Re 1994 Ply Acclaim 3 lit.

My auto is losing prestone. This seems to have started just recently. Had
the radiator pressure checked, for any possible leak around radiator and
hoses and no leaks were apparent. There was a test done for the head
gasket
by analyzing the prestone in the radiator, and there was apparently no
sign
of this issue. There was also no sign of prestone in the oil. With the
engine running, I have seen a little vapor puff on the passenger side of
the
engine from time to time. I was advised that it could be a frost plug or a
water pump leak. The car has approx 180,000 miles. There is a sign of
leaking around the engine, but no apparent sign of prestone on ground. I
am
losing approx a cup or so a day, however, recently the loss seems to be
less
than that. I look forward to your comments on this matter. Thank you for
your help. Mike
