Lisle 24680 No Spill Coolant Funnel Kit

Works well! No more worries about leaving air bubbles in car cooling sytem when I flush and change coolant.......and no more spilled coolant. Attach the funnel to radiator spout, over fill the funnel (about half way) , start the engine and run until radiator blow comes on. Run for a while longer. As coo;ant begins to circulate thru the engine then watch the air bubbles bubble up through the coolant in the funnel. Run engine until no more bubbles bubble up through the excess coolant in the funnel. No more bubbles means no more air bubbles left in the engine. I have a 99 Honda Accord and because air bubbles remained in the cooling system the car would not start cold and even when the car started the coolant fan would not go on. After I removed the air using the no spill funnel the car starts perfectly and coolant fan runs at the appropriate time and temp. PS Spent two days chasing what I thought was a short or a faulty sensor before I found I had bubbles in the coolant that were was causing all the malfunctions. PSS I followed Honda procedures when draining and replacing old coolant but that procedure did not remove all the bubbles in the coolant system ...but No Spill Funnel removed all the bubbles! I like Spill free Funnel a lot!!
