Had temp fluctuations... checked and noticed coolant is brown and muddy
Welp.... Past couple days, I've had trouble with the coolant temp fluctuating... figured it was something simple. Tonight, I opened up the radiator to find it HALF-FULL.... What coolant is in there is brown... and the inside of the radiator is covered in what looks like mud. Nasty.
Block is a Fiddy3. Doesn't APPEAR to be cracked in the normal places.... I have yet to notice a leaks, puddles, etc. Temp fluctuations were my only clue to this.
Also note that the oil appears to be normal...
So what've we got going on here?
Thanks Y'all!!!

Hate to say it but, it could be a head gasket. Loosen the drain plug and see if any coolant trickles out of there, hope not. Otherwise fill the coolant system up, and get the engine to operating temperature. Remove the rad cap and load the engine up to make some boost, while a buddy looks for bubbles forming in the radiator.

Hey Whit, I changed the coolant and removed/cleaned radiator summer 08...
What drain plug you talkin' about? The lower radiator petcock?
Another good trick for this is to leave the rad cap on and pull the rubber holse from the overflow tank and stick in a cup of water...look for bubbles.
The brown MUD-like substance is whats bothering me.... where'd that come from?
Could all this come from a bad cap? wtrpump? Tstat?
Thanks Fella's

No, on the oil pan.

If you do this, you must wait for the coolant system to build enough pressure to overcome the rad cap.
