Overheating #3 Options

[Araykhel]

I'm back to the boards and at the mercy of you clever bunch once again. Right, so some background: Prior to last February I was overheating at the most random of times, coolant disappearing and the like. Replaced a thermostat, checked hoses, added coolant, and made sure never to drive any longer than emergency would have it when I got into the red. That evolved into a full blown leaking water pump and thus I fixed the issue on my own after learning how (thanks for that).

Now, fast forward three/four months since I changed the water pump and my engine overheats, I check under the hood and there is steam blowing out of the radiator cap. I did a flush (probably horribly) when I changed the pump and made sure the coolant levels were great but here I am with an empty reservoir/ plenty to add to the radiator.

When I drained the coolant last month there was no mixing that I could see, and just yesterday after a 40 minute drive I had good temperature but my radiator was spitting fluid from the "sealed" cap.


Help me you magnificent gear-heads.

do a leak down test, and check the underneath the oil cap to see if theres any milky substance on it.
