How to Replace the Radiator Hose for a 4.3L Engine on 2006 GMC Sierra 1500?

Changing the radiator inlet hose of a 4.3l engine starts with draining the cooling system fluid. You must loosen the hose clamp to split the mass airflow (MAF)/intake air temperature (IAT) sensor assembly from the air inlet tube before you disconnect the pcv hose from the air cleaner outlet duct. First loosen the hingeclip retaining nut to lift the assembly upward so the clip disengages from the Throttle Body. Remove both the radiator and Thermostat Housing from the radiator inlet hose by first relocating the hose clamp. During installation you should connect the new radiator inlet hose while properly positioning the clamps onto the radiator and Thermostat Housing. Install the hose on the support by aligning the Throttle Body hinge clip to its lip before you pivot the air inlet tube and resonator downwards to hold them in place by tightening the resonator retaining wing nut. The pcv hose installation sequence requires connecting it to the air cleaner outlet duct followed by maf/iat sensor assembly and air inlet duct installation and a final clamp tightening to 4 nm (35 inch lbs.). Finally, fill the cooling system.
