I hve water leaking from the rear of my engine on my 98 expedition
Hello moltn, quite often people completely fill their coolant reservoir, ( the plastic bottle with the cap that says, " coolant " ), If you haven't already, make sure that the coolant level in the reservoir isn't over the FULL line. When it is overfilled, and the engine runs for a few minutes, the heat builds some pressure and forces the extra coolant out through an overfill hose. That overfill hose usually drains, on the ground, in the general area your leak is comming from.
If that is NOT the problem;
Next, we need to find out if it leaks all the time, or, if it only leaks under pressure, ( when the engine is running and warmed up ).
Start the vehicle just long enough to back it up 2 or 3 feet and then turn the engine back off. Raise the hood and visually inspect the area where you seem to leaking from. Allow about 10 minutes and then look to see if you have a new puddle under the vehicle.
If it's a non-pressure leak, you should be able to spot it right away, most likely a loose hose clamp, If so, first look closely at the condition of the hose, if it looks okay go ahead and tighten the clamp, ( you often only need about 1 full turn on the screw/nut that tightens the clamp.)
As rubber hoses age they lose some of their integrity, so clamp should be checked atleast every six months.
If you find nothing leaking, it is likely a pressure leak that is often the result of the engine and coolant reaching their operating temperature and as they do the heat builds perssure and will usually force coolant out of any weak links in the cooling system.
Let the engine run 6 to 8 minutes to allow the vehicle to get to its normal operating temperature.
Look at your temperature gauge, your needle should be about in the middle. Go back and look in the engine compartment again and visually inspect for signs of leaks. You should be able to locate any pressure leaks at this point. As before, if you locate the leak, and it is at a hose, do a good visual inspection of the hose, and the clamp.
Good luck my friend!
