What It Helps Address

• Coolant leaks from a damaged radiator core or tank
• Overheating caused by restricted or inefficient heat transfer
• Cooling-system service on high-mileage Chevrolet Express and GMC Savana vans
• Replacement of a radiator with the wrong sensor-port or hose configuration
• Restoring proper engine temperature control after radiator failure

Installation Notes and Tips

Verify the year, model, and radiator configuration before ordering, especially for 2004 applications and vehicles noted without a sensor port or sensor hole. Confirm hose connection style and sensor-port requirements against the existing radiator before installation. Flush the cooling system, inspect hoses and clamps, and refill with the correct coolant specification after the radiator is installed.
