WARNING: This page is about a different car, the 2003 GMC Sierra, 2003 GMC Cab & Chassis Sierra, 2003 Chevrolet Silverado, and 2003 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT: Most truck models use a spring-type hose clamp at the hose connections. When using this type of clamp, install the radiator hoses on dry, non-painted surfaces in order to ensure proper sealing. Reusing the spring-type clamps on aftermarket hoses is not recommended.

  2. Reposition the inlet hose clamp at the radiator.
  3. Remove the inlet hose from the radiator.
