70deg is to low should be up over 83deg - is the rad getting warm all over I’d suspect someone’s removed the stat but should still get up there - how long have you driven it for? It should get to optimum running temp fairly quickly hence the reason for the thermostat.
you shouldn’t hear the standard pump over the engine so would suspect if you can I’d be replacing it as most likely on the way out.
