Default Re: Cooling system help needed

What happens if you drive with the radiator cap "loose" with no pressure?

Are your radiator hoses literally collapsing, restricting flow?

When you remove the radiator cap and let the engine reach operating temperature, can you see water flowing thru the system?

Could your thermostats have turned sideways inside the radiator hoses, restricting flow.

Remove thermostats and see what happens? Immerse them in hot water and observe the temperature at which they open.
