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 protect the environment. Five adapters fit most domestic and import cars, light trucks and Ford vehicles. 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. 21920 Lid for Funnel (will fit all older Funnels) 22210 Funnel (NOW CLEAR) 22280 45 Degree Elbow 22300 Fluid Stopper 22330 Large Cap A 22340 Medium Cap B 22370 Large Adapter A with Gasket 22390 Medium Adapter B with Gasket 22410 Small Cap C 22450 Small Adapter C with Gasket 24640 Threaded Cap D 24650 Adapter D with Gasket for GM 24670 5" Straight Extension 25390 Adapter E with Gasket for Ford Gasket Only: ---------------------------- A 22310 B 22320 C 22400 D 24660 E 25380 *Made of polyurethane
