Props to you Xlnt video. I just paid $275 to replace the damn temp sensor thinking the P0128 code was for the sensor, as I believed it was original and likely 200k miles old. Of course,...2weeks later same code comes up and and so it's on to the thermostat. which ill do myself now ! thanks again. ** I KNEW I shoulda replaced the T stat when i replaced one of those pesky leaking Coolant hoses tied to the Tstat housing 18 mo ago ...🤔🤬
Jfyi, im changing mine because after a water pump change and a new thermostat, the high-speed fan runs all the time. After some research, it was recommended to me to use the motocraft brand thermostat. I guess the 5.0 is picky about their thermostats. We'll see if it fixes the problem.
@@737mechanicmy sons 2014 f150 he says the heater is only blowing hot air if he accelerates at faster speeds and that his truck seems to be over heating? No temperature light comes on but he says it seems to be running hot going down the highway. I figured he either is low on coolant or it could be thermostat
@@Brumasterj Check the coolant level first, but it sounds like it could be the water pump but the thermostat would be easier than the water pump if you wanted to illuminate that first.
There is only 1 oring. You install the thermostat and then the o-ring unless you remove the housing from the block then there is an oring between the housing and the block. Below is a diagram showing the setup. #10 is the only oring required when replacing only the thermostat, but if you remove or replace the housing then you need o-ring #7 also. dz310nzuyimx0.cloudfront.net/strapr1/ba600726847ac4c8ec09625d9d8da21c/26701bad92ab34ea56caa8cdcfd13d5d.png
It appears you put the o-ring on the "backside" (in first) but it came out on the "frontside". Your pliars are stopping it from falling as you pulled it out. I'm still going to follow your steps tomorrow with one little adjustment 😊 Thanks for the video!
Is someone able to clarify the o-ring comments. Is there 1 or 2, and which side does it go on if there is only one. The video only shows 1, but you switch sides on the install.
My truck is at the dealer and got locked down with the power outage (hurricane) I am seriously considering getting it back from them as soon as they open and do the thermostat myself. What happened with mine is that the aux. Fan refused to turn on, and my engine was overheating. I am thinking the thermostat was sticking closed, and the coolant temp never went high enough to turn the fan on. I am thinking this because the level of the reservoir never moved at all while the engine was overheating. Then all of a sudden it popped open and started cooling and the res. level dropped. Does this sound like sound logic? They have had it over a week now and I need it BACK!!

Working on cars in the rain just proves you're a man. My nephew spent his birthday with me and his grandpa working on cars in the rain. Good stuff.
Thanks for showing this procedure as I own a 2015 F150 with 5.0…this will help me in the future, I am sure

Did it fix the fan issue
Mine has same issues
Same issue. Did it work?
Did it fix the problem for yall?
Im going to try this after trying the expansion valve and every other possible fix that didn’t work
So did he say if that fixed his issue or was there another issue
That fixed it.

You know with how easy it was, and the truck being older by age anyway, and having a few miles, not really a loss to do a thermostat anyway.
There are 2 O rings required. 1 goes up in the housing before the thermostat.

There is only 1. Number 10 in the diagram.
