Spill Free Funnel with GM Adapter

The Spill Free Funnel, No. SFF2A, from Matco includes threaded cap and adapter for newer GM threaded radiator openings. The funnel eliminates squeaky belts caused by coolant overflow and trapped air pockets which usually cause erratic cooling system and heater performance. Four adapters fit most domestic and import cars and light trucks. The angled neck allows use on radiator caps that are placed at an angle.
