How much fluid loss when doing this? I need to do it and have the new thermostat but only have half a gallon of Motorcraft coolant, do I need to get another jug?

How to install a new Thermostat 2019 F150 Ecoboost 15+ Mishimoto 160
160 degree mishimoto thermostat installm.youtube.com
Maybe 2 gallons
But the techs just use the radiator drain valve dump it in a bucket and if its clean they just put it back in.
YouTube videos show the drain valve process its super simple. Definitely an easy handy dad job if you have time.

Thanks, I will watch the video, I suspected it lost a lot of fluid with how low it seems to be. My old dodge 5.9 is way up high and hardly loses a drop when changing the thermostat on a cold engine.

Don’t over torque the housing nuts. Its plastic. Not sure what torque they use. But be careful about it.
The radiator drain valve is pretty simple guessing they dump about 1/2 the radiator given the thermostat is about mid way up the coolant loop.

When I changed the thermostat in my 2019, I used about 1.5 gallons. At 65k miles, it was a good time to replace the anti-freeze anyway so I drained the radiator. Super simple and took less than a couple of hours from start to complete cleanup in my garage. On my '19 it is 3 bolts to remove the thermostat housing and you can do it without removing anything else.
If you have an oil drain pan, you can place that under the radiator drain plug and drain the radiator. It will take about 30-45 minutes or so to drain (it doesn't come out very fast-even with the overflow cap off), then you can remove the 3 bolts on the thermostat housing to remove/replace the thermostat.
