Replacing The Cylinder Head Temperature Sensor On A 2010 Ford Focus

[@alfonsoaltamirano6238]

You're a lifesaver, my car has been having these same issues and instead of spending a ton at a mechanic I'm gonna go tomorrow to Lowe's and get the tools to do it myself. Thank you so so much.

@@unemployedredneckhillbilly2023 Thanks for this very informative video as it matches my exact same issue. Got the Ford replacement but have yet to find a deep enough socket. Any suggestions? Thanks in advance.

[@jarrettmcgowan3663]

Great video. As a ford tech i see this broke CONSTANTLY. We have a few of these cars from the sheriff’s office, i call them cutesy, used for citizen observer patrol. Had 2 come in for an AC concern, neither of which i could verify, ac was ice cold. So i move on to doing a timing cover reseal/ valve cover gasket, and see the coolant light pop up for a split second while pulling it into my lift. So i get out and pop the grommet off, and what do you know, the locking tab was broke! And when that sensor is unplugged the AC shuts off too, thinking the car is overheating.. so i tell my apprentice to pull in the other, that we couldnt verify last week.. pop the grommet off that one and what do you know.. easy repair, these locking tabs constantly break being in that location; especially when oil leaks from the valve covers into that valley, theyll break on you every time. Good work 👍🏻

[@unemployedredneckhillbilly2023]

This sure seems to be a common issue with them from the comments. Luckily it's an easy fix. Thanks for watching.

[@jimpritz4169]

I have to admire your willingness to tackle something like this. I also have accumulated many older Craftsman tools even some my parents gave me when I was 16. Just an FYI if you ever have the need there is a KZbin channel from Avoca, NY by Eric O, called South Main Auto Repair. He is an amazing mechanic that gets jobs from other shops that have given up or just thrown parts at a problem. His diagnostic skills are epic and he has many videos on KZbin. Thanks for the video and sharing your solution.

[@unemployedredneckhillbilly2023]

Thanks. Usually finding a code can help narrow things down. Probably saved $200.00 over what the dealer would charge so its worth a try. I have many craftsman tools and the older ones are really good. I will check him out. Thanks for watching.

[@joehyundaitech7961]

just a little free tech tip when changing these out remove the number 2 and 3 cop coil on the pack for better access I have big hands otherwise its a tight fit and when trying to fit your fingers in there you dont have room and things can break. or you can just remove the number 2 cop to make more room

[@unemployedredneckhillbilly2023]

Hopefully it never has to be done again. Not to bad with the right socket. Thanks for watching.

[@esmith22001]

No check engine light or codes on my daughter's 5 speed manual trans Focus. Just revved to 4000 rpms at a stop. Temp gauge in instrument cluster read "cold" and rad fan only ran with AC on. Replace Temperature as described here. All is well now. thanks!

Thank you ! Thank you ! Thank you ! I thought that I also had a water temp. sensor, but I don't. Thanks for the heads up ! After I removed the rubber boot, I found my sensor and plugs swimming in oil, from a leaky valve cover gasket. I use permatex permashield on that type of gasket to prevent that from happening again. a little expensive but it doesn't fail ! !

@@unemployedredneckhillbilly2023 thanks I’ll try that. It’s possible when I was getting the cover off one fell but I thought the bolts are supposed to stay connected to the cover sense they don’t come all the way out when I was loosening them. Some came out most didn’t. Nonetheless, the most likely scenario is that the bolt fell down into the oil pan, one can hope.

Wife wifes car had a check engine light and some codes a couple of weeks ago. I will tell you what, I am NOT a fan of working on this new stuff. I must have stared at it scratching my head for half the day. I even told her "Lets park it and get you a new car" I ended up getting an Innova Fixassist 3100RS, I am not sure it helped me fix the car but it sure is a fancy piece of equipment. I am eger to learn more about how to use it.

[@unemployedredneckhillbilly2023]

That's funny. My wife said let's just get a new one also. She actually called the local Chevy dealer and asked if they would take a broken car as a trade in. Without some way to read the codes you can spend a fortune replacing parts. Luckily it was a cheap sensor. This one will be going down the road as soon as there is a decent affordable electric car now that gas is heading to $6.00 a gallon again.
