New cooling system, still overheating.

Why would I lie about getting stuck on the side of the road a few times with my top radiator hose hissing like a tea kettle and my engine making crunchy metal sounds?

Everything is new and replaced within the last 9 days:
fan clutch
then thermostat
then radiator, radiator cap, water pump, top hose, lower hose
never have used a fan shroud

for proof I will upload pics of my old/original copper rad, the champion one that got rusted out as well as the new cheapy chinese made Murray one I bought from the 24hrs Oreilly (in Houston we have 24hrs Oreilly and Autozone) last week in a pinch as I needed to make it to work in the morning by 6am.


At first I was running 50/50 mix. But the wise azz that I am read on this forum that I could run pure water so I started doing that.
And that's when I got stuck in traffic for 90mins on the way home one day and it started blowing white smoke and didn't want to shut off.
I believe that is when I blew the gasket.
Next morning she started up and was fine for 6 months or so.
Then, about 2 months ago problems started happening again with water/coolant loss.
Then the rust
Then overheating.

I will pickup a infrared thermometer and grab some readings.

Any idea where I should take my readings?

You can run pure water. But you ABSOLUTELY MUST run a quality coolant additive that has lubrication, anti rust, anti electolysis properties. ALL of those properties minimum.

Your car did not overheat past 200 degrees just because it was running pure water. It got rust buildup and blockage or you still have some inherent cause of your cooling issue. And seems you still have it.
