Assume the system has automatic drain valves
							                                
                                        
                                    
							                        
                    
                            Nothing; it's the vehicle owner's responsibility
							                                
                                        
                                    
							                        
                    
                            Find out whether you need to drain the system manually
							                                
                                        
                                    
							                        
                    
                            Leave the engine running for a while before driving
