Q&A Section
Q1: Can I use this radiator for a WA470-6 or -7?
A: No. The WA470-8 series has a completely redesigned cooling stack to accommodate the DPF/SCR systems. Mounting points and hose diameters will not align with previous generations.
Q2: What is the benefit of the 421-03-61112 over the 421-03-61111?
A: The 421-03-61112 is the updated part number. It typically features improved internal bracing or upgraded seals to address thermal expansion more effectively than the original 61111 version.
Q3: Does this include the side frames and mounting brackets?
A: This part number usually refers to the radiator assembly (core and tanks). While it includes the main structure, you should verify if your specific supplier includes the outer protective guards or if those should be transferred from your old unit.
