I went to check (engine light on) and i was ask to come back very bussy. on the mean time i checked my radiator level and found the antifreeze dirty like some sort of oil type on surfes when you open cap is this someting to werry about? Thank's palunga

 

palunga,

How old is the car? Has the anitfreeze ever been changed? If not, I would suggest that you have the system flushed and have new anitfreeze added. I don't know if that's why you check engine light is on or not. A bos O2 sensor will cause the light to illuminate. Also, if you don't put your gas cap back on tight, this will cause the light to come on. Hope this helps,

David

 

I meant a "bad O2 sensor", not a "boO2 sensor) SOrry[&:]
