Removal Procedure
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.
1. Drain the cooling system.
2. Remove the radiator outlet hose from the radiator.
