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.

also make sure your fans kick on, my old 5s overheated once and it ended up being the fan switch that goes on the radiator. it wasnt completing the circuit for the fans to kick on.
to confirm do a leakdown test, and when you do it remove the rad cap, and if your head gasket is bad as u do the leak down test youll see water spitting out of the radiator. or it will begin to buble. honestly thats the best way to do it. it will cut to the chase and guessing on what it could be. imo

Fans work fine, though I see the importance in checking. That was one of the first things I checked last year when this all began. I managed to get a great estimate on replacing the HG since I am not capable to do it on my own something like $400 dollars for parts and labor and $150 dollars to have my heads machined.
