Adding coolant to my car?

I have a Ford fiesta ghia and I put coolant in the car on Sunday and by today (thrusday) it has already finished and I haven't driven it. Is there a leak somewhere, because I can't see anything leaking…
And is it safe to drive…

No matter how swagged out an ant is, its probably not a good idea to add to a car.

  • Adding a hitch to a 2001 Ford taurus SE? I know this isn't ideal but is it realistic to pull 1-2 canoes on a small trailer using your Ford Tarus SE?
  • 2002 ford taurus coolant bubbling out of coolant tank cap? Coolant is bubbling out of the tank cap on my taurus. The coolant is a bit over the fill to line. The coolant is the normal green color. I don't think it having a bit of extra coolant in the tank is doing this. The cap itself maybe? I just bought this car and it didn't do this until today.
  • Can I save money by adding hho to my 1990 ford ranger? I always see these water generators online that claim if you add this to your already fuel burning vehicle it would make it more efficient. I love my little ranger but gas is so expensive and I drive long distances. It just doesn't seem like it could actually work or more people would be doing it right? Are the kits hard to put in? Is it worth my time/money? Will I actually save or is this just what they are claiming?
  • I dropped something into my car's coolant reservoir? I have a 2008 ford mustang. Yesterday there was a coolant level low light on, so I went to my nearest dealership and picked up a gallon of coolant. While pouring the coolant into the reservoir, a piece of foil (the foil seal you break when you buy it) about the size of a quarter fell into my reservoir. After an hour of trying to fish it out and find it, I gave up. Today I tried again but the piece of foil was not there anymore. What should I do?
