I have a 1986 mercedes 300e it was running fine until lately when I start to drive in the morning all of my antifreeze has leaked out from the bottom. Someone said it might be my water pump. But I have no problems when I drive it. But every morning there is a puddle of antifreeze on the ground under the car

You have a servere coolant leak on the vehicle. First get relation to where the leak is on the vehicle. Where does the puddle form and what components are in this area? Now open the hood and see what components are above your puddle. Check all your coolant hoses and squeeze them. Does coolant come out somewhere? Are there any buldges or splits in any hoses? Do the hoses look dry rotted? If the hoses look good move onto the area of the water pump. Check the inlet and bypass hoses coming from the pump? Are they in good condition? Next check the water pump? Does it look like there is corrosion around any of the hoses where they are clamped to the water pump? If so this is an indication of a coolant leak? Finally check the sealing surface around the water pump. Is the gasket leaking? If so this must be replaced. Check your radiator as well. If any areas look wet on the radiator, then you may have a radiator leak. Keep in mind that if you see coolant on the block near the head leaking, this may be an indication of a blown head gasket.
