What This Radiator Helps Address

• Engine overheating caused by reduced coolant flow or heat transfer
• Cooling system leaks from a worn or damaged radiator core or tank
• Temperature instability during stop-and-go driving or towing
• Fitment issues when replacing an OE radiator with the correct dimensions
• Cooling performance loss from age-related corrosion or internal restriction

Installation Notes and Tips

Verify the vehicle’s engine oil cooler configuration before ordering, since fitment varies by application. Confirm inlet and outlet hose sizes, mounting points, and core dimensions against the original radiator before installation. Flush the cooling system, inspect hoses and clamps, and refill with the correct coolant mixture after replacement. This radiator does not include a transmission oil cooler.

Quality Assurance

Denso states that its radiators are built to OE manufacturer standards and undergo durability and function testing before release. That quality process supports reliable cooling performance and proper fitment for the listed Ford Explorer, Ford Flex, and Lincoln MKT applications.
