Combustion gasses in it from a leak crack gasket. Detergent remaining in the block used for Oring assembly on a wet sleeve engine. Smell is a givaway, and kits are available to check for combustion gasses in coolant. JimN

I got this info off of a site: http://www.eetcorp.com/antifreeze/antifreeze-faq.htm#q47

Why does my coolant foam?

Foam in coolant can result from trapped air in the system, a leak on the suction side of the water pump, an improperly functioning water pump, low or no coolant in the coolant recovery tank, or the lack of a coolant recovery system.

Foaming may also be caused by a lack of anti-foaming agents in the antifreeze. Arctic Blend® antifreeze products include an antifoam chemical in every formula, and each batch is tested before leaving EET’s facility to ensure the ASTM standard for foaming is satisfied.

Last time I had the foaming coolant thing happen, it was a blown head gasket.

Check for a blown head gasket using a cooling system pressure tester. A bad gasket isn't the only thing that might cause foaming, but if that's the problem it needs attention.
