Why does my upper radiator hose get sucked flat?
Doesn't happen in the winter, but when the temp starts to climb like yesterday when it was 100 outside, the water temp is running about 200 degrees. Pop the hood, and my upper hose is flat. After the motor cools down a bit, lets say a couple hours, I'll take the radiator cap off, and will hear a release of air, the hose will fill out some. I'll top off the water/antifreeze level of the radiator itself. (the coolant tank behind the battery is worthless) and the hose is fine until 20 miles later, flat again. It's been doing this for a few years. And I'm figuring this has a little bit to do with my high temp driving. Especially on the freeway. New Gates hoses do not fix the issue. Neither did a new cap.
What's going on?
