GM 10157994 Tank Assembly, Radiator Surge

The first step to remove the radiator includes disconnecting the negative terminal of the battery cable and draining the cooling system. The first step entails removing the air intake duct together with the upper fan shroud. Vehicle owners must carefully disconnect automatic transmission and engine oil cooler lines from the radiator with plugging or tubing to stop leaks and entry of contaminants at the ready. Install a drip pan underneath. Disconnect radiator upper and lower hoses before taking out the lower fan shroud through screwdriver operation of plastic tabs. End the radiator removal by pulling it directly upward. Before you install the radiator replace all defective hose clamps and radiator hoses then check for leaks and test when cooling problems existed. The installation proceeds in the reverse direction of removal while new spring clips secure the oil cooler connections and required the push of oil cooler lines until they secure into position. Before using the system complete the filling process with the correct antifreeze mixture and check automatic transmission fluid levels when needed. The coolant reservoir must be taken out through an access that differs per model so you must detach both the overflow hose and the mounting nuts to get the tank out. A clean reservoir without debris should be present when fitting reservoir components through backward installation steps.
