The interior heat works intermittently. Regardless of how long I let the car sit at idle from a cold-start, I turn on the heater, watch the VSV open the heater valve and yet I get no heat into the interior. The most disturbing thing is there is no hot coolant flow through the coolant line that goes from the back of the cylinder head to the heater valve. ??? If I get into the boost, then sometimes the heat starts flowing into the heater core and I get fluid moving through the rear heater hose. I have burped the cooling system several times. The car has all new coolant hoses, a new Toyota water pump, new thermostat and a new Fluidyne radiator. Any ideas?
