How does construction affect reliability and cooling?

This radiator uses a TIG-welded aluminum core plus PA66 GF30 inlet/outlet tanks to combine lightweight heat transfer with robust connections that resist cracking. High-density multi-louvered fins increase surface area for better heat dissipation, and a treated coating helps protect against corrosion and environmental wear.

• TIG-welded core for secure, long-lasting seam integrity.
• Multi-louvered fins for improved cooling efficiency under load.
• Glass-filled nylon tanks to reduce risk of stress fractures in cold climates.
• Protective finish to guard against corrosion and road contaminants.
