I was driving down the road yesterday when I see some smoke coming from my grilles, so I pull over and shut the car off. The radiator wasn't shot, so I just let everything cool down and bring it the other 1/2 mile home.
Afterward I open up the radiator and look at the antifreeze, antifreeze level is normal but there is MOUNDS of brown gunk and slime all over the place. I'm assuming a radiator flush will solve the problem, but just curious as to how this could've happened?
EDIT: I also heard an odd clicking noise when I first started the engine that day, but everything ran fine and it went away after I drove it a bit, haven't heard it since, not sure if that means anything.
