    Coolant Leak on Front of Engine (2007 4.6L V8 Mountaineer)

    Hi everyone. Over the past few months I noticed a very small amount off coolant on my driveway when the vehicle cools down after a long drive. It was never a concerning amount and due to the vehicles age I was not too concerned. I monitored the reservoir and it never reached a low level...

    1998 Explorer burning through Antifreeze

    I have a '98 Explorer, the engine and radiator were replaced in Dec. 2014 by my local Ford dealer. Since then it has been burning through antifreeze - and by 'burning through', I mean I put between 6-8 gallons in it per year since it was replaced, and on par to do the same this year. There are...

    Coolant dripping from under passenger seat

    I put in a new radiator yesterday. No drips from front end but there is a drip or leak from underneath passenger seat. It’s very faint but you can see where the snow is stained green. What is doing there ? Do coolant lines run that far back ? Thanks.

    08 Ltd 4.6 Radiator leak/replacement questions (I've joined the club)...

    Greetings, My 08 Ltd 4.6 radiator has had it. I am pretty sure the car was in an accident of some sort before I got it (with 60k) as there is some misalignment of some front end body parts. I *think* it is the original rad as it is stamped 10-17-2007 on the mfr date code. That said, the...

    My 08 Limited lost most of the water and went into self protect mode which scared the crap out of my son. I didn't know what is was until I read the owners manual. The stupid thing has no low coolant warning. The leak was hard to find because the leakage runs down the bottom of the hose then...
