I have repeatedly flushed the system, changed the coolant, and it still
comes out a little yucky. I know that coolant exits the overflow, but it
doesnt' seem like the overflow is even designed to return the coolant. If
it is, the closes radiator and opaque overflow dont' give me a good idea
of whether it's doing the job. I doubt it is. I have replaced the
thermostat several times attempting to solve this problem, but to little
avail.
What i do know is that my father's mustang had the same problem earlier
this summer, and was resolved by changing the radiator and renewing
thermostat, flushing, and changing coolant.
My concern is whether steam coming from around the spark plugs is a blown
gasket, cracked head or worse.
My other concern is trying to drive the car with any reliability in 100+
temps in Arizona. That's why I would like to have some sort of uprated
radiator, if available.
Thanks for reminding me of the little things,
Mike Jose
