Automotive Mechanics Spill Free Proof Fluid Coolant Funnel Spout GM Radiator Cap

Improved. Includes threaded cap and adapter for newer GM "threaded style" radiator openings. The Spill-Free Funnel eliminates trapped air pockets which usually cause erratic cooling system and heater performance. It controls the proper amount of coolant entering system and enables unattended filling of the cooling system. The funnel eliminates squeaky belts caused by coolant overflow and protects the environment. Four adapters fit most domestic and import cars and light trucks. Angled neck allows use on radiator caps that are placed at an angle. GM Threaded Cap is found on: 04-07 Grand Prix; 06-07 Buick; 04-07 S10 Blazer, Canyon, Colorado, SSR, Trailblazer and Olds Bravada; 07 GMC Acadia; 06-07 Hummer, Torrent, Equinox and Tahoe

The Spill Free Funnel has been improved by adding an extra 45 degree elbow, a 5” extension, and a new E adapter. The E adapter is used on the surge tanks on many Ford applications. 45 degree elbow allows use on radiator caps that are placed at an angle. Extension allows access to caps located under shrouds or in fender wells.
