The Multiquip EE51146 Upper Water Line KTA50 Rocor Rad is a genuine OEM replacement designed for KTA50 series equipment. Sourced directly from Multiquip, this part meets the original engineering specifications for the KTA50 cooling system. If your cooling line is cracked, leaking, or deteriorated, the part is the correct OEM solution to restore proper coolant flow. Confirmed fitment for KTA50 models ensures you receive the right part the first time.
Key Features
- Genuine OEM Cooling Line Material — Manufactured to the same hose compound and wall-thickness spec as the original, maintaining pressure integrity throughout the cooling circuit.
- Direct Upper-Circuit Fit — Configured specifically for the upper coolant routing on the KTA50 Rocor radiator, connecting to OEM ports without adaptation or trimming.
- KTA50 Series Compatibility — Verified fitment for KTA50 equipment, eliminating guesswork when sourcing cooling system components.
- Restores Full Coolant Flow — A failed or leaking upper water line causes coolant loss and rapid overheating; replacing it with EE51146 returns the system to correct operating temperature range.
- Corrosion and Heat Resistant Construction — Built to withstand the thermal cycling and coolant chemistry demands of continuous heavy-equipment operation.
The upper water line carries hot coolant from the engine out to the radiator for heat dissipation, forming the high-pressure side of the cooling loop. When this line cracks, collapses, or develops a leak, coolant escapes and the engine loses its ability to shed heat — leading to overheating, potential head gasket damage, and unplanned shutdowns. Replacing a worn upper water line promptly keeps the entire cooling circuit sealed and operating within its designed temperature range.
