When I installed a new radiator a few months back, I thought I had got all of the old rusty water out of the cooling system, but apparently not... I drained everything to install a new water pump the other day, and noticed that the coolant was still a bit brownish.
So I flushed everything with clean water until it drained out totally clear... but looking down into my radiator I can see it's still a little grungy bit inside. The inside of the old water pump and thermostat housing were also pretty coated with rust, so I'm sure the coolant passages in the engine look the same.
Should I run something like Prestone Super Flush through the system to try and really clean it out? I'm sure most people's cooling systems aren't totally spotless inside, and I'm not having any cooling problems at all, but I believe in doing a job as throughly as possible.... then again, I'd also hate to dislodge a bunch of old rust in the system and have it clog my new radiator or something, so I don't know what I should do... Opinions?
If I should flush it out, is the Super Flush a good product to use? I assume this will be safe for my aluminum radiator since it doesn't say otherwise...
