Hey guys,
Bronco has been running hot lately, so I checked it out this morning and found black sludge in the radiator. It looks like it is only in the radiator, and only on the top half or less of it. It is stuck to the walls of it (maybe why running hot?) and no where else. Not in the hoses, thermostsat housing, manifold, etc.
I am not sure if it is oil, no loss in power, seems to run fine otherwise, the engine only has about 2000 miles on it. I drained the coolant, no oil anywhere, looks very clean and clear, no evidence of oil.
It is an all aluminum Be Cool radiator so I thought maybe something is reacting with the aluminum? Any help is much appreciated. Thanks
