Vengts blow coolant smell all the time. I have closed the vents but it still smells. The coolant reservior looks low but isnt, however, fluid is dark.
Can I drain, flush and refill reservior?
What about antifreeze, would it need to be filled or flushed/replaced?
New to working on trucks do need some serious help. I can change oil and thats about it with out F%$KING something up. Thanks
