coolant tank leak

The best method I have found, is park your car wher the passenger's front is slightly elevated, take the cap off(when cool obviously), fill tank aprox half way. Start the engine leaving the cap off. When it reaches norm operating temp, let it idle a few more minutes, maybe 10 or so. Then let it cool down, refill tank to proper level, recap and drive.
If when you first fill and idle w/out the cap some coolant "burp's" out, thats normal, it's the air escaping.
Was the tank run empty? That would cause air to get in the system.

I would think that even just a crack would affect it pretty severely. As it expands and contracts with heat changes and the pressure increases, how can it hold the pressure?
As it flexes, pressure escapes, coolant escapes, air gets sucked in, system is out of designed operating parameters...................What is to be expected?

This is the Bleeder valve that should be on your radiator.

The resevoir does not bleed actual air off the system. Not correctly anyway.
Fill it up. Rev engine to about 2000 rpm for about a minute. Open bleeder screw
pictured above to bleed out air and close immediately. Continue doing this until nothing but coolant comes out. Then take it for a drive and try again. I have done many vehicles this way. An Airlift is better but this will work too.
