Review on Thorstone No Spill Coolant Funnel Kit: Spill-Free Radiator Filling & Antifreeze Bleeding for Universal Vehicles by Get Maldonado

Needed 2 45 degree elbows and an airtight cover for my system. The cap didn't fit properly and I used the correct adapters on my Pontiac. The hose is not twisted very tightly. Only when the tube is fully inserted into the knee is there a strong contact that can be held. Once the water and antifreeze wets it, it looks like silicone and the weight of the liquid funnel falls, and here is your expensive antifreeze. I tried tightening it a few more times but the pipes had to be taped or something to keep the system from twisting at the elbows and falling off. I got burned and was unhappy with the amount of antifreeze that ended up on my property where my water is good. Don't expect much from it when you need all your elbows and pipes to work together. Also, even with my correct fluid level, it didn't have enough capacity and the funnel overflowed and burned me trying to hold it together. Again, this is a pressurized system and hot water overflow may not be as severe in an open system. For me it was a complete failure.
