Frequently Asked Questions About International S1700-S1900 Radiators
Will this radiator fit my specific International S1700 or S1900 model year?
Radiator fitment on the International S1700 and S1900 series can vary depending on engine option, cab configuration, and production year. Always check core dimensions (height, width, and thickness), inlet and outlet placement, and mounting tab locations against your truck's original radiator before purchasing. If you're unsure, have your VIN and engine specs ready so our team can confirm compatibility.
What material is the radiator core and end tanks made of?
Most replacement radiators for these models feature aluminum cores for efficient heat transfer paired with either plastic or metal end tanks, depending on the manufacturer and whether the unit is OEM-style or aftermarket. Metal tanks tend to hold up better under long-term heat cycling and rough duty use, while plastic tanks are lighter and more budget-friendly.
Is this a direct OEM replacement, or will I need to modify anything during installation?
Many of the radiators in this category are built to OEM specifications and are designed as direct bolt-in replacements, but some aftermarket units may require minor adjustments to hoses, brackets, or shrouding. Review the product description and included hardware list carefully, and compare mounting points to your existing radiator before installation.
How do I know if I need a new radiator versus a repair?
Common signs that point to full replacement rather than a repair include visible core damage, repeated leaks after previous fixes, corrosion around the tanks or seams, or consistent overheating even after flushing the cooling system. If your radiator has minor tank cracks or a single damaged fin area, a shop may be able to repair it, but core damage or widespread corrosion usually calls for replacement.
Does this radiator come with a warranty, and what does it typically cover?
Warranty coverage varies by brand and whether the radiator is new, OEM, or aftermarket. Most warranties cover defects in material or workmanship for a specified period but do not cover damage from improper installation, coolant contamination, or collision damage. Check the specific product listing for warranty length and terms before you buy.
