surely if you know it should be hot after a drive and the rad and pipes are cold you know you have a airlock and gauge is correct. I would get a leak test...You continue with air locks you will most likely get a 'hot spot' and get a head gasket issue.
It sounds like air is getting in. Hopefully not exhaust gases.
