To remove the radiator on Cobalt/GS and ION models, start by disconnecting the cable from the negative battery terminal and raising the vehicle on jackstands. If applicable, remove the air cleaner outlet resonator and drain the cooling system, saving the coolant if it's in good condition. Remove the cooling fan(s) and shroud assembly, and on automatic transaxle models, remove the left fender well liner and disconnect the transaxle oil cooler lines from the radiator. Disconnect the upper and lower radiator hoses, and on 2.0L supercharged models, disconnect the coolant hoses at the bottom of the intercooler. Remove the bolts in each lower radiator mounting bracket and the condenser mounting bolts, and pull the condenser down slightly to disengage it from the radiator brackets. On 2.0L models, remove the bolts securing the intercooler to the radiator and pull the intercooler downward to disengage the clips at the radiator. Carefully lower the radiator until its pins are free at the top, then remove the radiator. For HHR models, disconnect the cable from the negative battery terminal and remove the air filter housing/engine cover assembly. Drain the cooling system and remove the hood latch, radiator support brackets, and radiator cover. Lift the cooling fan and shroud assembly off of the radiator and set it aside. On automatic transaxle models, disconnect the transaxle oil cooler lines from the radiator, and disconnect the upper and lower radiator hoses. Push the retaining tabs in to release the condenser from the radiator and place the condenser aside. Carefully lift the radiator up and out, making sure the rubber radiator insulators remain in place. Clean the radiator and inspect it for leaks and damage. To install the radiator, inspect the rubber insulators and ensure they're clean and in good condition. Then, follow the reverse of the removal procedure, filling the cooling system with the correct mixture of antifreeze and water, reconnecting the battery, checking for leaks, and adding fluid if necessary for automatic transaxle-equipped vehicles.
