OEMTOOLS 87045 No Spill Coolant Filling Funnel Kit with Coolant Tester provides everything you need for diagnostic temperature checks and coolants refills. This cooling system refill kit's no-spill funnel burps fluids and oils without mess. The funnel with long tube can perform engine and radiator flushes, coolant and power-steering fluid refills. Simply select the correct adapter, attach the funnel and fill. 45 degree angled and 5” extension adapters ensure that you can access hard to to access spots and the fluid stopper prevents drips and spills when removing the filler neck. The adapters' gaskets prevent radiator fluid leakage while filling or flushing systems.

Many of the adapters and pieces that come with the radiator flushing kit can be stored in the large funnel after use.
