163-4058
Radiator Model 163-4058 is specifically designed for the CAT D9R Dozer. Hot coolant from the engine passes through these tubes; air flowing through the attached fins carries away the coolant's heat. This process regulates engine temperature directly, preventing overheating.
Features
Facilitates heat transfer from coolant to surrounding air.
Main radiator component for heat transfer.
Fins on tubes increase surface area for better heat dissipation.

Maintance and Service
How We Produce
Our fin-and-tube assemblies are crafted with precision to expand heat transfer surface area, while vacuum brazing ensures seamless, leak-proof component bonding. Critical joints get an extra layer of reliability too, reinforced by TIG or MIG welding to avoid weak points.
We never compromise on quality: every unit goes through strict high-pressure testing and airtightness checks to ensure zero leakage. Before packaging, every component is assembled, inspected, and tested to our rigorous standards—so you can count on consistent, reliable performance from the final product.
