1985 Westy, 1.9 with new right side cylinder head. Driving back from my apartment last night it was actually getting a bit chilly so I turned on the heat. When I did the cylinder head I replaced the water pump, thermostat, and temp sensors. Prior to that the van had always run cool and heater output was on the weak side. Now the temp needle sits just a little north of the LED, still touching the LED, but just a little high. Anyway, last night the heater output was very hot, but for about 10-15 seconds it turned cool then hot again. Does this mean I still have a bit of air in the cooling system? I'm thinking maybe yes.
