I was driving to school today and I noticed my car was runnign slightly higher then were it usually is (the gauge is usually perfectly level).I take my car to get something to eat down the street at break and when I get back theres a pudle under my car. I figured I should take it home so I get a block away and the gauge is almost in the red. I pull over real quick to let it cool then try again. I make it down the street and the gauge is moving in and out of the red. I park again and check the coolant level and it looked fine. I release the pressure on the cap and there is no coolant in the radiator:aigo: .I poured the overflow can in the radiator but it wasnt enough.Then I notced a wire hanging and a loose connector and it was my birdcage light. I walk to mcdonalds and get the biggest glass of water to put in but it wasnt enough and they wouldnt give me anymore. So jump my ac fan switch and try to go down the street to my old work. I got everything full of water then drive home it ran cooler then it ever has but the birdcage wont go away.Maybe thats why it was disconnected. what could have happened? I know everyone is thinking BHG but I checked the oil cap and the dipstick and they looked normal. I would check the oil and the water every other day but I never opened the radiator to check. Maybe my cap is not funtioning. I know it need s to be replaced now but what do you guys think. Sorry about the long post.
