GM 22727322 Radiator Assembly (Service)

Unplug the ground cable at the car's battery, take off the engine cover with air filter, empty the engine coolant, and take off the hood release lever. Open the hood and disconnect the two nut covers holding the shroud. After pulling out six bolts and removing the fan shroud, gently remove radiator cover. Then lift the entire cooling fan structure off the radiator and put it somewhere nearby. For automatic transmission vehicles, disconnect both of its oil cooler lines from the radiator, and then take off both radiator hoses. Press the tabs on the unit to separate it from the radiator, then put it aside. Lift out the radiator very slowly while watching for leaks and keeping the paint from scratching. Keep the rubber radiator insulators where they should be for when you put everything back together. First, blow away dirt with compressed air and a gentle brush, check for problems, and bring your radiator to a repair shop to fix it. Before installing, check the rubber insulators for cracks and make sure dirt and gravel aren't stuck to them. Put the radiator back just the opposite of how it was taken out. Following the installation, mix the right antifreeze-water blend, reconnect the battery, turn on the engine, look for fluid leaks, let it run until it gets warm (as shown by the upper hose heating up). Check coolant again, top up when needed, and fill the automatic transaxle fluid if needed.
