I purchased this kit to help with the coolant flush on my Honda. With the ridgeline sometimes it takes a bit of time to purge all of the air out of the system and you need to keep the radiator level full during the procedure. This unit makes it easy and when you鈥檙e done you just put the t handle stopper in the funnel outlet, remove the funnel from the vehicle and then let the excess coolant pour back in the container. There was also an adapter included that fit my wife鈥檚 car. Once you鈥檙e ready to put it away all the parts go in the funnel and there鈥檚 a top cover to ensure everything stays together for when you need it next. Great product.
