In a 1999 ford Taurus, 3.0 L engine, not the doh engine, just the regular 3.0 engine, the coolent does have a brownish tint to it. I've had radiator flushes every single year, but i still have no heat. i heard that flushing the heater core is different, so I'd like to know, step by step in how to do this correctly. My thermostat was changed yesterday, I've touched the pipes in the firewall(was told these are the heater core hoses) and one was warm(luke) and the other was warmer(more than luke), but i still have no heat, my heat blows like luke warm to cold, and it takes a long time to get up there.
