yup a whole res, well you could see it wayyy down in there but it was almost gone..we never noticed anything leaking from the car (cause i always check that) we never noticed white smoke(billowing or over wise) but then again i didnt think there was a proublem that needed to be checked on in that department, the car ran fine the whole time. well besides the fact that for about a full week it was eating anti-freeze like it was something to do. I refiled everytime (which was about a couple times and topped off once), we would be able to get it going and drove it around for a while thinking whatever it was would kinda fix itself, then a few days later it just wouldnt start at all no matter what we did. It seemed like if we let it sit over night the proublem would take over again and we'd be back to square one(no start) for no apparent reason. I checked all fluid levels and they were good,eccept anti-freeze would be alittle lower then it was before(this is after the anti-freeze bindge)
