Just pulled out of my driveway to go to a charity walk in the city and I smelled antifreeze. Big Time. I turned around and pulled back in my drive. Antifreeze was sprayed all over my engine. I had a warranty on my car that I had paid for so I had it towed to the dealership. It ends up it would not pay for it. I have since found out that Ford used a not so great thermostat housing with a seam in it that can come apart in the Mustang and Explorer. This happened at 51,000 mi. I was fortunate that I was somewhere safe (just left the house) where I could immediately get the car off the road before it got hot and cause further damage. I have read up a little on it and it seems this is a problem that happens to a lot of people and I wish they would make a better part. I was told the thermostat and housing is in one unit and since my warranty did not pay for a thermostat....it would not pay for any of it. I wish they would recall this part and replace it with a good reliable sturdy housing. Mustangs aren't cheap. It's ridiculous to run into this problem. It could have ruined an engine or left me stranded somewhere I didn't want to be. Ford has to know about it. (the dealer's mechanic told me the same thing I read up on...Mustangs and Explorers have this housing that is known to crack) They need to man up and fix it.
