What are the core specifications of the TYC 2855 Hummer Radiator?

The TYC 2855 Hummer Radiator features a vehicle-specific fit designed to match original equipment specifications, including OE-comparable mounting provisions and an OE-comparable harness.

This radiator, which serves as a heat exchanger to keep an engine cool by circulating fluid through metal fins, is an OE-equivalent part that has undergone rigorous and accelerated cycling tests to ensure reliability. Because it is a vehicle-specific fit, the mounting brackets align with the original Hummer layout, and the inlet/outlet hose diameters are designed to match stock hoses directly. We selected the TYC 2855 for our comparison because it provides a direct replacement for factory units without requiring a pigtail connector. While the unit includes the core, it does not include the cooling fan assembly; you must ensure your existing fan setup is functional before installation. For radiator buyers, verifying hose diameters and mounting points is critical because even a slight mismatch in bolt placement can prevent the unit from seating correctly against the frame.

What to Check Before Buying the TYC 2855 Radiator

Confirm these specific technical details to ensure the unit fits your specific vehicle configuration before ordering.

• Verify that your current cooling fan assembly is compatible, as this unit provides the core only.
• Confirm your vehicle’s required coolant type, as using the wrong fluid can cause chemical reactions with the radiator material.
• Check that there is sufficient clearance for the AC condenser to ensure the radiator sits flush against the mounting points.
• Ensure your existing hose diameters match the inlet and outlet ports to avoid the need for adapters.
• Consult the manufacturer’s compatibility page to confirm the specific year and trim of your Hummer are supported.

Comparing the TYC 2855 Radiator to Other Options

The TYC 2855 Radiator is positioned as a standard replacement for those seeking an OE-equivalent part that maintains factory dimensions. If you require a high-performance racing radiator with specialized cooling cores or heavy-duty heat dissipation for extreme towing, you may want to look at aftermarket performance options. However, for most owners who need to restore factory cooling capacity without modifying the engine bay, this model provides the necessary mounting and harness compatibility.
