Let'* step back a minute

You have coolant loss. How much over what period of time. It'* enough to notice therefore we should be able to help you find it.

Did you recently drain the system or change a thermostat...any work that has been done on the car?

Does the engine run rough as if it'* burning it, any signs of white smoke out the exhaust?

And WELCOME ... we will help you get this one figured out...

One thing I noticed, that not too many people seem to point out, just before I had my "incident" involving coolant....

Wild temperature fluctuations. Does your temp gauge stay fairly steady (normal fluctions) or does it go berserk on ya? Much hotter when slow, and way cooler when moving?

Default Cooling System Problems

I'm losing about half the amount in the tank in about one week. I had my mechanic look at the car which included checking the oil and he found no leaks or evidence of coolant in the oil.

Default Cooling System Problems

I did forget to mention that recently a plastic fitting that goes in to the manifold broke and was replaced. This caused major loss at the time but the mechanic re-filled the system at the time of the repair. I have enjoyed the opportunity to discuss this problem and will return when I return from the holiday. I wish everone a happy 4th.

How long ago was that? If quite recent you could have an air pocket in your cooling system. Check out this thread regarding a similar issue, and about 3/4 of the way down the page is a post by Bill Buttermore on how to fill properly and get rid of the trapped air.

The plastic fitting for clarification is the coolant outlet. Found on the waterpump end of the motor in the intake manifold with a hose running from it to the water pump.

Happened to be my first problem ever enountered with a B'ville. The plastic rots and wears over time. Most replacements are metal tubes and never have any more problems.

Did you end up overheating when you lost the coolant?
