The radiator has been flushed with an acid flush, also I have not been
able to detect any cold spots in the radiator. The last water pump I
put on, I did a test flow while the radiator was off, and volume
output seemed more than adequate. I also washed out the fins of the
radiator, but they really weren't that dirty.
I have thought about the fan clutch, although it seems to be "stiff"
when cold and "free" when heated up
I will check the ignition timing to make sure, but I check it "by the
book" each time I put a new timing belt on.
Thanks for all the input - sooner or later we'll get this resolved, at
28 mpg, I sure hate to give up on it.
