Every few weeks I need to add coolant to my '98 C5. I've been told by weo
shops there no leaks but every morning three's way too much water in the
driveway. What really bothers me is when I go to add water or coolant even
when the engines cool and not running when I fill it to overflow. the
coolant is all foamy and aerated. Almost milky wit with tiny bubbles. The
temp never goes above normal and runs fine. Should I flush the system?
Could some hwise guy put soap in the coo lent reservoir?
I would pull an oil analysis sample asap to make sure there are no
internal leaks letting coolant into the engine oil. These are very
common on GM V-6 engines. You don't have a V-6, but I would check just
the same. It is possible that the symptoms you describe could be
caused by a failed head gasket.
www.blackstone-labs.com is one of many companies that do this kind of
work. They will send you a sample kit. You send them the sample and
about $20 and you will find out if there is contamination.
Easy and cheap and well worth knowing.
There are many other labs which provide the same service.
He should be able to confirm something quicker than mailing off a
sample since he has water in the driveway. Maybe he only has a cracked
reservoir or a leaky hose. Crawl under and look up with a light.
I would flush it and hope.... Otherwise you are giving a classic
description of a blown head gasket.
One test is to carefully warm it up with the rad cap off and watch what
happens. If smoke also starts coming out the rad opening, it is the
gasket for sure.

If you are loosing antifreeze it is leaking. If you see antifreeze on the
driveway it is leaking. If you see bubbles and foam in the reservoir chances
are good the head gasket is blown. I don't know what weo shops is but since
you apparently know anything about engines I would find a qualified mechanic
to check it out before you have to replace the whole engine...
bad maintenance. First off the 98 Corvette has a low coolant warning
that is very sensitive and will even come on if you park on an incline
and you never mention that it came on. Adding coolant because you see
to much water on the driveway is the first step towards disaster. What
coolant was added, if it was incorrect for a GM vehicle you have
contaminated the coolant system. Is it not possible that the two shops
that said there was no leak was correct? Then you added more coolant
then it was designed for? When you say the temperature never goes
above normal could that mean the coolant is at a proper level or a
safe operational level?
My first suggestion is to take it to someone that knows something
about cars and keep your hands off of it. You have come up with more
problems on one Corvette than I have had with the last 6 that I've
Knock off the cross posting, if you want another opinion post it to
that group by it's self. If you just need attention post it to the
proper group, now back in the black hole. Of course if you post your
crap to enough groups it will come up here again. Then I'll have to
block those people to stop your drivel.

I see water in the driveway but it doesn't smell like coolant. It's clear
like water. When I add water to the reseviour foam overflows even without
