First, disconnect the negative battery cable and allow the radiator to drain. Continue by disconnecting upper and lower hoses of the radiator as well as the automatic transmission cooling lines if they exist. Unbolt the shroud of the radiator and hang it over to a fan, which is fastened with screws into the radiator with clips or staples on its bottom side. Remove the top metal panel on top of the radiator. Lift the radiator out straight from engine compartment making sure that you don't scratch off paint on front nose piece. If any coolant drips onto body paint, wash it off immediately with clear water as antifreeze solution can damage finish. Detach, examine for leaks or damages once removed from vehicle's front grille-should repairs become necessary have an engineer do replacement at their workshop since special welding techniques are necessary in such instances. While cleaning bugs, dirt may be done using compressed air and soft brush but don't bend fins that cool engines. Check for rubber mounting pads where radiators rest, replacing if required. Lift up radiator ensuring it is put squarely on its mounting pads. Reverse removal steps include upper panel installation, shroud attachment, and hose connections. After connecting a negative battery cable fill up a radiator completely. Start an engine with a view of checking any leakages that might have arisen during disconnection process earlier made until then move into adding coolants by allowing an engine to run until normal working temperature is achieved while ensuring that coolant reaches bottom neck filler level position. Finally put the cap back on in order to align arrows with overflow tube.
