OE-Style Cooling Construction
This radiator reflects Denso’s OE supplier background, with configurations, tank design, fin pitch, core dimensions, and materials selected to meet original manufacturer standards. The result is a radiator intended to maintain proper engine temperature control and stable cooling-system operation under everyday driving and demanding conditions.

What This Radiator Helps Address
- Engine overheating caused by a restricted or leaking radiator
- Coolant loss from cracked tanks or damaged core passages
- Transmission heat management when the factory cooler is part of the system
- Reduced cooling efficiency from age, corrosion, or internal blockage
- Temperature instability during stop-and-go driving or extended use
Installation Notes
Verify inlet and outlet hose sizes, mounting points, and transmission cooler line routing before installation. Flush the cooling system, inspect hoses and clamps, and replace degraded coolant as part of the repair. Confirm fitment against the vehicle’s year and model before final assembly, especially when servicing a 2000-2005 Toyota Echo or 2004-2006 Scion xB cooling system.
Quality Assurance
Denso subjects its radiators to durability and function testing to support consistent performance and fitment. Part number 221-3110 is built to OE-level dimensional standards for the listed Toyota Echo and Scion xA/xB applications.
