Review on 💧 Efficient No-Spill Coolant Filling with OEMTOOLS 87009: Simplify the Process! by Johnny Bloomer

Update: 7/28/2021 - Metal caps are poorly made of thinner metal. If the pressure is too high, the metal will deform. The rubber seal is also bad. I had leaks. So I used metal washers as spacers. I am very sorry that I threw away the metal caps from my old kit. I attach it to the radiator and start my Honda Civic with the funnel half full. I set the A/C temp to hot and crank the engine until the coolant is hot enough to open my thermostat. I'm going to run the car a little more to see if the fans come on to check the operation of the fans and fan switch. I'm going back to random RPMs to get air out of the cooling system. When I'm satisfied, I turn off the car and turn on the air conditioning to let the radiator fans cool and condense the coolant. When that's done, I squeeze the upper radar tube a little, then put the plug in the funnel and remove the funnel. I then empty my reservoir with old coolant and fill it about 1-2 inches above the top line with coolant in the funnel. The rest is drained into the coolant reservoir. I go back to the car, gently squeeze the top radiator hose and watch the coolant rise to the top inner rim where the radiator cap gasket is, then reinstall the cap. I don't really like the funnel lid. The inner edge of the rubber boot is deformed and even stretching will not fix this as it was also done wrong. You can save a lot of material and weight by making only one plastic cap. I ended up throwing the lid away because it was just unusable.
