2012-2018 Ford Focus Thermostat Replacement How-To

[@Poom831]

I replaced the thermostat and water pump this morning. By far the easiest thing I’ve ever changed. You video helped out great.

[@likividesigns]

Thanks for the video bro, good stuff helping people avoid pulling their car apart to change thermostat. Please don't tell people that distilled water doesn't boil, it boils at the same temp as tap water.

[@Dhi-fe5eu]

That has to be the best video. Start to finish. Spoke very clear. You did a great job. Look forward to seeing more of your videos.

[@jfunk526]

Thank you ! I followed your video step by step and successfully changed thermostat in my daughters 2012 Focus. Much appreciated. Keep up the GREAT work.

[@JustinWood-o5h]

Thanks for the vid. Looked at my thermostat, low and behold, it is leaking at the back of it! Hence my mysterious coolant leak.

[@BLUECOLLARGARAGE]

Glad you were able to find it.

[@jadewulf3625]

Awesome video ! Not one swear word. I need to follow your example. Thanks so much !

[@stevescam001]

Thanks so much for the video. I'll go ahead and do this before my thermostat actually conks out.

[@rocks4brains]

Thanks. To be a successful mechanic these days you have to have small hands. I have used a very thin grease coating on hose connections or some WD40 to help them slip and seal. On those nuts I tighten until they get decidedly bottomed out and then another twist each or no more than an 8th additional turn - plastic parts don't lend a lot of confidence either side. The threads are super fine so they don't back out. Use good judgement but that O ring gasket is good.

[@Chris-pj1os]

Good job on the video and everything. Much appreciated.

[@ephraimmiller9272]

I did this and my car wouldn't start after. So, just to let people know, there is a connection right above the hoses, going into the housing. That connection leads to the fuel pump relay. If your car wont start after, that might be it. When I pushed it in, it only moved about an 1/8th of an inch. Looking at it, I thought it was OK, until I pushed it in. Just thought I would put this out there, just in case.

[@BLUECOLLARGARAGE]

Thanks for the extra info.

[@Dhi-fe5eu]

That was a great video. You spoke very clear and I hope you make more videos.

[@paulbangert8422]

Excellent well done video one of the best I’ve seen. Great work.

[@bigjohnson7415]

Nice job. I have a 2012 5 speed, been a great car. I currently have a heater hose leaking at the firewall, thought it might have been the heater core, but hopefully got lucky. Ordered the hose the other day plus the tool to remove it. I'm also lucky, I work on jets, so mechanically inclined, plus I have skinny arms and long fingers!🤣 Fine work my friend!👍

[@AMScotty]

I do as well. Not often, I see others who are A&Ps around these kinds of videos.

[@bigjohnson7415]

@@AMScotty Yessir! Not a real popular profession, what with all the outsourcing of our jobs to other countries over the last 4 decades. I'm close to the end myself, so not sure what the future holds for the profession in the future.

[@snipermitchell6373]

Great video I was nervous about doing this repair plus almost got the thermostat by itself

[@mini_worx]

Great video 😊

[@juanjoalbarello442]

Good morning, how do I know if I should change the temperature sensor? What I see is that when I start my vehicle in the morning the needle goes up somewhat quickly to the middle (between 30 seconds and a minute letting idle) but it never goes beyond that no matter if I drive a lot or leave the car running for several hours on a hot day... is that a symptom of a faulty temperature sensor? or that could be a symptom of the Thermostat that is failing?

[@BLUECOLLARGARAGE]

If it’s in the middle that is normal operating temperature. What does it do with just the key on and engine not running?

[@user-vq8op4mh8s]

Did you find a solution to your problem? Please reply

[@prestoVMX]

@@user-vq8op4mh8s He must've gotten caught up in the "middle" of something

[@joanrusling5397]

Nice job! Thanks for the good explanation.

[@Peterpepper25]

Basically if your gonna do the water pump you might as well remove the belt /tensioner and go to work on the water pump as well. I replace in pairs

[@natalialopez4279]

Before I change the thermostat on my 2012 Ford Focus is it a must to drain the coolant first? My coolant seems to be fine, this is my first time changing the thermostat on my own!

[@BLUECOLLARGARAGE]

Although draining the coolant isn’t a must but if you don’t drain it down at least a 1/4 of the way it will make a big mess once you pull the thermostat housing off. So at minimum you’ll want to drain at least some of the coolant out first.

[@Wadeifer]

From another site, what does it mean to backfill the block to prevent an air pocket? Is that necessary?

[@BLUECOLLARGARAGE]

It just means filling the block with coolant at the thermostat hole before you install it but if you do it the way I did in the video you won’t have any problems. Most of the air bubbles will work there way out into the coolant reservoir after a day of driving.

[@dadokrstic]

Great vid! Thanks a lot!

[@rjbass338]

just to note that distilled water does boil.

[@blass5506]

I noticed that you installed the new thermostat without gasket and sealant ? Please reply thank you

[@Kayakinbassbusta]

These have a rubber gasket that does not require RTV

[@BLUECOLLARGARAGE]

The rubber gasket is on there at scene 13:04.

[@blass5506]

THank you for replying

[@hectorocaranza3587]

Muy buen video!!! Exelente!!! Saludos!!!

[@mikehinson7063]

did you have to end up taking the headlight off?

[@BLUECOLLARGARAGE]

Nope

[@SAMEntalhealth]

Can you do me a favor and tell me where the EGR is on this model😅😅😅😅😅😅 it's killing me I've done and replaced every component under the engine accept my EGR and I'm stressing😅😅😅😢😢

[@BLUECOLLARGARAGE]

What year is your Focus? The 2012-2018 ford focuses are VVT (variable valve timing) engines so there is no egr valve. The vvt controls the timing of the gases entering and exiting the combustion chamber thus eliminating the need for an egr valve.

[@SAMEntalhealth]

@BLUECOLLARGARAGE omg thank you!!!!!!!! 👊

[@BLUECOLLARGARAGE]

@@SAMEntalhealth anytime brother!

I definitely just subscribe! ❤❤❤​@@BLUECOLLARGARAGE

​@@BLUECOLLARGARAGEfunny thing is is yours and mine are the exact identical if including the paint😅😅😅

[@andyzaluski]

Thank you for the video.

[@Adals]

Wich engine is it?

[@BLUECOLLARGARAGE]

It’s the 2.0

[@istanbul0562]

Anyone done this on the 1.6 petrol ? Is it any easier or harder

[@philipchristy9210]

It’s. A 1.6 4 cylinder,is that called eco boost USA…?

[@BLUECOLLARGARAGE]

There is a 1.6 non eco boost and a 1.6 turbo that is a eco boost but those are found in the ford fiestas.

[@DougKoper]

Thanks for the help.

[@wolf19i7]

Sounds like the blower motor is pretty loud in these cars.

[@BLUECOLLARGARAGE]

Yeah it is pretty loud on max setting.

[@danielmckinzie4857]

2012 you will have to loosen and hold the alternator out of the way to reach the bottom bolt. 13mm leave it hanging on top bolt and just move the bottom out of way.

[@ScottieNicholas-rw1dg]

The cost and how to change the thermostat on a 2008 Ford focus

[@memphis_sean8169]

Is the thermostat a wear item or 🤷

[@BLUECOLLARGARAGE]

In my opinion it is, just because it goes through so many heat and cooling cycles.

[@fairfax_fran5109]

Work on it and include the water pump wow the thermostat was way more difficult than the water pump

[@mipollito1000]

Tengo un carro igual, y me marca fallo en el Sensor MAP, pero no lo encuentro sabrás donde esta ubicado.

[@BTKKILLER1]

Que

[@josephdeakyne197]

Needs 4 bolts equal distribution will leak again bad design

[@chrisschultz6129]

Coolant leaks, engine overheats, new engine is too much, customer buys new car. Maybe a good design (for the auto industry, not for the customer)

[@alanalvarado3133]

The car wasn't leaking coolant. I think you misunderstood the video.

[@Wayno228]

Great vid
