Q&A Section
Q1: Will this radiator fit the newer D61EX-23 or -24 models?
A: No. The 134-03-71112 is specifically designed for the -15 series. Newer models utilize different emission-tier cooling packages with varied dimensions and hose locations.
Q2: Does it come with the side brackets and shroud?
A: This part number usually refers to the radiator assembly (core and tanks). Side supports and the fan shroud are typically transferred from your existing unit unless a complete "Cooling Package" is ordered.
Q3: Why is my D61EX-15 still running hot with a new radiator?
A: On the D61-15, cooling is assisted by a hydrostatic fan. If the radiator is clean and new, check the fan motor and the thermal sensors that control fan speed. A malfunctioning fan controller will cause overheating even with a perfect radiator.
