Driving my car, and I hear the radiator fan, it was very loud.

Was driving in third at 2,000RPM, and i see that the temperature of my engine was inreasing, it was about 3/4 of the way to it being hot, went back down and stayed above average.

Parked my car outside of house, opened the hood, and steam was coming from under the intake manifold, and throttle body, and some steam was coming from the sides of the intake manifold in the front


What can this be?
Am I at the point where selling the car is my best bet?

car has 86,6XX miles.

My car has recently had the exact same problem, a 2006 v6 with 81k at the time, besides the fact that i was hot-******* for my girlfriend not staying at 2k rpm haha. I did the same as you, wen through forums, looked online. and found that many 2005-2009 mustangs had this similar problem around 70-90k miles. if you look at where the leak is coming from you will probably notice a crack in the part. Me and my dad were able to replace this at a total cost of about 80$ and i havent had a problem 10,000 miles later. if you need more info than that, email me it will get you a faster response. i can talk to my dad and give you more detail if needed. Hope this helps, goodluck!

Sounds like the thermostat housing - it is a plastic piece and will crack at the seam. I haven't had the problem in 194,800 miles thankfully, but seems to be the common issue when you see this.

Selling your car over a cheap part? And at 86,000 miles if you have done regular maintenance you have a lot of miles to go. Like I said, closing in on 195,000 on mine this week - and that is after a 75 shot of nitrous for two racing seasons, and a supercharger since 90,000 miles.

Maybe if you cant hack it, sell it, thats my motto.
Or replace the thermostat housing and the thermostat
with a 175 degree thermostat instead of the 190 degree
OEM thermostat.
Mine runs at 175 degrees and I am laughing all the way to
the anti heat soak bank...

Get the veggies out and make use of the steam until you replace the t-stat housing. +1 on it being a common, chronic issue.
