BA 97 Overheating

So a few months ago, one day after work, I was driving home and heard a ping noise, so i pulled over and popped the hood. It was overheating and i opened the radiator cap and good deal of coolant came out. The coolant was discolored and seems to have rust in it.

I went to the store and got distilled water. It took me a very long time to get it home that night driving a few kilometres than letting it cool down for an hour or so. Rinse and repeat.

Basically what happens is the temperature steadily increases until it starts overheating. I took it for a drive recently and held the bottom radiator hose which seemed to be only slighly warm while the top was hot. Which would suggest its the thermostat is closed. A few minutes later though had some heat in it.

Other than that i suspect its the water pump, and the cooling system isnt flowing properly. What do i have to do to check the weep holes? Or is that pointless.

Also someone else had a look at it and said he thinks the head gasket is blown. There are some bubbles in the overflow tank, but i read this doesnt necessarily mean its blown. Is there any other way to confirm if the head gasket is blown?

Thanks for anyhelp.

The car is an Astina 323 BA '97 w/ 1.8L DOHC engine.
