Question about 1999 Mercury Mountaineer
Hi I'm Peter, Ok maybe we'll be lucky and it won't be too bad. The biggest thing is we need to find out EXACTLY where at the front of the engine. There are several places it could be coming from, so let's make sure the water and engine aren't hot right now. That brings up another point does it leak only when the engine is hot or all the time even cool? Get some safety glasses on and maybe make sure NO ONE can get in and start the engine while you are laying under the front end looking for the leak. Open the hood and begin your search it could be coming from a heater hose or from a radiator hose. You stated it was coming out of front lower part of the engine. You do have a lower radiator hose and there is usually a drain plug for the radiator. Your water pump is located on the front of your engine and has two hoses an inlet and an out hooked to it, At this point I would focus on the water pump area and look for any stains where water may have been dripping and running down for a while. Water pumps have a little hole on them sometimes on the top and sometimes on the bottom it really depends on makes of engine. When a water pump does out the bushing or bearings that the shaft ride on has a seal so when they wear out the shaft will press on the seal allowing water/coolant to leak by and run down the engine. Don't get the coolant in your eyes if you do flush it with water and consult your doctor. Remember also that coolant/antifreeze has Ethylene glycol in it that is DEADLY to animals. It as a sweet taste and dogs,cats, etc. will lick it up off the ground or just lick the ground where it is spilled. A common reason water pumps go out is an engine may have a little pinhole leak in a hose or radiator and someone just keeps topping off the radiator with water diluting the coolant. Where this becomes a problem is the coolant has chemicals in it that prevents oxidation of the metal parts of the engine and radiator so the radiator and entire cooling system clogs up or erodes and you have ruined the radiator ,heater core, thermostat, etc. These chemicals or additives as the producers call them also lubricates the water pump and protects the seal. Running just water in an engine is throwing money out the window. If you do need to get another water pump and install it I highly suggest changing the thermostat also while you have the system drained and hoses off. It is a simple procedure that will save you heart ache later. I hope I haven't given you too much information but the more you know the better you can take care of your vehicle and your pocket book. Let me know if you need any thing else and also what you found to be your leak, I would love it if it was jst a bottom radiator hose. Happy Easter

DeWayne: First WATER should never be in auto engines. But you need help. the water pump is there and the seals of it could be bad. MAKE sure the water is not skeeting from a hole in the radiator thereby fool your view.
