Q&A

-
-
-
Q1: What are the primary signs that my Komatsu PC450-8 radiator needs to be replaced?
-
A: Common indicators include persistent engine temperature alerts on the cab monitor under normal load, visible external coolant leaks at the tank-to-core seams, or a core that has suffered extensive physical damage (crushed fins) from external impacts or aggressive pressure washing.
Q2: Should I flush the cooling system when installing the new 208-03-77651 radiator?
-
A: Yes. It is highly recommended to flush the entire cooling system to remove accumulated scale, rust, or old degraded fluid before installing a new radiator. Refilling the system with clean, OEM-specified coolant prevents premature internal corrosion and maintains optimal heat transfer.
Q3: Does this radiator include the rubber isolation mounts?
-
A: This part number typically covers the core and tank assembly. It is standard practice to transfer the structural mounting brackets and shrouds from the existing unit, though inspecting and replacing worn rubber isolation mounts during installation is highly recommended to minimize vibration transfer.
