Greetings. I've notice my coolant going down consistently for awhile, but only now got it up in the air to flush the coolant and do the front brakes. This is what the coolant/coolant cap looked like: http://imgur.com/gallery/wAVwH

The cap was covered in sludge. It leads to suspect there to be an oil leak into the coolant system. It could be leaking at the radiator or at the engine oil cooler. Is there any good way to test which is failing? I'll have to check the transmission fluid, the oil is jet black. There is an oil leak somewhere around the oil cooler, and the upper radiator brackets have recently failed.

Are there any good tricks to cleaning a coolant system after a leak like this? I've flushed it clear but I was thinking of dumping some sort of cleaning agent in there with water and running the engine for awhile.
