DOUG JENKINS: Hi. I'm Doug. I work with 20 great guys in St. Louis at Doug Jenkins Custom Hot Rods, and we're going to do some work for you today on Expert Village. Dan is taking off the radiator overflow tube. The way modern-cooling systems like this are adjusted, coolant, when it expands, gets flushed into that white bottle on the other side. When it contracts when the engine is cool, it sucks it back out. In the old days, you used to just have a tube there that's spat on the ground, and you had a big air cavity in your radiator, and then the air would compress and expand every time the coolant got hot or cold, and you didn't have the cooling capacity you do now. With that bottle there, the coolant, as it expands, shoots into the bottle; when it contracts, it sucks it back in, and you can increase your cooling capacity that way. You don't need the air in the radiator you used to have.
