Brown Chunky Antifreeze???

Really? Do we have to go through this again? Switching to ethylene glycol, (green) does not cure the problem, it creates a much larger, more expensive one: Water pump failure Flush it out, clean it out, and put Dexcool in it. You're asking for trouble using ethylene glycol, and you'll get it.
In the link you posted, it talked about new engine technology, with aluminum alloys being one reason new coolant was created. Are our engines built like that? I thought they were cast iron block and heads, and I assumed cooper radiators and heater cores.
I guess the difference is in the water pump seals, though, and not in the other engine seals? Anyway, I'm not trying to argue with you, just wanting to understand more before I do something that might cause problems down the road! That water pump was such a PITA to change once, I don't want to have to do it anytime soon!

Sorry just trying to gain a little information, didn't realize I couldn't ask a question if its been asked before.

Well, its Oil in the Antifreeze
So I was having some overheating issues and I decided to just flush the radiator and heating core and refill it with new antifreeze. After draining the antifreeze I got a surprise. Most of it was just oil. So my question is whats the problem? And why is there oil in my antifreeze?
I attached a picture of what the "antifreeze" looked like right after I flushed it.

The first place I would look is the engine oil to see if you also got antifreeze in your oil. If not the next place I would look is the radiator, if you have an oil cooler which is two oil lines that connect on the drivers side of the radiator. It would be an internal leak. If you do have antifreeze in the oil then I don't know where I would start to look since it would most likely be an internal engine issue probably involving the head gaskets or maybe the intake manifold. I have never experienced oil in antifreeze but have seen antifreeze in oil.

A seperate oil cooler will stop the oil from contaminating the coolant BUT, the leak in the OEM oil cooler will now allow coolant to get into it. You could plug the fittings on the radiator but, these radiators have a habbit of cracking the side tanks, so you might as well fix it right and replace the radiator. Probably less expensive, and definitely less fooling around
If/when coolant contaminates the oil on this engine, the first place to look is a leaking lower intake manifold gasket, very common problem.
