Small coolant leak
What is this part called that the thermostat mounts to? Its on a 2006 Explorer. Every vehicle i have has the thermostat on the water pump. In the one corner you can see a small coolant weep. Thanks in advance.

Pic looks NOT to be the F150 noted in your profile, but a 2006 Explorer with V6~4.0L~SOHC engine?
The infamous PLASTIC ThermoStat Housing!
Yours has a SingleClipMountedTempSensor & ForewardFacingTopCoverOutletRadiatorHoseBarb.
These FactoryOE\AfterMarket PLASTIC Housings are well known notorious leakers.
Best to replace\upgrade to an Aluminum ThermoStat Housing & new ThermoStat Valve.
Your local parts house will likely set a cheap PLASTIC housing in front of you
& does not stock Aluminum Housings; online RockAuto\Amazon\Ebay have them with price comparable to Plastic Housing.
Several items look rusty\crusty; Michigan winter road salt?
If any of your Coolant system Hoses, HeaterControlValve,HeaterCore Pump+Fan+Clutch, Radiator...
have never been serviced\flushed\replaced, it's time. The hoses+clamps look original.
While replacing the ThermoStat Housing, is a good time to replace the OilPressurized TimingTensioners;
that left TimingTensioner looks original?

Thank you. Its actually a vehicle my boss just bought for his wife to drive, even though she doesn't like it. I personally think its better than her clapped out 2010 town and country van but I'm a Ford guy. I will let him know. The tensioner must be similar/the same as the ones on my brothers 06 Ranger with a 4.0. Ill keep that in mind too. And yes, this vehicle lives in MI.

When 4WD is OFF, power is to the rear.
When 4WD at 4WH, power is to all wheels with hi gearing; ok for higher speeds.
When 4WD at 4WL, power is to all wheels with lo gearing; lo speed driving only.
