I finally fixed my cooling problem !!!!!!!!!!

I have the same problem with my car heating up, I have tried numerous things...even a new four core radiator, flex fan, shroud, and high flow water pump. Still an issue when the temp is 90 plus outside, car temp just climbs when in traffic. I got frustrated and took it to a shop and they said, they couldn't find a problem. Never thought of the bottom hose with a spring, I guess I will try that...Thanks for the input.
