Radiator Rust & Coolant

Ok, so I noticed my coolant was out... completely. I look in side the radiator cap to find goopy rust and flakes of something. This concerns me. Since it "appears" to be empty I guess now would be a good time to do any maintenance on it. I haven't had any problems with it running hot.

Suggestions???

flush it while you're at it. When was the last time you did that?

Using a flashlight to look inside the radiator via the radiator cap opening, how bad are those "flakes" and do you see any serious white build-up of hard water deposits around the cooling channels? If it's not bad, I might use a radiator flush but I'd probably just drain and fill it with fresh coolant. If you buy the kind of coolant you mix water with, be sure to only use distilled or demineralized (the same thing) water which is sold by the gallon in the grocery store for maybe 50 cents per gallon. Using distilled water will prevent hard water deposits from forming in the radiator which can lead to cooling problems.

A full system flush wont be a bad idea.

I didn't see any white mineral deposits, everything just looked "muddy". Flushing the system sounds like a good idea.

How exactly do you do a full rad flush?
I have a Hyundai I need to do that to, lots of orange sludge inside

There was a good write up.. basically all summed up, you gotta clean all the coolant out, and run new fluid thorough it continuously while the engine is running. There was a write up of a guy using a T pipe and a garden hose to do it. He simply pulled the upper radiator hose, found another one same diameter (about 2" of it in lenght) so now he has a T pipe with the coolant hoses going straight through and in the other opening he connected it to the garden hose. He opened the radiator and turned on the faucet. And then turned on the engine. Hoses gotta be clear though so you can continuously see that there is enough water from the garden hose than the water thats coming out from the drain plug. He got as much as the coolant out and then flushed it like that. This way it cleans everything out with fresh water. Dont forget to run the heater on too so it cleans out the heater core too.
