Did you replace the thermostat ?

Because if you let your vehicle run for 2 hours with the cap off and it did not over heat you definitely have a problem vehicle is not building up pressure.

Sounds like the thermostat is stuck open

I have changed 2 of the t stats

Sounds like you have a blockage in the cooling system try doing a cooling system flush. Prestone Super Flush is really good. If that does not help may have a clogged radiator that needs to be replaced.
