2003 Honda Civic overheating and radiator has muddy substance
Yesterday my car oveheated all the way to the top and when I open the engine brown muddy substance was coming out of the radiator. I took it to the mechanic and he flush and clean radiator fill it and took the thermostat out. While driving home after driving for about 20min. it started to overheat again. Please help me out and tell me what should I do to fix it??? Have to take it to a different mechanic now.

Is the radiator fan working?
Check the upper section of the radiator where the plastic and aluminum welded that's the section where coolant start to leak.

Could you possibly take a picture of the "brown muddy substance". I would guess it is probably oil mixed in with the antifreeze and the pump is cavitating the solutiong causing the two to mix.
I would say head gasket/cracked head or block.
Maybe pictures will help us diagnose it though

He already said that the oil wasn't mixing.

Read again, he said he checked the OIL and it was not mixing. You can blow a head gasket and mix the oil with the coolant in the radiator/cooling system. To me it sounds like he checked to see if the coolant was mixing with the oil in the oil pan. There is a difference between the two. Yes, oil and coolant are mixing, but he said he checked the oil and there was no mixing, but there sounds like there may be mixing in the coolant.
So again, if we had some pictures we could get a better idea of what is happening to the coolant. If he just had the cooling system flushed though (so fresh coolant) and 20 minutes later it is overheating and the coolant is muddy again, than I am almost 100% certain that oil is mixing into the coolant. There is not much else it could be.

You would see a mixture of coolant in the oil, if the two were mixing at all. There's more pressure (at certain times) on the coolant side of the system, than on the oil side. So coolant would be forced into the oil. At the bare minimum, you'd be able to smell the coolant mixed with the oil.

I agree... It is more likely, but it is POSSIBLE for the oil to mix in the coolant without seeing the sign in the oil (yet).
So unlikely yes, but I was just throwing it out there since I cannot think of anything else that it would really be.

Its a headgasket I'v had this same problem for 6 months now and its everything you've just explained i had my friend who works at a smog shop run the wand thing to the radiator and it read Hc's in it which is what should come out of your tailpipe not radiator

I'm willing to bet that the muddy **** he's describing is that radiator stop leak that they sell.
Here is what you do.. do a through flush... you might want to take out the radiator and run water from the bottom to the top also.
Get a new t-stat, fill the system with good quality antifreeze. 50/50 mix and bleed the system.
there is nothing wrong with dex-cool stuff as long as you change it periodically.
This is all easy stuff. get yourself a manual and try it out.
Good luck.

Gotta admit, that's what i thought too. Something like Bars Radiator Seal.
