Answers :

Look at the area where you park. Is there any fluid under the car that is not oily but rather is slick and has a sweet smell - yes, you wil have to stick your finger in it to see. If you find this type of fluid, you have a leak from somewhere in the engine compartment. Judge by the amount of fluid whether this is a major and potential calamity. (Lots of antifreeze could mean a bad hose or a bad water pump.)

Once you've checked for leaks, check the plastic reservoir that holds the radiator coolant overflow - is there anything in it? If you found alot of fluid on the ground, odds are that the reservoir will be low. If it is much below the fill line, add some water and coolant (50/50 mix) until it is back to the fill line.and check it for awhile to see if it needs more after you have driven for a bit (keep the coolant with you in the car just in case.) When the engine is cold, and as you are checking the reservoir, remove the radiator cap by pushing down on it a bit and turning it in the direction shown on the cap itself. Look into the radiator with a flashlight to see where the fluid level is. If it is more than 2 inches from the top, add a bit of coolant/water but not up to the top. Replace the cap firmly and add coolant/water to the reservoir cold level mark.
If that all looks fine, you may have a bad water pump, a plugged radiator, a week cooling fan or a bad thermostat.

Good luck.
