  Could just be an aging water pump impeller causing cavatation?

Joe,

I've heard of looking for bubbles in the coolant, and I used it once to 
reject the purchase of a car. As to whether it is a real indicator of a 
blown head gasket or not, I do not know for sure. I assume the funnel is 
to get the water level up to where you can see the water surface, rather 
than being down in the top tank where it isn't as easy to see.

Peace,
Pat
