Review on 🚰 Spill-Free Radiator Coolant Filling Funnel Kit, Thorstone No Spill Coolant Funnel with Adapters, Automotive Antifreeze Bleeder for Universal Vehicles - Spill Proof Radiator Funnel by Mike Shah

Works great for installing a new coolant in a 2007 Prius. This generation has a very complicated coolant path and it takes a long time and can take many cycles to get all the air out, but this funnel worked well for that. Without such a funnel, this process would not be possible because the expansion of trapped air in the system would allow up to a liter of refrigerant to flow into the funnel before the air is pushed out and all of the refrigerant flows back in. One note: if you use an offset, the funnel won't hold the full charge of coolant, so you'll need to support it to keep it from collapsing and squirting coolant (like it did on a 2004 Sienna minivan). ). )
