when my headgasket went, it did sorta the same thing. blew cold air all the time, and the temp went all the way to red line. then the lifters started hitting.

Sounds like something's blow, likely you have a coolant leak, engine got way way too hot and now you've fried something.

Just found out the radiator was leaking but i added water before i left to work this morning.

when my head gasket was blown, coolant was leaking into the cylinder. i was losing coolant, and this put air pockets in the system, and when the air pockets passed the t-stat, the temp showed up as overheating. i don't think anythings fried. try taking off the coolant cap once and letting it run. when my headgasket was blown, the coolant always spilled over the top when the cap was off...

how do you explain the knocking?

what they told me is this: coolant gets into the cylinder, causes a misfire. the knocking is the lifters hitting which is caused by the misfire. at least thats what they told me.
