Radiator for International Harvester 766, 886, 966, 986, 1066, 1086, 1466, 1486, 1566, 1586 & Hydro

Description

When your International’s temperature gauge starts creeping up during long harvest days or heavy tillage work, you know that 40-year-old radiator has probably given all it’s got. These IH tractors were built to work hard for decades, but even the toughest cooling system eventually needs attention. This TISCO replacement radiator gets your cooling back where it should be, so you can focus on the work instead of watching that temperature gauge.

What You’re Getting

• Heavy-duty 6-row core with 8 FPI design that moves more heat than worn original radiators
• Exact dimensions match your original – 24 inch height, 22-1/2 inch width, and 3-7/8 inch depth
• Quality construction built to handle the vibration and temperature swings these tractors dish out
• All the right connections and mounting points for a direct swap – no modifications needed

Built for Real Farm Work

This radiator fits the workhorse IH tractors that built American agriculture – from the 766 through the big 1586 row-crop machines and the Hydro 100 and 186 models. Whether your 1066 is pulling a chisel plow through tough ground, your 986 is running a grain cart during harvest, or your Hydro 186 is handling loader work around the farmstead, these tractors work hard and need proper cooling to keep running strong.

Made to Last

TISCO builds this radiator to handle what these classic IH tractors throw at it. The multi-row core design provides excellent heat transfer while standing up to the debris, vibration, and temperature cycles that come with serious farm work. It’s engineered to match the cooling capacity your engine was designed for.

Installation Notes

Before installing, flush your cooling system thoroughly to remove any scale or debris that might have contributed to your old radiator’s problems. This is also the perfect time to replace those radiator hoses, check your water pump operation, and make sure your thermostat is opening properly – these systems work together, and old hoses often fail right after you disturb them.
