The bubbles in the radiator test isn't really accurate. If you want accuracy, do a compression test or better yet a leakdown test. They rent out the testers at most parts stores and you just need an air compressor.
What do you mean you added antifreeze mix for the winter though? what did you fill it with before?

Tested the cap already, its good. I think the problem is the water pump. This morning I let it idle for a while (till thermostat opened) and then got on the throttle while watching the coolant. The coolant is not circulating like it normally does. In fact, it doesn't look like its circulating much at all. I can tell the pump is definitely making a faint noise now. Sounds a lot like the old OEM pump did before it went out (which lasted an amazing 165,xxxmi.). I don't want to replace the pump with another p.o.s. that will just die in another month. I'm thinking of getting a Hesco unit: http://www.hesco.us/products/7967/hi...-pump-hf58-455 I've read mostly good reviews about them. Thing is, everyone says they have a lifetime warranty but I don't see that anywhere on Hesco's site. I don't care if it is high performance or not, I just want it to last like the old one, any suggestions other than Hesco?
Also the plain water isn't going to help with rust, especially with an iron block and head. Regular 50/50 antifreeze will stop that.
