    Drive at 60 mph?
    How many RPM are you spinning at those speeds, maybe the truck is not spec'd out for that speed.

    get yourself one of those digital thermometers and start searching for hot spots, and sometimes they close the heater core off to cut heat in the cab, cutting amount of fluid cycling.

    What model of Volvo do you have?
    Follow the two heater hose that go into the firewall, the heater core will be there.
