Checked cold and how do i get the coolant off the plugs? I just got this car 2 weeks ago from a buddy who said he didnt want to deal with it...hes not mechanically inclined at all. So ive never touched the coolant except today when i drained the radiator. The overflow is what i looked at and it was at the good level.Coolant color has nothing to do with coolant leaks into the combustion chambers! You should have a hot & cold level mark on the reservoir, how did you check that, hot or cold? Have you ever added any coolant? It sounds like you have coolant contamination on the plugs and in the combustion chambers. The plugs will not fire when coolant soaked.
