I drove my son's newly purchased Vanagon to work today....the front heater
was only producing warm, but not hot air eventhough I had the heat control
on full hot. The rear heater was producing slightly warmer air. When I
drove slowly the temperature rose slightly. The temp gauge was sitting dead
center when the engine was warmed up.

Is this warm air normal? If, not what can I do to get more heat...the kid
is taking the Vanagon to Rochester, NY in January. Does the cooling system
need to be bled?

Thanks in advance.
