Hi i would like to help you out. Is your explorer a 4.0L engine. Ive included a pic of pic of the 4.0L here. If you have the 4.6L v8 let me know and I update this info. On the 4.0L engine it sounds like your thermostat housing is leaking. There is an o ring under the housing that I have seen leak before. Should be number 9 in the picture. the part number is XXXXX as well so you can get this o ring right from your local ford dealer. If you need further assistance please feel free to ask and please remember to click the accept button if I was able to help you in anyway. Thanks and good luck

Just a little note to tell you that the problem was with the thermostat housing itself where the upper and lower part of the housing is put together has a blown gasket and i dont know if you can buy this gasket or if you have to buy the whole thermostat plastic housing
