2000 Cadillac Catera Radiator Parts and Q&A

• Q: How to service and repair the radiator on 2000 Cadillac Catera?

  A: The service procedure requires Battery Cable negation before Radiator work begins. The first service step includes releasing self-locking tabs on upper Radiator covers before unscrewing their upper Radiator cover screws. First drain engine coolant from the system before removing the intake air resonator. The electrical connectors at the primary cooling fan and cooling fan control switches require detaching. First disconnect the surge tank hose from the Radiator and disconnect the Transmission Oil Cooler hoses from the oil cooler pipes and proceed to remove Transmission Oil Cooler pipe retainer bracket bolts then securely position the pipes away from the Radiator. First disconnect the coolant hose from the secondary auxiliary coolant pump and then remove the secondary air cut-off valve bracket bolts from the fan housing as well as Transmission Oil Cooler to Radiator bracket bolts. After separation of the front condenser bracket bolts and Radiator inlet/outlet hoses from the Radiator it enables access for the Transmission Oil Cooler removal. Start by disconnecting the secondary auxiliary coolant pump connector then remove the upper mount retainers of the Radiator. Lift and gently shake the component before removing the lower retainers from the Radiator support. The primary fan bolts with the primary fan should be taken off the Radiator while also removing cooling fan control switches if needed. Start your installation process by putting back the cooling fan control switches which were taken off. Mount the primary fan to the Radiator by setting the tab then tighten its bolts to 4 nm (35 inch lbs.). Place the Radiator combination with the primary fan onto the support while confirming that its tabs lock into position at the retaining points and resting correctly in the brackets. The installation requires connecting secondary auxiliary coolant pump connector then attaching the Radiator inlet/outlet hoses with condenser-to-Radiator bracket bolts until they achieve full seating. Fasten the secondary air cut-off valve bracket onto the fan housing by using torque of 4 nm (35 inch lbs.). The coolant hose attaches to the secondary auxiliary coolant pump before installing Transmission Oil Cooler components with their bracket fasteners to a full stop while connecting Transmission Oil Cooler hoses to the oil cooler pipes along with retaining bracket installation to seat position. Finally install the surge tank hose to the Radiator as well as reconnect both primary cooling fan electrical connectors and cooling fan control switches. Follow installation of the intake air resonator with cooling system filling and conclude by positioning upper Radiator covers followed by screw and self-locking tab insertion before reconnecting the negative Battery Cable.
