I do a lot small maintenance on my cars at home and this funnel kit is a great addition to my tool collection. It really makes the coolant flush/replacement a joy. It helps to "burp" the coolant at the end as well. There is plenty of adapters for any car out there so you all you need is this one kit. The only time you get just a little bit of spill is at the end when your funnel still contains some coolant and you need to remove the funnel from the radiator. The you stick the stopping rod into the bottom of the funnel, and that last bit of coolant in the throat of the funnel will spill over, but all you need is a small rag around the cap area and it will absorb it. Nothing to worry about at all. I do recommend this product to anyone working on their cars, it;s the money well spent.
