if your coolant level was full last year and now it is empty????
how as it a month after last year??? how often do you check it???
you should check it each time you gas up and add what it needed....

last year, you should flush it out and put some good old Prestone in it
and dont worry about it....
I asked the mechanic again what exactly did the scanner read. He said the
left bank reading was lean. He also mentioned that cylinder 6 is miss
firing (I assume that the left bank is cylinder 2,4, and 6). I replaced
the 6th cylinder spark plug. And at first it seamed that starting the
van was a lot easier. But next day engine light was back on and it takes
about 5 tries before the ignition starts. Question can ignition problems
have anything to with this lean reading. Can it be related to the miss
firing problem? If so, If so difficulty starting especially in the
mornings, does that give you a clue if it could have something to do with a
bad sensor as opposed to miss firing problem? I would like to address the
mostly likely problem first or the easiest solution first.
btw: I year ago I had sugar in the gas tank, so I had the tank replaced.
And added some fuel injection cleaner in the gasoline. I have had no
Your leak was probably leaking on the side of the engine and burning off
before it dripped on the ground - quite a common occurance.
