Ok I've posted about this before but now I've been trying hard to find out what the problem is. I've got a coolant leak some where and I can't find it. Its a small leak causing me to add a coupld cups of coolant/water about once a month. The strange thing is the coolant low light will be on and then after the car warms up and idles a bit it will turn off. I've tried pretty much everthing I can think of to find the leak but can't. I've set down cardboard and let it idle for a while and searched the water pump looked for liquid/smoke out of the tailpipes and nothing. I'm thinking now it must be the head gasket but it was just supposedly replaced by ford the day b4 i bought the car 3 months ago. Ideas?
