• Q: How to replace the radiator on a 4.3L engine on 2005 Chevrolet Blazer?

  A: The first step to replace the Radiator of a 4.3l engine begins with draining the cooling system. The first task involves moving the Radiator clamp on the coolant recovery hose and disconnecting the hose through its reservoir. Radiator inlet hose clamp relocation and hose removal is accomplished using the hose clamp pliers (J 38185). After removing the Fan Shroud you will reposition the Radiator outlet hose clamp with hose clamp pliers (J 38185). Take out engine oil cooler lines together with transmission oil cooler lines from the Radiator as the last step to extract the Radiator. The first step for installation is to inspect the rubber mounts prior to inserting the new Radiator. Affix first the new transmission oil cooler lines and engine oil cooler line onto the Radiator before adding the Radiator outlet hose. You must use hose clamp pliers (J 38185) to adjust the Radiator outlet hose clamp position and afterward secure the Fan Shroud followed by the Radiator inlet hose before readjusting the Radiator inlet hose clamp through hose clamp pliers (J 38185). After connecting the coolant recovery reservoir hose you should reposition its clamp before beginning the cooling system filling process.
