Ok, im full of questions today!... lol.... Got another one for you guys.... Long story short, blew a coolant line a week ago fixed it, didnt refill the coolant, (looked like i only lost about 2 cups, so wasnt too worried). Drove home today, checked fluids, took off radiator cap, and i had foam in the radiator. Is this just because of how low it was, it had air in there, or is there another problem stirring up? Also, i fit helps... the radiator was flushed about 5 months ago when i replaced the water pump, and the engine was rebuilt 500 miles ago. There is no odor in the radiator except coolant smell, and I have no coolant in my oil.
