coolant

[blueballmp3]

man it looks bad im doing a coolant flush and its almost red, not in that good dextron color either its rust! I recently had my motor swapped cuz I sucked water up in my engine I think somethin is really wrong here any guess?

Did you get a used motor? Something could be wrong with it. Did you do a full flush when you swapped? By full I mean running water through the whole system, after you drained the existing coolant, there could have been leftover junk from the first engine.

Did you get the engine from a salvage yard or similar? If the motor was left outside for a long time or improperly stored there would definitely be rust in the engine. If that was the case I would be more concerned with rust forming on the cylinder walls, which might have caused some damage on initial startup. As for the coolant rust, try draining the coolant and flushing it a couple times with distilled water as SilentSno said until the water comes out clear.
