Rust is from Iron. Aren't the stock radiators copper?
I'd still say the discoloration is either from a head gasket/egr leak or corrosion of the block and heads. Replace/Flush the fluid and see what happens.
trust me most likely the rust is from the radiator. I had the same experience with two of my mustangs. Each time I replaced the radiator and it fixed the problem. He can try flushing the radiator but if there is substancial rust damage the rust will only return when he refills the radiator. Fix the leak and try the flush. Check your coolant after you refill for awhile to make sure the discoloration does not return. If it does then you know the radiator is garbage. If it was his head failing he would be burning antifreeze and getting white smoke coming out of his exhaust. Also check your dipstick and radiator for a manase type substance which would indicate oil and coolant mixing together if so it may be your heads.
again good luck
again good luck

Iron produces rust, copper produces copper oxides (which are green like the statue of liberty). But what do I know I have had like 20 beers at this point. Then again I do test structual materials for aerospace applications.
Who cares, Beer is cool.
Yaaaaaahoooooo!!!!!!!!!!!!!
I have seen coolant get into the exhaust with no backward mixing. IE there was no oil in the coolant and no white smoke in the exhaust.
I think you have soime cooling issues, and all I can do is throw out some ideas.
Hope it isn't as bad as I have suggested. but if it is at least it won't catch you off guard.

The rust comes from the block. An engine block is iron. A radiator cannot "rust".
It seems to me that there is a pin hole leak in one of the egr hoses, as previously mentioned, and that it squirts under load. Thats why you have a brown spot on your hood. Otherwise the coolant would leak downward. The only way to find it is to fill the car with water, get it hot, and check the hoses with car running. You might even want to give the car a little throttle to create a little pressure in the system. It's no big deal.

If it were me I'd find the leak first, fix it, and then worry about the color of the coolant provided there was not a serious problem involved.
If indeed the coolant was changed in the last few months, there is no reason for it to be that brown - even with well water. That is what it looks like when oil gets into the water and is well mixed. It turns into a thick light brown slurry. What does that brown stuff smell like? Oil? Coolant? Both?
I agree that it looks like the heater hose fitting might be leaking but make sure you do not have oil in the water or water in the oil first. If it's losing water (3 bottles at a time) and you drove a long way there's a chance you overheated it and either cracked a head or blew out a head gasket.

I don't know that the water pump generates that kind of pressure on its own. Combustion gasses can pressurize the cooling system though. I won't mention blown head gaskets anymore though, because I don't want to jinx you.
Let us know what happens.
