About 2 or 3 months ago, I took this 91 Ciera to a radiator shop to
get a radiator leak taken care of, since I seemed to be losing
antifreeze from the reservoir, even though there was fluid in the
radiator itself. It was a newer radiator, but the found a leak and
repaired. About a month or so later I'd gotten a tune-up and went
driving around for a while and noticed a few days later that there was
a thick antifreeze smell when I'd walk by the front of the car and the
antifreeze in the reservior was almost empty, again.
Take it somewhere and they check it out, find some leaky hoses, and
they replace the lower radiator hose and the bypass hose: End
result--thick antifreeze smell nearly gone from the front of the car.
A few days ago, I get out of the car and notice a slight antifreeze
smell when I'm bent down by the front of the hood. Nowhere near what
it was, but I crack open the hood and look. There was a lot of grime
on various parts of the top of the engine and--given the amount of
antifreeze I'd been losing from leaking hoses--I'd assumed that most
of the gunk and grime was caked on from those.
With that, it appeared along the intake manifold gasket* (where there
was a collection of grime) there were a few droplets of antifreeze.
So today I pulled out a rag and wiped off the area, cleaned off as
much as I could with only elbow grease, and noticed after it cleaned,
it seemed that there was a slight, slow, sweat of antifreeze from
along the gasket. Not a lot, maybe even invisible if I weren't
looking and the engine was still a little warm from running for five
minutes. Car seems to run all right except for that, but when I was
letting the car warm up last night I noticed more white smoke from my
exhaust then seems to be attributable to the cold weather.
Additionally, tonight when I was driving and stopped the car after
about 100ft of driving to get out and get something, I noticed an
bitter, almost a rotten rubber, kind of smell in the air--seemingly
from my car.
Both the reservoir and the radiator seem full and very green. Oil
dipstick seems to be almost 'new' oil color. (Last done three
months/1000 miles ago.)
*(Fairly sure it's the intake manifold. Had to go to the library to
look at a Chilton's to see what the part was from my recollection.
Unfortunately, by the time I'd gotten to the library it was too dark
and cold to reexamine the engine to double check)
Do these symptoms sound indicitive of something?
