Overheating issue

[mopar951]

Hi everyone I’m having trouble with my 69 coronet it has a 318 and the trouble I’m having is it’s overheating on trips that are like 20-30 miles it has a new thermostat new upper and lower radiator hoses and new coolant I took the rad out a flushed it and nothing really came out it does have a newer rad cap I have a video of what it’s doing in the radiator with the cap off but it’s just swirling around it’s not flowing any insight I was thinking water pump?

To be sure the radiator is not the problem it needs to be rodded out by a radiator shop.
They take the tanks off and clean out the core properly.

When you say swirling around, is it not doing that at idle? Or just at throttle?

Just a throttle, but I noticed my lower radiator hose is collapsing under throttle so the spring is not in it

That can also indicate the radiator is blocked.
