Greetings Scotty! I've been watching your videos for a while now and I appreciate the content that you provide. On to the question---> I've got a 99 ford ranger 3.0 v6 and lately it has been having some weird issues with the radiator/cooling system. I've noticed that whenever I put coolant into the overflow tank, it gets sent to the radiator as any normal car should, however, the coolant from the overflow tank doesn't return back from the radiator into the tank as it should after the motor cools down, etc. I don't see any leaks near or around the radiator or leaks around the thermostat and water pump. If it's possible, could you create a short video explaining this weird phenomenon? Thanks a lot.
