output. Turning it on to high heat in Seattle's 50-60F weather, the air coming
out seems to only get warm, not nearly as hot as my previous 1987 Nissan van.
I am wondering if this heater is partially plugged or the engine thermostat is

the Scion (still makes me sick to think about it...).
I had the same heat problem, and in trying to remove the water pump I
broke the idler pully bolt off in the block. Hey! I TURNED it the way they
