and properly bleeding the cooling system. We recommend professional installation if you're not comfortable working with cooling systems.
What's the difference between OEM and aftermarket cooling parts for International trucks?
OEM parts are manufactured to International's exact specifications and typically carry a 1-2 year warranty. Aftermarket options from brands like Dorman, Gates, and Spectra Premium often cost 30-50% less while meeting or exceeding OEM standards. Key differences include core thickness on radiators (aftermarket may offer upgraded 2-row or 3-row options), material quality on water pump impellers (cast iron vs. plastic), and thermostat opening temperatures. Most customers find quality aftermarket parts perform equally well for standard applications.
How do I know if I need aluminum or plastic/aluminum radiators for my International?
Most International trucks from 2007-newer use plastic/aluminum radiators as standard, while pre-2007 models often have all-aluminum units. Plastic/aluminum radiators are lighter and less expensive but may crack at the tanks after 5-7 years. All-aluminum radiators cost more upfront but are repairable and typically last 10-15 years. For severe-duty applications or hot climates, we recommend upgrading to all-aluminum with increased core capacity for better heat dissipation.
What other parts should I replace when changing my radiator or water pump?
When replacing a radiator, always install new upper and lower radiator hoses, hose clamps, and a thermostat. For water pump replacement, change the drive belt, coolant, and inspect the fan clutch. Many customers overlook the radiator cap - a faulty cap can cause overheating even with new components. Budget an extra $150-300 for these supporting parts. Also check your coolant overflow tank for cracks and replace if necessary to prevent air pockets in the system.
